Securely fasten the product in a vertical upright position on a solid structure with the productlogo facing the front. Do not mount the product upside down or install in a horizontal positionas proper ventilation will be inhibited.3. As heat is generated during inverter operation, the spaces shown in Fig. 2-2-1 are required toensure sufficient cooling. Since heat radiates upward, do not install the product beneathheat sensitive equipment.4. During operation, the heat sink may reach a temperature of 90ºC (194ºF), therefore ensure thatthe material surrounding the product can withstand this temperature.DANGERInstall this product on nonflammable material such as metal.________________________________________________________________________TECO – Westinghouse Motor Company Installation Environment & Method 5

EQ5 AC Drive Operations Manual5. When installing this product in a control panel,ensure that the ventilation is sufficient to prevent theambient temperature of the inverter from exceedingthe specified value. Do not install the product in anarea where there is inadequate ventilation,6. If two or more inverters must be installed in thesame equipment or control panel, arrange the unitshorizontally (side by side) to minimize the effect ofheat. If two or more inverters must be installedvertically (one on top of the other), place aninsulated plate between the inverters to minimize theeffect of heat.7. When shipped from the factory, inverters provideinternal cooling inside panel. An inverter of30HP/CT, 40HP/VT or less can be converted to anexternal cooling simply by adding an optionalmounting adapter.Fig.2-2-2In an external cooling system, the heat sink radiates about 70% of total inverter heat (totalloss) and can be placed outside the control panel (see Fig. 2-2-2). When doing this, ensurethat heat sink surfaces are kept free of foreign matter.DANGER・In the case of external cooling system, cover the back of the inverterin order to prevent the exposure of the power capacitor and brakingresistor as electric shock may result.・Ensure that the inverter and heat sink surfaces are kept free offoreign matter such as lint, paper dust, small chips of wood or metal,and dust, as fire may result.An inverter of 40HP/CT, 50HP/VT or more can be converted to an external cooling type simply bymovingupper and lower mounting brackets as shown in Fig. 2-2-3.

Always connect input power to the main circuit power terminals L1/R, L2/S, and L3/Tof the inverter. Check that the input voltage to be applied is within the maximum allowablevoltage marked on the nameplate.2. Always connect the power output terminals U, V, and W to the motor. Check that outputvoltage rating is correct for the motor being used.DANGER- Do not connect the input voltage to the motor terminals U, V, and W asextreme damage and / or injury may result.3. Using the proper wire size and type, always bond the ground terminal to a reliable groundconnection to prevent dangerous situations such as the possibility of fire or electrical shockand to minimize electrical noise.4. Use a secure reliable cable crimp connection between the terminal and a cable.5. After terminating the wiring connection, ensure the following:a. The connection is correct.b. All necessary connections have been made.c. There is no short-circuit or ground fault between terminals and cables.6. If a wiring change needs to be made after power-up, wait at least 5 minutes before makingany wiring changes. Also ensure that the charge indicating LED is off. This is necessarybecause the DC power section capacitor(s) does not discharge immediately after power-downand maintains lethal voltages. The actual DC voltage may also be checked with a multimeterand should be 25VDC or less. If short circuiting the DC voltage after power-down, sparksmay occur.DANGER• Always properly ground the inverter otherwise electric shock or firemay result.• Ensure that a licensed specialist performs all wiring and that all codesare met.• Confirm that the power is turned off and that the charge indicator is off(Wait 5 minutes for 30HP/CT, 40HP/VT and less, 10 minutes for40HP/CT, 50HP/VT or above) before removing any protective covers aslethal voltages are present and electrical shock may result.NOTES______________________________________________________________________TECO – Westinghouse Motor Company Electrical Connections 8

EQ5 AC Drive Operations Manual2. Inverter output terminals (U, V, W)a. Connect these terminals to a 3-phase motor in the correct phase sequence. If thedirection of motor rotation is incorrect, swap any two of the U, V, and W phases.b. Do not connect a power factor correction capacitor or surge suppressor to the inverteroutput.c. If the cable from the inverter to the motor is excessively long, a high-frequency currentcan be generated by stray capacitance between the cables and result in an overcurrenttrip of the inverter, an increase in leakage current, or a reduction in current indicationprecision.d. When a motor is driven by a PWM-type inverter, the motor terminals may be subject tosurge voltage generated by PWM switching. If the motor cables are excessively long,particularly the 460V series units, the surge voltage will deteriorate motor insulationover time. To prevent this, use the following guidelines:Inverters 7.5HP/CT, 10HP/VT and HigherMotor Insulation Rating 1000V 1300V 1600V460 VAC Input Voltage 66 ft (20 m) 328 ft (100 m) 1312 ft (400 m) *230 VAC Input Voltage 1312 ft (400 m) * 1312 ft (400 m) * 1312 ft (400 m) *Inverters 5HP/CT/VT and SmallerMotor Insulation Rating 1000V 1300V 1600V460 VAC Input Voltage 66 ft (20 m) 165 ft (50 m) * 165 ft (50 m) *230 VAC Input Voltage 328 ft (100 m) * 328 ft (100 m) * 328 ft (100 m) ** In this case the cable length is determined by secondary effects and not voltagespiking.Note: When a motor protective thermal O/L relay is inserted between the inverter and the motor, thethermal O/L relay may malfunction (particularly in the 460V series units), even when the cable lengthis 165 feet (50m) or less. To correct this, insert a filter or reduce the PWM carrier frequency. (Usefunction code “F26 Motor sound”.)3. Auxiliary control-power input terminals (R0 and T0)The inverter will operate even if poweris not provided to these terminals. If aprotective circuit is activated and themagnetic contactor on the inverterpower input side is opened (off), theinverter control circuit power, the alarmoutput (30A, B, and C), and the keypaddisplay will lose power. To prevent this,the same AC power as supplied to themain input circuit must be supplied (asauxiliary control power) to the auxiliarycontrol - power input terminals (R0 andT0). (see Fig. 2-3-2)a. To ensure effective noise reductionwhen using an input noise filter, theoutput from the filter must go tothe auxiliary control-power inputterminals. If these terminals areFig. 2-3-2 Connecting the Auxiliary Control-PowerInput Terminalsconnected to the input side of the filter, the noise reduction is much less effective.______________________________________________________________________TECO – Westinghouse Motor Company Power Terminal Designations & Wiring 12

EQ5 AC Drive Operations Manualb. When the RCD (Residual-current Protective Device) is installed (30HP/CT, 40HP/VT or less), theterminal R0and T0 should be connected to the output side of the RCD. If they are connected to the input side,the RCD will malfunction because the power supply of the inverter is three phase and theR0 and T0 input is single phase. If it is required to connect terminals R0 and T0 are to the input sideof the RCD, an isolation transformer is required as shown on the Fig. 2-3-2.4. Connecting a DC link choke to terminals (P1 and P (+))a. Before connecting a DC link choke to these terminals, remove thefactory-installed jumper. (Fig. 2-3-3)b. If a DC link choke is not used, do not remove the jumper.Note: For inverters of 100HP or more, the DC link choke is providedas separate standard component and should always beconnected. For inverters less than 100 HP, the DC link chokeis not provided and is optional.P1DC Link ChokeXInverterP(+)Fig. 2-3-3 Remove Jumper4. Connecting an external braking-resistor to terminals (P (+) and DB) (10HP/CT, 15HP/VT or less)(Fig. 2-3-4). For inverters 10HP/CT, 15HP/VT or less, a built-in braking resistor is connected toterminals P (+) and DB. If this braking resistor does not provide sufficient thermal capacity (e.g.high operating duty cycle or high inertia loads), an optional external braking resistor must beinstalled to improve braking performance.a. Remove the internal braking resistor fromterminals P(+) and DB and Insulate theterminals with adhesive insulation tape, etc.b. Connect terminals P(+) and DB of the externalbraking resistor to terminals P(+) and DB of theinverter.c. The wiring (cables twisted or otherwise) shouldnot exceed 16ft (5m).6.

UP to31 inverters can be connected using the daisy chain method.Terminal for connecting the shield of the communicationcable. The terminal is electrically floating.(1) Analog input terminals (13,12,V2,C1,and 11)a. These terminals receive analog signals that may be affected by external noise. The cables should be as shortas possible (66ft /20m or less), be shielded twisted cable, and must be properly grounded. If the cables areaffected by externally induced noise, the shielding effect may be improved by connecting the shield to terminal[11]. (see Fig. 2-3-8)b. If contacts are used to connect to these circuits, twin (bifurcated type) contacts for handling low levelsignals must be used. A contact must not be connected to terminal [11].c. If an external analog signal output device is connected to these terminals, it may malfunction as aresult of inverter noise. To prevent malfunction, connect a ferrite core or capacitor to the external analogsignal output device as shown in Fig. 2-3-9.______________________________________________________________________TECO – Westinghouse Motor Company Control Terminal Designations & Wiring 19

EQ5 AC Drive Operations Manual(2) Digital input terminals (FWD, REV, X1 to X9, and CM)a. Digital input terminals FWD, REV and X1 toX9 are generally turned on or off by switchingthe input to (P24) +24V (source logic) or to(CM) 0V (sink logic). If the digital inputterminals are turned on or off by a PLC withopen collector using an external power supply,a resulting bypass circuit may cause theinverter to malfunction. To prevent this, connectthe PLC terminal as shown in Fig. 2-3-10.b. When using a dry contact input such as arelay, highly reliable contacts capable ofhandling low level signals must be used.(3) Transistor output terminals (Y1 to Y4, CME)a. Refer to the circuit configuration in Table 2-3-3 Transistor Output and confirm the polarity of theexternal power supply.b. When connecting a control relay to the transistor output, connect a transient absorbing diodeto both ends of the relays’ exciting coil.(4) Sink or Source Logic selectiona. The slide switch SW1 located on the control board, sets the digital inputs for sink or sourceinput logic. The factory default is the sink position and is most commonly used in the US whilesource logic is common in Europe.b. For proper input digital connections, refer to the EQ 5 wiring diagram as well as other sectionscovering this subject. Ensure that the correct position is selected for a particular application.(5) Othersa. To prevent faulty operation as a result of noise, the control terminal cables should be placed asfar as possible from the main power cables.b. The control cables inside the inverter must be secured to prevent direct contact with the mainpower section, such as the power terminal block.(6) Wiring of the control circuit (40HP/CT, 50HP/VT or greater)a. Pull out the control circuit wiring along the left panel as shown in Fig. 2-3-11.b. Secure the cable binding hole A on the left wall of the power terminal block using a cable tie.Note: The cable tie should not exceed 0.14 ”(3.5mm) in width and 0.06” (1.5mm) in thickness.c. When an optional PC card is mounted, the signal cables must be secured to cable bindinghole B.______________________________________________________________________TECO – Westinghouse Motor Company Control Terminal Designations & Wiring 20

EQ5 AC Drive Operations Manual5. Parameters F,E,C,P,H, A and UThis section covers parameters F,E,C,P,H, A and U which can be set via the digital operator(see Sect. 4) to achieve a specific performance for a particular application. For most general purposeapplications, the factory settings are sufficient and will not need to be changed. If the parametervalues are to be changed, it is recommended that resulting overall drive performance be evaluated toavoid any unwanted performance issues.5-1 Parameters Summary ListThe following tables show the setting range, LCD readout, factory setting, and whether the value canbe changed while the drive is operational.Para.No.F ParametersNAME LCD Display Setting range UnitMin.UnitFactory setting30HP/CT40HP/VT40HP/CT50HP/VTF00 Data protection F00 DATA PRTC 0, 1 - - 0 NF01 Frequency command 1 F01 FREQ CMD 1 0 to 11 - - 0 NF02 Operation method F02 OPR METHOD 0 to 4 - - 0 NF03 Maximum frequency 1 F03 MAX Hz-1 50 to 120Hz Hz 1 60 NF04 Base frequency 1 F04 BASE Hz-1 25 to 120Hz Hz 1 60 N0V: (Output voltage proportional toF05 Rated voltage 1 (at Base frequency 1) F05 RATED V-1230:(230V class)source voltage)V 1 460:(460V class)80 to 240V: (230V class)N320 to 480V: (460V class)F06 Maximum voltage 1 (at Maximum frequency 1) F06 MAX V-180 to 240V: (230V class)230:(230V class)V 1320 to 480V: (460V class) 460:(460V class)NF07 Acceleration time 1 F07 ACC TIME1F08 Deceleration time 1 F08 DEC TIME10.01 to 3600s s 0.01 6.0 20.0 YF09 Torque boost 1 F09 TRQ BOOST1 0.0, 0.1 to 20.0 - 0.1 0.1 YF10 Electronic (Select) F10 ELCTRN OL1 0, 1, 2 - - 1 YF11 thermal 1( Level) F11 OL LEVEL1 INV rated current 20 to 135% A 0.01 Motor rated current YF12 (Thermal time constant) F12 TIME CNST1 0.5 to 75.0 min min 0.1 5.0 10.0 N[Up to 10HP/CT, 15HP/VT]0Electronic thermal overload relay0, 2F13F13 DBR OL- -(for braking resistor)[15HP/CT, 20HP/VT and above ]00YF14 Restart mode after momentary power failure F14 RESTART 0 to 5 - - 0 NF15 Frequency limiter (High) F15 H LIMITERY0-120Hz Hz 1 70F16 (Low) F16 L LIMITER NF17 Gain (for freq. set signal) F17 FREQ GAIN 0.0 to 200.0% % 0.1 100.0 YF18 Bias frequency F18 FREQ BIAS -120.0 to +120.0Hz Hz 0.1 0.0 YF20 DC brake (Starting freq.)

The drive outputstops and the motor will coast to a stop.If undervoltage is detected, the drive output stops and themotor will immediately coast to a stop. A drive fault is notactivatedWhen the DC bus voltage reaches the continue operationvoltage level (H15), a controlled deceleration to a stop occurs.The inverter collects the inertia energy of the load to maintainthe DC bus voltage and controls the motor until it stops, thenan undervoltage fault (LU) is activated.The drive will automatically decrease the deceleration time ifnecessary. If the amount of inertia energy from the load issmall, and the undervoltage level is achieved before the motorstops, the undervoltage fault is immediately activated and themotor will coast to a stop.When the DC bus voltage reaches the continue operationvoltage level (H15), energy is collected from the inertia of theload to maintain the DC bus voltage and extend the ridethrough time. The drive will automatically adjust thedeceleration rate to maintain DC bus voltage level. Ifundervoltage is detected, the protective function is notactivated, but drive output stops and the motor coast to a stop.If undervoltage is detected, the protective function is notactivated. The drive output stops and the motor will coast to astop.If undervoltage is detected, the protective function is notactivated, but output stops.The drive operation is not automaticallyrestarted.

Input a resetcommand to restart operation.The drive operation is not automaticallyrestarted. Input a reset command andoperation command to restart operation.Operation is automatically restarted.For power recovery during ride-through thedrive will accelerate directly to the originalfrequency. If undervoltage is detected,operation automatically restarts with thefrequency at the time that the undervoltageis detected.Operation is automatically restarted withthe frequency at power failure.Operation is automatically restarted withthe frequency set by F23, "Startingfrequency."Note1) When the function code H18(Torque control) is excluding "0" and Motor 1 is selected, the inverter will trip at powerrecovery if function code F14 is set to between "2" and "5". This operation is same as F14 is set to "1".Function codes H13 to H16 are provided to control a restarting operation after momentary power failure. These functionsshould be understood and used. The pick-up (speed search) function can also be selected as a method of restarting whenpower is recovered following a momentary failure. (For setting details, see function code H09.)The pick-up function searches for the speed of the coasting motor to restart the motor without subjecting it to excessive shock.In a high-inertia system, the reduction in motor speed is minimal even when the motor is coasting. A speed searching time isrequired when the pick-up function is active. In such a case, the original frequency may be recovered sooner when the functionis inactive and the operation restarted with the frequency prior to the momentary power failure.The pick-up function works in the range of 5 to 100 Hz. If the detected speed is outside this range, restart the motor using theregular restart function.WARNING Automatically restart could be provided at power recovered, if "Restart mode aftermomentary power failure" is valid. The machine should be designed to human safety when restarting.Otherwise accidents may result.TECO–Westinghouse Motor Company Function Explanation 51

An auto tuning operation should beperformed for other motors.The rated current of the motor must not be significantlyless than the rated current of the inverter. A motor tworatings lower in capacity than the nominal applied motorfor the inverter should be used at the minimum(depending on the model).To prevent leakage current and ensure accurate control,the length of the cable between the inverter and motorshould not exceed 164ft(50m).When a reactor is connected between the inverter andthe motor and the impedance of the wiring cannot bedisregarded, use P04, "Auto tuning," to rewrite data.If these conditions are not satisfied, set 0 (Inactive).TECO–Westinghouse Motor Company Function Explanation 56

When the DC injection brakefunction is active, “RUN” signal is off.Frequency equivalence signal [FAR]See the explanation of function code E30 (frequencyarrival [detection width]).Frequency level detection [FDT1]See the explanation of function codes E31 and E32(frequency detection).Undervoltage detection signal [LV]If the undervoltage protective function activates, i.e.when the main circuit DC voltage falls below theundervoltage detection level, an ON signal is output. Thesignal goes off when the voltage recovers and increasesabove the detection level. The ON signal is retainedwhile the undervoltage protective function is activating.Undervoltage detection level: 230V series: 200V, 460Vseries: 400V.Torque polarity [B/D]This function determines the torque polarity calculated inthe inverter and outputs a signal indicating driving orbraking torque. An OFF signal is output for drivingtorque; an ON signal is output for braking torque.Torque limiting [TL]When the torque limiting activates, the stall preventionfunction is automatically activated to change the outputfrequency. The torque limiting signal is output to lightenthe load, and also used to display overload conditions onthe monitor device. This ON signal is output during thecurrent or torque is limited or power regeneration isprevented.Auto-restarting [IPF]Following a momentary power failure, this functionreports the start of the restart mode, the occurrence ofan automatic pull-in, and the completion of the recoveryoperation.Following a momentary power failure, an ON signal isoutput when power is recovered and a synchronization(pull-in) operation is performed. The signal goes offwhen the frequency (before power failure) is recovered.For 0Hz restart at power recovery, no signal is outputbecause synchronization ends when power is recovered.The frequency is not recovered to the frequency beforethe power failure occurrence.Overload early warning [OL1]Before the motor stops by the trip operation of anelectronic thermal O/L relay, this function outputs an ONsignal when the load reaches the overload early warninglevel. Either the electronic thermal O/L relay earlywarning or output current overload early warning can beselected.For setting procedure, see “E33 Overload early warning(operation selection)”, and "E34 Overload early warning(operation level)."Note: This function is effective formotor 1 only.Keypad operation mode [KP]An ON signal is output when operation command keys( FWD , REV and STOP ) on the keypad panel canbe used (i.e., 0 set in "F02 Operation") to issue operationand stop commands. This signal is OFF when thefunction H30(Serial link) is set to communication side.TECO–Westinghouse Motor Company Function Explanation 62

Inverter stopping [STOP]This function outputs an inverted signal to Running(RUN) to indicate zero speed. An ON signal is outputwhen the DC injection brake function is operating.Ready output [RDY]This function outputs an ON signal when the inverter isready to operate. The inverter is ready to operate whenthe main circuit and control circuit power is establishedand the inverter protective function is not activating.About one second is required from power-on to ready foroperation in normal condition.Line/Inv changeover [SW88] [SW52-2] [SW52-1]To perform switching operation between the line and theinverter, the sequence prepared in the inverter can beused to select and output signals for opening and closingthe magnetic contactors connected to the inverter. Asthe operation is complex, refer to technicaldocumentation for the EQ5 series when using thisfunction.As the sequence will operate automatically when SW88or SW52-2 is selected, do not select when not using thesequence.Motor 2 /Motor 1 [SWM2]When a signal for switching to motor 2 is input from theterminal selected by terminals [X1] to [X9], this functionselects and outputs the signal for switching the magneticcontactor for the motor. As this switching signal is notoutput during running including when the DC injectionbraking function is operating, a signal must be re-inputafter output stops.Auxiliary terminal [AX]When an operation (forward or reverse) command isentered, this function outputs an ON signal. When astop command is entered, the signal goes off afterinverter output stops. When a coast-to-stop commandis entered and the inverter protective function operates,the signal goes off immediately.Time-up signal for pattern operation [TU]When the pattern operation stage changes, this functionoutputs a one-shot (100ms) ON signal to report a stagechange.Cycle completion signal for pattern operation [TO]When the seven stages of a pattern operation arecompleted, this function outputs a one-shot (100 ms) ONsignal to report the completion of all stages.Stage No. indication for pattern operation [STG1] [STG2] [STG4]During pattern operation, this function reports the stage(operation process) being operated.Pattern operation Output terminalstage No. STG1 STG2 STG4Stage 1 on off offStage 2 off on offStage 3 on on offStage 4 off off onStage 5 on off onStage 6 off on onStage 7 on on onWhen pattern operation is not activated (i.e., no stage isselected), the terminals do not output a signal.Alarm indication [AL1] [AL2] [AL4] [AL8]This function reports the operating status of the inverterprotective function.Alarm detail(inverter protective function)Output terminalAL1 AL2 AL4 AL8Overcurrent, ground fault, fuse blown on off off offOvervoltage off on off offUndervoltage shortage, input phase failure on on off offMotors 1 and 2 overload off off on offInverter overload on off on offHeat sink overheating, inverter inside overheating off on on offExternal alarm input, braking resistor overheating on on on offMemory error, CPU error off off off onKeypad panel communication error, option communication error on off off onOption error off on off onOutput wiring error off off on onRS-485 communication error on off on onNot Used EQ5 off on on onIn normal operation terminals do not output a signal.Fan operation signal [FAN]When used with "H06 Cooling fan ON/OFF control," thisfunction outputs a signal while the cooling fan isoperating.Auto-resetting [TRY]When a value of 1 or larger is set to "H04 Retryoperating," the signal is output while retry operation isactivating when the inverter protective function isactivated.Universal DO [U-DO]Assigning value "27" to a transistor output terminalrenders the terminal a universal DO terminal.This function enables ON/OFF through the RS-485 andBUS option.This function serves only to turn on and off the transistoroutput through communication and is not related toinverter operation.Overheat early warning [OH]This function outputs a early warning signal when heatsink temperature is (overheat detection level - 10℃) orhigher.Life expectancy detection signal [LIFE]When either of data for the Life expectancy judgmentof the function code:U09 to U11 reaches at the Lifeexpectancy judgment level, the ON signal is output.However, the inverter does not do alarm.Moreover, the alarm output for any fault (30A, 30B,30C ) does not operate.FunctioncodeParts ofLife expectancy judgmentLife expectancyjudgment levelU09 Capacitor in main circuit 85% or less of the initial valueU10 Electrolytic capacitor on PCB 61,000 hoursU11 Cooling fan 25,000 hoursU59 DC fan broken for stir internalunit up[40HP/CT, 50HP/VT or more isannunciated.]DC fan is brokenTECO–Westinghouse Motor Company Function Explanation 63

H13Instantaneous switching to another power line (when thepower of an operating motor is cut off or power failureoccurs) creates a large phase difference between theline voltage and the voltage remaining in the motor,which may cause electrical or mechanical failure. Torapidly switch power lines, enter the remaining voltageattenuation time to wait for the voltage remaining in themotor to attenuate. This function operates at restartafter a momentary power failure.H 1 3 R E S T A R T TSetting range: 0.1 to 5.0 secondsWhen the momentary power failure time is shorter thanthe wait time value, a restart occurs following the waittime. When the power failure time is longer than thewait time value, a restart occurs when the inverter isready to operate (after about 0.2 to 0.5 second).H14This function determines the reduction rate of the outputfrequency for synchronizing the inverter output frequencyand the motor speed. This function is also used toreduce the frequency and thereby prevent stalling undera heavy load during normal operation.H 1 4 F A L L R A T ESetting range: 0.00, 0.01 to 100.00 Hz/sWhen 0.00 is set, the frequency is reduced according tothe set deceleration time.Note:A too large frequency reduction rate is may temporarilyincrease the regeneration energy from the load andinvoke the overvoltage protective function. Conversely,a rate that is too small extends the operation time of thecurrent limiting function and may invoke the inverteroverload protective function.H15Auto-restart (Restart time)Auto-restart (Freq. fall rate)Auto-restart (Holding DC voltage)This function is for when 2 (deceleration-to-stop at powerfailure) or 3 (operation continuation) is set to "F14Restart after momentary power failure (operationselection)." Either function starts a control operation ifthe main circuit DC voltage drops below the set operationcontinuation level.H16As the power to an external operation circuit (relaysequence) and the main power to the inverter isgenerally cut off at a power failure, the operationcommand issued to the inverter is also cut off. Thisfunction sets the time an operation command is to beheld in the inverter. If a power failure lasts beyond theself-hold time, power-off is assumed, automatic restartmode is released, and the inverter starts operation atnormal mode when power is applied again.

OperationamountDeviationOperationamountDeviationH22H23H24These functions are not generally used alone but arecombined like P control, PI control, PD control, and PIDcontrol.P operationOperation using an operation amount (output frequency)proportional to deviation is called P operation, whichoutputs an operation amount proportional to deviation,though it cannot eliminate deviation alone.DeviationPID control (P-gain)PID control (I-gain)PID control (D-gain)D operationAn operation where the operation amount (outputfrequency) is proportional to the deviation differential iscalled a D operation, which outputs an operation amountas the deviation differential and, therefore, is capable ofresponding to sudden changes.TimeTimeOperationamountH 2 2 P - G A I NSetting range: 0.01 to 10.0 timesP (gain) is the parameter that determines the responselevel for the deviation of P operation. Although anincrease in gain speeds up response, an excessive gaincauses vibration, and a decrease in gain delays response.The value "1" is the P(gain) that is when the maximumfrequency 100% at deviation 100%.ResponseTime I operationAn operation where the change speed of the operationamount (output frequency) is proportional to thedeviation is called an I operation. An I operationoutputs an operation amount as the integral of deviationand, therefore, has the effect of matching the controlamount (feedback amount) to the target value (e.g., setfrequency), though it deteriorates response for significantchanges in deviation.H 2 3 I - G A I NTimeSetting range: 0.0 (Inactive), 0.1 to 3600 seconds"H23 I-gain" is used as a parameter to determine the effectof I operation. A longer integration time delays responseand weakens resistance to external elements. A shorterintegration time speeds up response, but an integrationtime that is too short causes vibration.H 2 4 D - G A I NSetting range: 0.00 (Inactive), 0.01 to 10.0 seconds"H24 D-gain" is used as a parameter to determine theeffect of a D operation. A longer differentiation timecauses vibration by P operation quickly attenuating at theoccurrence of deviation. Excessive differentiation timecould cause vibration. Shortening the differentiationtime reduces attenuation at the occurrence of deviation.PI controlP operation alone does not remove deviation completely.P + I control (where I operation is added to P operation)is normally used to remove the remaining deviation. PIcontrol always operates to eliminate deviation even whenthe target value is changed or there is a constantdisturbance. When I operation is strengthened,however, the response for rapidly changing deviationdeteriorates. P operation can also be used individuallyfor loads containing an integral element. PD controlIf deviation occurs under PD control, an operationamount larger than that of D operation alone occursrapidly and prevents deviation from expanding. For asmall deviation, P operation is restricted. When theload contains an integral element, P operation alone mayallow responses to vibrate due to the effect of the integralelement, in which case PD control is used to attenuatethe vibration of P operation and stabilize responses. Inother words, this control is applied to loads in processeswithout a braking function.PID controlPID control combines the P operation, the I operationwhich removes deviation, and the D operation whichsuppresses vibration. This control achievesdeviation-free, accurate, and stable responses.Adjusting PID set valueAdjust the PID value while monitoring the responsewaveform on an oscilloscope or other instrument ifpossible. Proceed as follows:-Increase the value of "H22 P-gain" without generatingvibration.- Decrease the value of "H23 I-gain" without generatingvibration.- Increase the value of "H24 D-gain" without generatingvibration.TECO–Westinghouse Motor Company Function Explanation 78

7. Maintenance and InspectionIt is recommended that daily and periodic inspections be carried out to insure trouble-free operationand long-term reliability. The following are recommendations for conducting these inspections.7-1 Daily InspectionDuring operation, a visual inspection for abnormal operation can be completed externally withoutremoving the covers.The inspections should cover the following:(1) The performance is as expected and is within specifications.(2) The environment conforms to the drive specifications.(3) The digital operator is functioning normally.(4) There are no abnormal sounds, vibrations, or odors.(5) There are no indications of overheating or discoloration.7-2 Periodic InspectionsPeriodic inspections are carried out after stopping drive operations, disconnecting the power source,and removing the protective cover(s).• Because the large capacitors in the main DC circuit retain lethal voltage levels after poweris disconnected and take time to discharge, wait at least five minutes after turning off thepower supply for inverter rated at 30HP/CT, 40HP/VT or less, and ten minutes for inverterrated at 40HP/CT, 50HP/VT or more. (Check that the charge lamp (CRG) is off, and thatthe voltage is 25V DC or less between terminals P(+) and N(-). Otherwise, electric shockDANGER or injury may result.• Only authorized personnel should carry out maintenance and component replacementoperations. (Remove metal jewelry such as watches and rings and use insulated tools.)• Never modify the inverter. Otherwise, electric shock or injury may result.Table 7-2-1 Periodic Inspection ListArea to Check Items to Check How to Inspect Evaluation CriteriaEnvironmentDigital operatorStructure(frame & cover)Main circuitCommonConductor andwire1) Check the ambient temperature, humidity,Vibration and atmosphere (dust, gas, oil mist,water drops).2) Is the area surrounding the equipment free offoreign objects?1) Is the display hard to read?2) Are the characters complete?1) Is there abnormal sounds or vibration?2) Are fasteners loose?3) Is there deformation or damage?4) Is there discoloration as a result ofoverheating?5) Are there stains or accumulated dust?1) Are there loose or missing fasteners?2) Is there deformation, cracks, damage, anddiscoloration due to overheating ordeterioration in the equipment and insulation?3) Are there stains and accumulated dust?1) Is there discoloration or distortion of aconductor(s) due to overheating?2) Are there cracks, crazing or discoloration ofthe cable sheath?1) Conduct visualinspection and usethe appropriateequipment.2) Visual inspection.1) Visual inspection.2) Visual inspection.1) Visual and auralInspection.2) Tighten.3) Visual inspection.4) “5) “1) Tighten.2) Visual inspection.3) “1) Visual inspection.2) “1)Results complywith specifications.2) The area is clear.1) The display can beread.2) Characters arecomplete.1) No abnormalities2) “3) “4) “5) “1) No abnormalities2) No abnormalitiesNote: Discolorationof the bus bar does3) not indicate aproblem.1) No abnormalities2) “Cont._______________________________________________________________________TECO – Westinghouse Motor Company Maintenance & Inspection 97

1) Determination of the capacitance of the main circuit capacitors.This inverter is equipped with a function to automatically indicate the capacitance of the capacitors inthe main DC circuit when powering up the drive after disconnecting the power according to theprescribed conditions.The initial capacitance values are set in the inverter when shipped from the factory, and the decreaseratio (%) to those values can be displayed.Use the procedure as next described.(a) Remove any option cards from the inverter. Also disconnect the DC bus connections to the main circuitP(+) and N(-) terminals from the braking unit or other inverters if connected. The existing power-factorcorrecting reactor (DC reactor) does not need to be disconnected.A power supply connected to the auxiliary input terminals (R0, T0) that provides control power should beisolated.(b) Disable all the digital inputs (FWD, REV, X1-X9) on the control terminals. Also disconnect RS485serial communication if used.Turn on the main power supply. Confirm that the cooling fan is rotating and that the inverter is notoperating. (There is no problem if the "OH2 External thermal relay tripped" trip function is activated due tothe digital input terminals being disabled.)(c) Turn the main power off.(d) Turn on the main power again after verifying that the charge lamp is completely off.(e) Open the maintenance information on the digital operator and confirm the capacitance values of thecapacitors.2) Life expectancy of the control PC board.The actual capacitance of a capacitors is not measured in this case. However, the integrated operatinghours of the control power supply multiplied by the life expectancy coefficient defined by thetemperature inside the inverter will be displayed. Hence, the hours displayed may not agree with theactual operating hours depending on the operational environment.Since the integrated hours are counted by unit hours, power input for less than one hour will bedisregarded.3) Life expectancy of cooling fan.The integrated operating hours of the cooling fan are displayed. Since the integrated hours arecounted by unit hours, power input for less than one hour will be disregarded.The displayed value should be considered as a rough estimate because the actual life of a cooling fanis influenced significantly by the temperature.Table 7-2-2 Estimate of Life Expectancy Using Maintenance InformationPartsLevel of JudgmentCapacitor in main DC circuit85% or less of the initial valueElectrolytic capacitor oncontrol PC board61,000 hoursCooling fan40,000 hours (5HP or less), 25,000 hours (Over 7.5HP/CT,10HP/CT) (*1)*1 Estimated life expectancy of the cooling fan at inverter ambient temperature of 40°C (104°F)_______________________________________________________________________TECO – Westinghouse Motor Company Caps, Control Board & Cooling Fan Life Expectancy 99

EQ5 AC Drive Operations Manual7-3 Main Circuit Voltage, Current, and Power Measurements.When making main circuit voltage and current measurements, the resulting values depend on the typeof meter used due to the harmonic component included in the voltage and current of the main circuitpower (input) and the output (motor) side of the inverter. When measuring with a meter forcommercial power frequency, use the meters shown in Table 7-3-1.The power-factor cannot be measured directly using power-factor meters commercially available atpresent on the market, which measure the phase difference between voltage and current. Whenpower-factors must be measured, measure the power, voltage, and current on both the input side andoutput side, then calculate the power-factor using the following formula:P o w e r[W]P o w e r − f a c t o r =× 10 0[%]3 × V o l t a g e[V]× C u r r e n t[A]Table 7-3-1 Meters Used for measuring Main Circuit ValuesInput (power supply) SideOutput (motor) SideVoltage Current* Voltage CurrentDC LinkCircuitVoltage(P(+) - N(-))ItemMeternameMetertypeAmmeterA R,S,TMovingirontypeVoltmeterV R,S,TRectifieror movingirontypePowermeterW R,S,TDigital powermeterAmmeterA U,V,WMovingirontypeVoltmeterV U,V,WRectifiertypePowermeterW U,V,WDigital powermeterDC voltmeterVMoving-coiltypeSymbolNote: When measuring the output voltage using a rectifier type meter, an error may occur.Use a digital AC power meter to ensure accuracy.Meter Placement Diagram_______________________________________________________________________TECO – Westinghouse Motor Company Main Circuit Voltage, Current & Power Measurements 101

EQ5 AC Drive Operations Manual7- 4 Insulation TestIt is not necessary to do an insulation test on the inverter as this was completed at the factory. If aninsulation test with a megger test must be completed, then proceed as described below as anincorrect testing method may result in product damage.If a dielectric strength test must be completed, the specifications for the test must be followed asImproper testing may result in damage to the inverter. Please contact your local distributor or nearestTWMC sales office for further guidance.(1) Megger test for the main power circuit.a - Use a 500V DC type megger and isolate the main power before commencing measurement.b - If the test voltage is connected to the control circuit, remove all connection cables to the controlcircuit.c - Connect the main circuit terminals together using common cables as shown in Fig. 7-4-1.d - Perform the megger test only between the common cables connected to the main circuit and theground (terminal G).e - A megger indicating a reading of 5MΩ or more is normal. (This is the value measured with onlythe inverter connected.)Fig. 7-4-1 Main Circuit Insulation Test(2) Insulation test in the control circuit.A megger test and a dielectric strength test must not be performed on the control circuit or damagewill result. To test the control circuit, use a high resistance range multimeter and proceed as follows.a - Remove all external cables from the control circuit terminals.b - Conduct a continuity test between the isolated control circuit grounds. A result of 1MΩ or more isnormal.(3) Exterior main circuit and sequence control circuit.Remove all cables from inverter terminals to ensure the test voltage is not applied to the inverter.7-5 Parts ReplacementThe life expectancy of a part depends on the type of part, the environment, and usageconditions. Parts should be replaced as shown in Table 7-5-1 Parts Replacement.Table 7-5-1 Parts ReplacementPart NameStandard Period forReplacementCommentsCooling fan 3 years Exchange for a new part.Smoothing capacitor 5 yearsExchange for a new part (determineafter checking).Electrolytic capacitorExchange for a new PC board7 yearson the PC board(determine after checking).Fuse 10 years Exchange for a new part.Other parts - Determine after checking.______________________________________________________________________TECO – Westinghouse Motor Company Insulation Testing &Parts Replacement 102

EQ5 AC Drive Operations Manual9. OptionsThe inverter supports two internally mounted cards. One option card is mounted under the main cover(Location A) and the other option card is mounted in a special adapter under the keypad (Location B).Only one card can be mounted in these locations. There are two different types of option cards, Type 1and Type 2. You cannot use two Type 1 or Two Type 2 cards but you can mix any combination of Type1 and Type 2 provided you only have one option per mounting location. Each option card must bemounted in the designated location.

EQ5 AC Drive Operations Manual10. Electromagnetic Compatibility (EMC)10-1 GeneralIn accordance with the provisions described in the European Commission Guidelines Document onCouncil Directive 89/336/EEC, the EQ5 series of inverters is chosen to be classified as "ComplexComponents". Classification as a "Complex Components" allows a product to be treated as an"apparatus", and thus permits compliance with the essential requirements of the EMC Directive to bedemonstrated to both an integrator of EQ5 Inverters and to his customer or the installer and theuser.EQ5 Inverters are supplied `CE-marked', signifying compliance with EC Directive 89/336/EEC whenused with a specified filter installed and grounded in accordance with this sheet. This Specificationrequires the following performance criteria to be met.EMC product standard EN61800-3/1997 +A11/2000Immunity : Second environment ( Industrial environment )Emission : First environment ( Domestic environment )Distribution class of Emission:Unrestricted DistributionRestricted DistributionEQ5-4025-C or less. Without Options installed (See Sec. 9)Without Options installed EQ5-4025-C or more.(See Sec. 9)EQ5-2XXX-CWith Options installed (See Sec. 9)EQ5-2XXX-C / EQ5-4XXX-C all models with any of the following options.Card option :OPC-G11S-AIO, DIO, RY, PGDIO,PGRY, TLBus option :OPC-G11S-PDP, DEV, MBP, IBS, COPWARNINGThis is a product of the restricted sales distribution class according toIEC61800-3.In a domestic environment this product may cause radio interference inwhich case the user may be required to take adequate measures.Note: It is customer’s responsibility to check whether the equipment conforms to EMC directive.10-2 Recommended Installation InstructionsIt order to conform to the EMC Directive, these instructions must be followed. Please followall safety procedures when working with electrical equipment. All electrical connections to thefilter, Inverter and motor must be made by a qualified electrical technician.1) Use the correct filter according to Table 10-2-1.2) Install the Inverter and filter in an electrically shielded metal enclosure.3) The back panel of the enclosure should be prepared for the mounting of the filter. Care should betaken to remove any paint etc. from the mounting holes and surface area of the panel to ensurethe best possible grounding of the filter and other components.4) Use shielded cable for the control, motor and other wiring connected to the Inverter, and properlyground the shields. (See Fig. 10-2-5)5) It is important that all wire lengths are kept as short as possible and that incoming power andoutgoing motor cables are kept well separated.Note: To minimize the conducted radio disturbance in the power distribution system, the length of themotor-cable should be as short as possible._________________________________________________________________________TECO – Westinghouse Motor Company EMC Compatibility 121
