The installation safety precautions for the TOSHIBA P3 435K are:

Always ground the unit to prevent electrical shock and to help reduce electrical noise. A separate ground cable should be run inside the conduit with the input, output, and control power cables (See Grounding page 4-7). THE METAL OF CONDUIT IS NOT AN ACCEPTABLE GROUND.

Only qualified personnel should install this equipment (see General Safety Instructions on page iii).

Installation of drive systems should conform as a minimum, to the 1999 NEC National Electrical Code Article 110 “Requirements For Electrical Installations”, to all regulations of the Occupational Safety and Health Administration, and to any other applicable national, regional or industry codes and standards.

Install in a secure and upright position in a well ventilated location that is out of direct sunlight. The ambient temperature should be between -10 deg C and 40 deg C.

Allow clearance space to insure adequate ventilation. Do not obstruct any of the ventilation openings.

Avoid installation in areas where vibration, heat, humidity, dust, fibers, steel particles, explosive mists, gasses or sources of electrical noise are present.

Adequate working space and illumination must be provided for adjustment, inspection and maintenance of the drive (see 1999 NEC Article 110-16).

A noncombustible insulating floor or mat should be provided in the area immediately surrounding the electrical system where maintenance is required.

Use lockout/tagout procedures on branch circuit disconnect before drive installation.

Connect three phase power of the correct voltage to input terminals L 1, L2, L3 (R, S, T) and connect three phase power from output terminals T1, T2, T3 (U, V, W) to a motor of the correct voltage and type for the application. Size the branch circuit conductors in accordance with Selection of Main Circuit Wiring Equipment and Standard Cable Sizes Page 4-2.

If conductors of a smaller than recommended size are used in parallel to share current then the conductors should be kept together in sets i.e. U1, V1, W1 in one conduit and U2, V2, W2 in another (see 1999 NEC Article 300-20 and Article 310-4). National and local electrical codes should be checked for possible cable derating factors if more than three power conductors are run in the same conduit (see 1999 NEC Article 310 adjustment factors on page 70-196).

Install a molded case circuit breaker (MCCB) between the power source and the inverter. Size the MCCB to clear the available fault current of the power source (see 1999 NEC Article 430 Article 102 through Article 111).

Use separate metal conduits for routing the input power, output power, and control circuits.

If the factory provided door or NEMA 1 enclosure is removed from the drive, then it must be provided with an alternate enclosure before operating. The alternate enclosure should be a minimum of NEMA 1.

Do not connect control circuit terminal block return connections marked CC to inverter earth ground terminals marked GND(E). See Standard Connection Diagrams page 4-1 and Terminal Connections and Functions page 5-3.

If a secondary Magnetic Contactor (MC) is used between the inverter output and the load, it should be interlocked so the ST-CC terminals are disconnected before the output contactor is opened. If the output contactor is used for bypass operation, it must also be interlocked so that commercial power is never applied to the inverter output terminals (U,V,W).

Power factor improvement capacitors or surge absorbers must not be installed on the inverter’s output.

The operating safety precautions for the TOSHIBA P3 435K are:

Do not touch any internal part with power applied to the inverter; first remove the power supply from the drive and wait until charge LED (see page 5-1 for location) is no longer illuminated. Charged capacitors can present a hazard even if source power is removed.

DO NOT OPERATE THIS UNIT WITH ITS CABINET DOOR OPEN.

Only qualified personnel should have access to the adjustments and operation of this equipment. They should be familiar with the drive operating instructions and with the machinery being driven.

Only properly trained and qualified personnel should be allowed to service this equipment. See page iii.

Follow all warnings and precautions. Do not exceed equipment ratings.

Do not power up the inverter until this entire operation manual is reviewed.

The input voltage must be within +/-10% of the specified input Voltage. Voltages outside of this permissible tolerance range may cause internal protection devices to turn on or can cause damage to the unit. Also, the input frequency should be within +/-2 Hz of the specified input frequency.

Do not use this inverter with a motor whose rated input is greater than the rated inverter output.

This inverter is designed to operate NEMA B motors. Consult the factory before using the inverter for special applications such as an explosion proof motor or one with a repetitive type piston load.

Do not apply commercial power to the output terminals T1 (U), T2 (V), or T3 (W) even if the inverter source power is off. Disconnect the inverter from the motor before megging or applying bypass voltage to the motor.

Interface problems can occur when this drive is used in conjunction with some types of process controllers. Signal isolation may be required to prevent controller and/or drive malfunction (contact Toshiba or the process controller manufacturer for additional information about compatibility and signal isolation).

Do not open and then re-close a secondary magnetic contactor (MC) between the drive and the load unless the drive is OFF (output frequency has dropped to zero) and the motor is not rotating. Abrupt re-application of the load while drive is on or while motor is rotating can cause drive damage.

Use caution when setting output frequency. Overspeeding a motor can decrease its torque-developing ability and can result in damage to the motor and/or driven equipment.

Use caution when setting the acceleration and deceleration time. Unnecessarily short times can cause tripping of the drive and mechanical stress to loads.

The following final checks should be made before applying power to the TOSHIBA P3 435K unit:

Confirm that source power is connected to terminals L 1, L2, L3 (R, S, T). Connection of incoming source power to any other terminals will damage the drive.

The 3-phase source power should be within the correct voltage and frequency tolerances.

The motor leads must be connected to terminals T1, T2, T3 (U, V, W).

Make sure there are no short circuits or inadvertent grounds and tighten any loose connector terminal screws.

Prior to releasing an electrical drive system for regular operation after installation, the system should be given a start-up test by qualified personnel. This assures correct operation of the equipment for reasons of reliable and safe performance. It is important to make arrangements for such a check and that time is allowed for it.

When power is applied for the first time, the drive automatically starts up in the frequency monitor function of standard monitor mode with the ‘default’ parameters set as shown in the “FACTORY SETTING” column of the parameter tables starting on page 8-1. If these settings are not optimal for the application, program the desired settings before initiating a run. The drive can be operated with no motor connected. Operation with no motor connected or use with a small trial motor is recommended for initial adjustment or for learning to adjust and operate the drive.

The following maintenance should be performed on the TOSHIBA P3 435K:

Use power lockout/tagout procedures on the disconnecting means in accordance with applicable electrical codes (see 1999 NEC Article 430-101) before performing any drive maintenance.

Periodically check the operating drive for cleanliness.

Do not use liquid cleaning agents.

Keep the heatsink free of dust and debris.

Periodically check electrical connections for tightness (with power off, locked out, and with charge LED extinguished (see page 5-1 for location)).

Operating mode switching anytime (it is not necessary to stop the drive) is performed with the LOCAL/REMOTE and MANUAL/AUTO keys.

When power is applied to an inverter, if the command mode selection is not changed from its default setting, the drive will default to terminal (frequency and run/stop) control mode. To change from local frequency control to remote frequency control, or vice versa, press the UR key.

CAUTION: If the inverter is running at 0 Hz, and the Local/Remote key is pushed, the frequency command input will be switched to a source that may be set for a non-zero frequency command, and the motor may begin turning without any other key pressed.

Run/stop commands from the LED operation panel are valid for the following settings of the CMOD parameter (O=permissible, X=not permissible):

Run/stop commands are entered with the RUN and STOP keys.

In auto mode, the emergency off command is executed with the following procedure (assume starting in terminal control mode with the inverter running):

The first time STOP/RESET key is pressed, emergency off command prompt “ECIFF” will be displayed.

If within two seconds, the STOP/RESET key is pressed a second time, the emergency off command will be issued with “E” displayed.

If within two seconds, STOP/RESET is not pressed a second time, the emergency off command will be aborted and the display will return to the standard monitor mode.

In manual mode, the emergency off command is similar with that of auto mode. The first time STOP/RESET key is pressed, it will be treated as a regular stop command. Therefore, there is no “ECIFF” display.

If STOP/RESET key is pressed a second time within one second, the press will be treated as emergency off command and E will be displayed and will be continuously flashing.

If STOP/RESET key is not pressed within one second, no emergency off command will be issued.

A trip clear can be performed after the cause of the trip has been removed by using the following procedure:

When STOP/RESET is pressed the trip is cleared and the display returns to standard monitor mode.

If any key other than the STOP/RESET key is pressed at the trip clear command prompt, the trip clear command is aborted and the display returns to standard monitor mode (where the trip title will be displayed flashing). The trip clear command does not clear the recorded past faults.

The TYP parameter for Standard Setting Selections on the TOSHIBA P3 435K has the following options:

TYP = 0: No effect

TYP = 1: 50Hz standard operation, maximum output frequency, base frequencies, upper limit frequency, all terminal input reference point #2 frequencies, and commercial power/inverter switching frequency are set for 50Hz operation.

TYP = 2: 60Hz standard operation, maximum output frequency, base frequencies, upper limit frequency, all terminal input reference point #2 frequencies, and commercial power/inverter switching frequency are set for 60Hz operation.

TYP = 3: Standard factory-shipped conditions (sets all parameters except those in Gr.Rn to their factory-shipped values). THIS CLEARS ALL PAST TRIPS.

TYP = 4: Trip history clear (only past trips are cleared)

TYP = 5: Saves user-set parameters

TYP = 6: Standard user-set conditions (sets all parameters to the user saved settings)

TYP = 7: Initialize inverter typeform (Used to reset a ECLJP error.)

When the ree parameter is set to a value not equal to zero on the TOSHIBA P3 435K, if an overcurrent, overvoltage, or overload trip occurs during operation, the inverter will trip, and the retry sequence will begin. The retry sequence will repeatedly attempt to restart the motor, and if normal operation can be achieved and last for one second, the inverter will switch to standard monitor mode, and operation will continue from there. However, if within the set number of retry attempts, the inverter cannot be restarted, it will remain tripped, and the standard trip message will be shown.

The Damper function on the TOSHIBA P3 435K is selected by both assigning code 55 (damper status input 0:damper closes, 1:damper open) to an input terminal and assigning 64 or 65 (open damper 64/65: positive/negative logic) to an output terminal. Unless both are assigned, the damper function will not work.

If “damper status” is assigned to an input terminal and “open damper” is assigned to an output terminal, damper will work in the following way:

Whenever a run command is issued, “open damper” signal is sent out to the assigned output terminal. A wait occurs until “damper status” changes to 1 (means damper open full) and motor turns on. If a stop command is issued, “open damper” will be cleared (means to close damper) after the motor stops. During a deceleration, if another run command is issued, the motor should run immediately because the damper is still open. If “damper status” input becomes 0 (means the damper closes) while the motor is running, it drive trips and flashes “dRnp”. The damper trip is non-retriable. If any inverter trip occurs, after motor stops, the damper will be closed.

The Fire speed Function on the TOSHIBA P3 435K is used to automatically start a motor at the preset speed and forward direction in case of fire. If fire status input is assigned to an input terminal (default assignment to S1 input terminal) and the inverter is not in trip, then whenever fire is detected, a run command at forward direction and the speed set by Item 131 (F5or) will be issued. Fire speed run command has the highest priority besides drive trip. In a fire situation, the motor can not be stopped by STOP command from anywhere. Before the fire signal goes off, the motor can only be stopped by a drive trip. If the fire signal is not cleared, after trip is cleared, the motor automatically will start to run again at fire speed. If any trip occurs, the motor will stop. Remember that the fire speed run command is only a run command but with the highest priority. If the damper function is also working, after the fire speed run command is issued, the first thing to do is to open the damper. The motor will not run until a “damper open full” signal is received.

Fire speed is selected by default. The default setting for fire status input is input terminal S1. The fire status input can be assigned to any input terminal by setting input terminal function to code 56. Fire speed can be set by Item 131 (F5or). Fire speed is limited by setting the upper and lower limit frequency in Item 4 (LL) and Item 3 (UL.)

The following programming example is for Preset Speed on the TOSHIBA P3 435K:

This example uses “S1” and “S2” terminals to access three preset speeds of 11.0 Hz (close “S1”-“CC”), 55.0 Hz (close “S2”-“CC”), and 33.7 Hz (close “S1” and “S2” to “CC”). “F”-“CC” and “ST”-“CC” must be made on the drive’s terminal strip. This example assumes Input terminal 1 II:: 1=1 and Input terminal 2 II::2 = 2 prior to performing the following programming.

This example uses the “RX” terminal to trim a reference (i.e. a 4-20 mA input) +/-5 Hz on the TOSHIBA P3 435K:

The following programming allows a drive to emulate motor operated pot control. Momentarily shorting “S1”-“CC” increases frequency reference. Momentarily shorting “S2”-“CC” decreases frequency reference. Momentarily shorting “S3”-“CC” erases frequency reference. “F”-“CC” and “ST”-“CC” must be made on the drive’s terminal strip. This example assumes drive is defaulted to factory settings prior to the following programming is done:

These parameters must be adjusted to use TTC with a TOSHIBA/HOUSTON motor on the TOSHIBA P3 435K:

* Enter appropriate value from motor’s nameplate. KW = 0.746 X HP.

** Enter “0” for an EQPIII or “1” for a high efficiency motor.

The following parameters must be adjusted to use TTC for a GENERIC motor on the TOSHIBA P3 435K:

* Enter appropriate value from motor’s nameplate. KW = 0.746 X HP.

** Enter “0” for an EQPIII or “1” for a high efficiency motor.

**** The drive will auto tune the next time a run is initiated. This parameter is then reset to “0” by the drive’.

* Retryable faults include: OVERCURRENT(ACCEL) IJ[ I, OVERCURRENT(DECEL) IJ[2, OVERCURRENT(RUN) IJ[3, DC OVERCURENT(ACC) IJ[ IP, DC OVERCURRENT (DEC) IJ[2P, DC OVERCURRENT(RUN) IJ[3P, OVERVOLTAGE(ACCEL) IJP I, OVERVOLTAGE(DECEL) IJP2, OVERVOLTAGE(RUN) IJP3, OVERHEAT IJH, MOTOR OVERLOAD IJLilc, INVERTER OVERLOAD IJL In, DBR OVERLOAD TRIP IJLr

For OVERCURRENT (ACCEL) D[ i or DC OVERCURRENT (ACC) D[ iP on the TOSHIBA P3 435K:

Cause: Drive current exceeded 145% of its rated FLA (190% above 100 HP).

Comments: Check for phase-phase short. ACCELERATION TIME R[[ i or R[[2 may be too small. VOLTAGE BOOST Lib i or Llb2 may be too high. Is motor/machine jammed? Is mechanical brake engaged while drive is running? If drive is starting into a rotating motor, see Item 176, AUTO-RESTART RrSc . If there is a contactor between motor and drive, wire so that contactor changes state only when drive is outputting 0.0 Hz. Drive will automatically adjust accel time with Item 30, ACC/DEC PATTERN #1 S[LI i set to option “1”.

For OVERCURRENT (DECEL) D[2 or DC OVERCURRENT (DEC) D[2P on the TOSHIBA P3 435K:

Cause: Drive current exceeded 145% of its rated FLA.

Comments: Check for phase-phase short. DECELERATION TIME dEC i or dE[2 may be too small. Is motor/machine jammed? Is mechanical brake engaged while drive is running? Adding appropriate braking resistor across “PA” and “PB” terminals may solve problem (see page 9-20). Drive will automatically adjust decel time with Item 30, ACC/DEC PATTERN #1 S[LI i option set to “1”.

For OVERCURRENT (RUN) D[3 or DC OVERCURRENT (RUN) D[3P on the TOSHIBA P3 435K:

Cause: Drive current exceeded 145% of its rated FLA.

Comments: Check for phase-phase short. Is motor/machine jammed? Is mechanical brake engaged while drive is running? Adding appropriate dynamic braking resistor across “PA” and “PB” terminals may solve problem (see page 9-20). If there are severe load fluctuations, adding mechanical dampening or an output line reactor may help to electrically dampen.

For U-PHASE SHORT-CIRCUIT OCR I or V PHASE SHORT-CIRCUIT O[R2 or W PHASE SHORT-CIRCUIT O[R3 on the TOSHIBA P3 435K:

Cause: Drive detected short-circuit in transistor.

Comments: Replace transistor. Contact your Toshiba distributor for authorized repair.

For LOAD-END OVERCURRENT O[l on the TOSHIBA P3 435K:

Cause: Drive detected short-circuit on output.

Comments: Check for phase-phase short. Meg motor/leads with leads disconnected from drive. Remove any power factor correction caps on motor. See Item 169, OUTPUT SHORT CIRCUIT DETECTION SELECT.

For OVERVOLTAGE (ACCEL) OP I or OVERVOLTAGE (RUN) O[P3 on the TOSHIBA P3 435K:

Cause: Bus exceeded 787 VDC (460 volt drive).

Comments: Incoming AC may have gone high or spiked (verify with Item 319,320, 321, or 322 set to option “16”); a line reactor or a lower tap on transformer may help. Motor may be mechanically forced to run faster than drive is commanding; install appropriate dynamic braking resistor (see page 9-20). On eccentric cyclic loads like presses or pump jacks, contact your Toshiba distributor for special programming instructions that may make a DBR unnecessary.

For OVERVOLTAGE (DEC) O[P2 on the TOSHIBA P3 435K:

Cause: Bus exceeded 787 VDC (460 volt drive).

Comments: Incoming AC may have gone high or spiked (verify with Item 319 set to option “16”); a line reactor or a lower tap on transformer may help. Item 2, DECELERATION TIME #1 O[P2 may be too short. Drive will automatically change decel time with Item 31, ACC/DEC PATTERN ADJUST LOW 5[l option set to “1 “. Make sure Item 164, OVERVOLTAGE STALL PROTECTION OP55 is set to option “0”. Motor may be mechanically forced to run faster than drive is commanding (due to large load inertias mechanical couplings); install appropriate dynamic braking resistor (see page 9-20). On eccentric cyclic loads like presses or pump jacks, contact your Toshiba distributor for special programming instructions that may make a DBR unnecessary.

For INVERTER OVERLOAD Ol In on the TOSHIBA P3 435K:

Cause: Drive exceeded 100% of its rated current for too long of a time.

Comments: This trip indicates that the drive output exceeded its rated current for specific amounts of time. For example, drives can output 110% of their rated current for 60 seconds, and 150% for 0.5 seconds. If using DC Injection, Item 166, DC INJECTION CURRENT db[ or Item 167 DC INJECTION TIME dbe they may be too large. If Item 98, PWM CARRIER FREQUENCY [F is greater than 8 KHz, try carrier frequencies less than 8 KHz. Programming Item 14, OVER LOAD SELECTION Oln to option”1″ or “3” (soft stall on) makes the drive reduce output frequency/voltage to shed load (works best on variable torque applications). Motor or load bearings may have seized. Enabling True Torque Control (see page 1 0-7) may reduce drive’s current output and solve the problem. Make sure that drive is seeing voltage on all three input phases. Drive may be undersized.

For MOTOR OVERLOAD Olile on the TOSHIBA P3 435K:

Cause: Motor is in danger of overheating because it drew too much current for too long of a time, as determined by the drive.

Comments: See page 8-14. Check Items 178, 179, 180, and 181. If trip occurred at a low frequency, the setting of Item 179, OVERLOAD REDUCTION START FREQUENCY OlF is probably critical. Motor overload protection can be turned off by placing a “2” or “3” in Item 181. Check value in Item 180, MOTOR 110% OVERLOAD TIME LIMIT Ole.

For DBR OVERCURRENT 0[,- on the TOSHIBA P3 435K:

Cause: IGBT7 (dynamic braking transistor) is damaged

Comments: Check ohm value connected to “PA” and “PB” terminals (see page 9-20 for minimum ohm values). If using multiple resistors, make sure parallel-series combination is wired correctly. Check IGBT7. Check DC bus fuse for continuity; if open, check output transistors. Consult your Toshiba distributor for authorized service.

For DBR OVERLOAD OL,- on the TOSHIBA P3 435K:

Cause: Dynamic braking resistor is in danger of overheating (as determined by drive).

Comments: Check that the values entered into Item 162, BRAKING RESISTOR VALUE Pbr and Item 163, BRAKING RESISTOR CAPACITY Pb[P are correct.

For OVERHEAT OH on the TOSHIBA P3 435K:

Cause: Drive’s heatsink exceeded 90deg C.

Comments: Check drive’s muffin fans (if any). Clear heatsinks of anything blocking airflow. The enclosure that the drive is installed in may be too small or there may be to many heat sources in the same enclosure. Drive may not have been properly sized for operating altitude. Thermistor on heatsink may be bad.

The causes for EMERGENCY OFF E on the TOSHIBA P3 435K are:

Drive received one of the following ESTOP commands:

1. Drive was receiving STOP/RUN command via terminal strip when STOP button on keypad was pressed.

2. One of the drive’s input terminal’s function is set to “10” (see Item codes 0-56 and page 9-11), and terminal is being opened/closed to command ESTOP.

For EEPROM WRITE FAILURE or EEPROM READ FAILURE (EEP:, EEP2) on the TOSHIBA P3 435K:

Cause: EEPROM was unable to read/write to peripherals.

Comments: Check for miswiring that may be causing noise (such as “CC” connected to ground, an external 10 volt source connected to “PP” etc.) Control board may need to be replaced. See picture of board on page 5-2.

For RAM ERROR or ROM ERROR (Err3, Err4) on the TOSHIBA P3 435K:

Comments: Check for miswiring that may be causing noise (such as “CC” connected to ground, an external 10 volt source connected to “PP” etc.). Replace control board. See picture of board on page 5-2.

For OPTION ROM ERROR Err5 on the TOSHIBA P3 435K:

Comments: Check for miswiring that may be causing noise (such as “CC” connected to ground, an external 10 volt source connected to “PP” etc.). If drive is energized with option ROM installed and is later energized without option ROM installed, this fault will appear. Reset in normal fashion.

For CPU ERROR ErrY on the TOSHIBA P3 435K:

Comments: If option ROM or option board is installed or removed when drive is powered, this fault will appear. Reset like any fault. Check for miswiring that may be causing noise (such as “CC” connected to ground, an external 10 volt source connected to “PP” etc.). If the CPU is truly damaged, the fault will not reset and replacement of the control board is necessary. See picture of control board on page 5-2.

For COMMUNICATION ERROR ErrS on the TOSHIBA P3 435K:

Cause: RS232 or RS485 timer did not respond

Comments: Check wiring to RS232 or RS485 ports. Check setting of Item 286, COMMUNICATION SELECTION OPt (should be option “1” for RS485). Check jumpers J1, J2, and J3 on RS485 option board (see RS485 Communications Option Manual). Cable may be broken.

For OPTION PCB ERROR Err8 on the TOSHIBA P3 435K:

Comments: If drive is energized with an option board installed and is later energized without the board installed, this fault will appear. Check connectors between control board and option board. Check settings of Item 99, FREQUENCY PRIORITY SELECTION #1 F[ I, Item 100, FREQUENCY PRIORITY SELECTION #2 F[2, and Item 286, COMMUNICATION SELECTION DPe. Use stand-ofts to secure board.

For LOW CURRENT TRIP LI[ on the TOSHIBA P3 435K:

Cause: The drive’s output current went below the current value entered in Item 186, LOW CURRENT DETECT LEVEL LLP[ for at least the amount of time entered in Item 187, LOW CURRENT DETECTION TIME LLPe.

For UNDERVOLTAGE TRIP LIP I on the TOSHIBA P3 435K:

Cause: The drive’s DC bus voltage went below 413 VDC (460 V P3), for at least the time entered in Item 185, UNDERVOLTAGE DETECT TIME LlPe.

Comments: Item 184, UNDERVOLTAGE TRIP SELECTION LlP5L turns the ability to undervoltage trip on/off. On some models, turning on Item 174, REGENERATION POWER RIDE-THROUGH LlLI[ and adjusting Item 175, REGENERATION RIDE-THROUGH TIME LILIa may keep bus up during brown out if there is sufficient regen energy from the load.

For OVERTORQUE TRIP Dc on the TOSHIBA P3 435K:

Cause: The drive’s torque current went above the current value programmed in Item 190, OVERTORQUE TRIP LEVEL DeL. The drive can be programmed to torque current limit; contact your Toshiba distributor and request the torque limit application guideline.

For EARTH FAULT (SOFT) EF I, EARTH FAULT (HARD) EF2 on the TOSHIBA P3 435K:

Cause: Drive detected some current to ground. Depending on rating, drive senses ground fault via ZCT (hard fault) or HCT (soft fault).

Comments: With leads disconnected from drive, meg motor and leads. Look for any moisture that may provide current path to ground. Make sure that control wiring is separated from power wiring. Adding noise supressors on coils of starters on same line as drive may snub noise picked up by ZCT. RF/EMI filter may help remove noise generated by SCR rectifiers in the vicinity. Make sure drive chassis and motor are grounded.

For AUTO-TUNING ERROR Een on the TOSHIBA P3 435K:

Cause: Motor’s physical characteristics are not within the window of allowable values for modeling.

Comments: Try a different inertia setting in Item 353, LOAD MOMENT OF INERTIA ile.IH. Motor must be at rest to perform auto-tuning. Motor must be one HP size within the drive’s HP size. Auto-tuning is best done with motor at full-load temperature (if temperature is very cold, auto-tune error may appear).

For GATE ARRAY FAULT Err5 on the TOSHIBA P3 435K:

Comments: Replace control board.

For CURRENT DETECT ERROR Errl on the TOSHIBA P3 435K:

Comments: Occurs when drive is stopped but CPU detects current flowing. This fault could be caused by plugging in RS232 cable with drive powered (resulting in damage to control board). Adding a RF/EMI filter may remove noise spikes from nearby SCR rectifiers. If the control board is damaged, the drive must be serviced.

For INV TYPEFORM ERROR Ee~P on the TOSHIBA P3 435K:

Cause: Control board is not configured to drive’s rating.

Comments: Enter option “7” into Item 310, STANDARD SETTING MODE SELECTION e~P.

For DAMPER TRIP dRnp on the TOSHIBA P3 435K:

Cause: Damper function is selected (one input terminal is assigned to 56 and one output terminal is assigned to 64). Every time a run command is issued, the output terminal will output a signal to open damper. Then waiting for the damper open full signal from the input terminal. After getting the damper open full signal from the input terminal, the motor will start to run. If the damper is closed while the motor is running, go damper trip.

Comments: Check the input damper status signal.

For IV ANALOG INPUT LOSS TRIP L055 on the TOSHIBA P3 435K:

Cause: L R :5 = 3 and IV input voltage is less than 1 volt.

Comments: Check IV input voltage.

For DC BUS UNDERVOLTAGE nOFF on the TOSHIBA P3 435K:

Cause: The drive’s DC bus voltage went below approximately 413 VDC (460 volt drive), for at least the time entered in Item 184, UNDERVOLTAGE DETECT TIME UPc.

Comments: Item 164, UNDERVOLTAGE TRIP SELECTION turns the ability to undervoltage trip on/off.

For CONTROL POWER LOW POFF on the TOSHIBA P3 435K:

Control Power low warning voltage levels are sensed on DC bus and are set slightly less than DC BUS UNDERVOLTAGE nOFF levels.

For OVERLOAD L on the TOSHIBA P3 435K:

A flashing overcurrent display means that the drive is outputting more than 110% of its rated current. If Item 14, OVERLOAD SELECTION OLn is set to “1” or “3” (soft stall on), the drive’s output frequency will automatically decrease in an effort to reduce current. See suggestions for remedying an inverter overload trip on page 11-4. Setting one of the monitor’s functions (Items 319-322) to “10” will give an indication of how close a drive is to tripping.

For OVERCURRENT [ on the TOSHIBA P3 435K:

A flashing overcurrent display means that the drive is stalling. (Stall level is set by Item 13, STALL PROTECTION CURRENT LEVEL 5EL:). The drive’s output frequency will automatically decrease.

For OVERVOLTAGE P on the TOSHIBA P3 435K:

A flashing overvoltage display means that the drive’s DC bus has exceeded 720 VDC (460 volt drive).

For OVERHEAT H on the TOSHIBA P3 435K:

A flashing overheat display means that the drive’s heat sink temperature has exceeded 84deg C. Display dissappears when heatsink temperature reaches 80deg C.

For COMM c on the TOSHIBA P3 435K:

A flashing comm display means that the drive has momentarily lost communications. Display will clear when follower receives valid reference. Cycling power or reinitializing drive will clear warning.
