System Setup Requirements

• When using the ASD as an integral part of a larger system, it is the responsibility of the ASD installer

or maintenance personnel to ensure that there is a fail-safe in place, i.e., an arrangement desi gned to

switch the system to a safe condition if there is a fault or failure.

• System safety features should be employed and designed into the integrated system in a manner

such that system operation, even in the event of system failure, will not cause harm or result in

personnel injury or system damage (i.e., E-Off, Auto-Restart settings, System Interlocks, etc.).

• The programming setup and system configuration of the ASD may allow it to start the motor

unexpectedly. A familiarity with the Auto-restart settings is a requirement to use this product.

• Improperly designed or improperly installed system interlocks may render the motor unable to start

or stop on command.

• The failure of external or ancillary components may cause intermittent system operation, i.e.; the

system may start the motor without warning.

• There may be thermal or physical properties, or ancillary devices integrated into the overall system

that may allow for the ASD to start the motor without warning. Signs at the equipment installation must

be posted to this effect.

• If a secondary magnetic contactor (MC) is used between the ASD and the load, it should be

interlocked to halt the ASD before the secondary contact opens. If the output contactor is used for

bypass operation, it must be interlocked such that commercial power is never applied to the ASD

output terminals (U, V, and W).

• Power factor improvement capacitors or surge absorbers must not be installed on the output of the

ASD.

• Use of the built-in system protective features is highly recommended (i.e., E-Off, Overload

Protection, etc.).

• The operating controls and system status indicators should be clearly readable and positioned

where the operator can see them without obstruction.

• Additional warnings and notifications shall be posted at the equipment installation location as

deemed required by Qualified Personnel.

- xii -

Operational and Maintenance Precautions

• Turn off, lockout, and tagout the main power, the control power, and instrumentation connections before

inspecting or servicing the drive, or openi n g t he door of the encl os ure.

• Turn off, lockout, and tagout the main power, the control power, and instrumentation connections before

proceeding to disconnect or connect the power wiring to the equipment.

• The capacitors of the ASD maintain a residual charge for a period of time after turning the ASD off. The

required time for each ASD typeform is indicated with a cabinet label and a Charge LED. Wait for at least the

minimum time indicated on the label and ensure that the Charge LED has gone out before openin g the do o r of

the ASD once the ASD power has been turned off.

• Do Not attempt to disassemble, modify, or repair the ASD. Call your Toshiba sales representative for repair

information.

• Do not place any objects inside of the ASD.

• Turn the power on only after attaching (or closing) the front cover and Do Not remove the front cover of the

ASD when the power is on.

• If the ASD should emit smoke or an unusual odor or sound, turn the power off immediately.

• The heat sink and other components may become extremely hot to the touch. Allow the unit to cool before

coming in contact with these items.

• Remove power from the ASD during extended periods of non-use.

• The system should be inspected periodically for damaged or improperly functioning parts, cleanliness, and to

ensure that the connectors are tightened securely.

WARNING

• Ensure that the Run functions (F, R, Preset Speed, etc.) of the ASD are off before performing a Reset. The

post-reset settings may allow the ASD to start unexpectedly.

• In the event of a power failure, the motor may restart after power is restored.

• Retry or Reset settings may allow the motor to start unexpectedly. Warnings to this effect should be clearly

posted near the ASD and motor.

INTRODUCTION

Thank you for purchasing the T300MVi Medium Voltage ASD. This adjustable frequency, solid-state
AC drive features a 3φ input isolation transformer with a 24-pulse converter design, a 32-bit CPU, and a three­unit power module inverter section providing a 5 level output for 4160/3300V drives and 3 level output for
2400V drives. The T300MVi also features as standard, an 8 key Control Panel with a LCD screen and 2
discrete LED lamps to indicate Ready, Run, Local, Remote and Alarm/Fault.

On most power systems, this drive will meet IEEE-519-1992 harmonic regulation guidelines without
installing additional harmonic filters. The input power factor is typically 0.95. The multi-level output produces
a more sinusoidal voltage and reduces stress on the motor winding insul ation. This drive uses high capacity
3300V IGBTs to improve reliability, reduce switching losses, and improve control performance. The PP7
control processor and 6-layer control board achieves high integration and reliability.

- 1

INITIAL COMISSIONING

The drive should be commissioned by qualified personnel only. Below are some general steps

required for commissioning.

CAUTION

Confirmation of Wiring

Make the following final checks before applying power to the unit:

1) Confirm that source power is connected to terminals L1, L2, L3 (R, S, T). Connection of incoming

source power to any other terminals will damage the drive. Other control voltages may be

required. Consult your custom equipment diagrams shipped with the drive for any other

requirements.

2) Verify that the power modules are properly installed and that there was no damage during shipping

or handling.

3) Verify that there are no loose connections or wires and that all of the required shipping split

connections have been made.

4) Verify all external control circuit wiring is complete and properly connected.

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

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

7) Make sure there are no short circuits or inadvertent grounds and tighten any loose connector

terminal screws.

CAUTION

Start-Up and Test

Prior to releasing the drive system for regular operation after installation, the system must be
adjusted and tested 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.

CAUTION

- 2

Cautions on Changing Setting Parameters

The setting data of the T300MVi MV is saved in an EEPROM, non-volatile memory. When the micro
controller initializes at power-up, it reads the EEPROM data and copies it to the RAM (Random Access
Memory). From then on, the micro controller controls the drive using the values in the RAM.

When the setting parameters are changed, by the display-keypad or personal computer ("su pport
tool"), only the execution parameters in RAM are changed. If they need to be stored, they must be manually
written to the EEPROM. Without this operation, the next initialization or power up will cause them to be
replaced by the old data.

When a write to the EEPROM is performed, write processing may take 30 seconds. Turning off the
control power supply during write processing will make both the RAM and EEPROM data abnormal. When the
power is turned on again, this abnormal data will result in an error ("CHECK ERROR") preventing the drive
from running. If such an error occurs, the settings must be reloaded from a saved file. If no setting file exists,
the drive must be re-commissioned.

CAUTION

Do not turn off the control power supply under any circumstances while
writing data to the EEPROM.

- 3

Inspections and Maintenance

Maintenance and inspection is a particularly effective means to help prevent failures an d reduce down
time. Creating equipment specific inspection and maintenance check sheets can help to perform maintenance
and inspection effectively. Detailed inspections and regular maintenance should be carried out in short cycles
initially until a schedule reflecting the site-specific conditions can be determined.

CAUTION

DANGER

Daily Inspections

Daily inspections consist mainly of visual inspections on the following items. These observations
should be made with all of the cubicle doors closed and safety covers installed. Any abnormalities discover ed
should immediately be repaired.

1) Check the temperature, the humidity, the presence of corrosive or explosive gases, and the

presence of dust in the area.

2) Check for any abnormal sound or vibration of the reactor, transformer, or cooling fans.

3) Check for abnormal odors such as the smell of burning insulating materials.

Regular Inspections

Carry out regular inspections with power off, locked out, and with confirmation that the bus v oltage is

completely discharged. Use power lockout/tagout procedure on the disconnecting means in accordan ce

with applicable electrical codes (see 2002 NEC Article 430-101) before perfo rmin g any drive maintenance.

The first thing to do in maintenance and inspection is cleaning. Cleaning should be carried out
according to the conditions of the equipment. Before starting cleaning, turn off the power supply and check
that the main circuit voltage is reduced to 0. Clean dust with a vacuum, dry
cloths. Note that excessive air pressure when blowing out equipment may damage parts and wiring. Do not
use solvents to clean the drive. Substances stuck to the circuits, which cannot be removed by blowing,
should be wiped away using a cloth. As a basic rule, cleaning should start from the upper parts and end at the
lower parts. Cleaning of the lower parts last will allow proper removal of substances that could drop from the
upper parts.

CAUTION

DANGER

Inspections and Maintenance (cont’d)

- 4

Main components

1) Cooling fan - Check to see if there is any abnormality with airflow, increased fan noise, etc.

2) Air filter - Visually check if the air filter is clogged. Gently tap it outside the room to remove loose

dust. To remove caked on dirt use water and a gentle detergent, rinse it with clean water and dry it.

Otherwise replace it with a new one. Cleaning with solvents is not recommended.

3) Main circuit parts and entire cubicle - Check to see if dust is stuck to the cubicl e interior or if there is

any discoloration, heat generation, abnormal sound, leakage, odor or damage with the reactor,

transformer, contactors, cables and connections, fuses, capacitors, lightening arrestors, and resistors.

Check to see that no wires or mounted parts are broken, disconnected, loose or damaged. High

voltage standoffs, insulators, and cable can be cleaned with isopropyl alcohol.

4) Printed Wiring Boards - The boards, which are made up of ICs and electronic components, must be

protected from dust, corrosive gases and extreme temperatures. Pay attention to the installation

environment of the equipment. Regular inspections, the proper cleaning, and maintenance in an

optimal environment is essential for circuit boards. Since most of the components and parts are small

and vulnerable to external forces, when cleaning them, use a brush to carefully wipe off dust. Inspect

the boards for signs of component damage, heating, and corrosion.

Cautions on handling Printed Wiring Boards

a) All maintenance work on the board should be carried out at least 15 minutes after all power
supplies are turned off to allow the capacitors on the boards to discharge.

b) When removing the board, disconnect all the connectors and wires and remove the
mounting screws from the upper part of the board first. At this time, be careful not to drop the
boards or screws. When setting the board down, place it on a static free surface. Be careful
not to damage any components.

c) When attaching the board, do so in the order opposite to the removing procedure. Be sure
that all of the connectors and wires are connected correctly.

d) New boards are shipped in an anti-static bag. Use this bag to store them.

Note that the anti-static coating is only on the inner side of the bag.

4) Check the protection functions for proper operation (Door switches, OH, E-stop...)

5) Check the insulation resistance of the medium voltage circuits.

Recommended Spare Parts

Spare parts are an important part of downtime reduction. When parts in the drive have failed, on-hand
spare parts are necessary to shorten the mean time to repair (MTTR). Since replace m ent of discrete
components is time consuming, it is recommended that entire assemblies be replaced. Recommended spare
parts common to all drives are shown in the following tables. The recommended spare rate and minimum
amount can serve as references for the minimum number of spare parts relative to the total number of drives
on site. It is recommended that the quantity be determined in accordance with the number drives on site.
Many other parts are job specific. It is up to the end user to determine what other parts may be needed.

INTERFACE

Speed sensor

Temperature sensor

The interface between the drive system and external devices is divided into two categori es: power

supply system and control system.

Power Supply Interface and Ground

The power supplies required are the main circuit input of 2400/4160V and (option al) control power

supply of AC480V-60 Hz.

The following figure shows a recommended grounding circuit for the related equipment. Grounding is
intended not only for safety but also to reduce noise problems. The control ground bus is mo unted on
insulated standoffs. It may be separated from the power ground and run separately to the earth ground with
insulated cable if noise problems are encountered with auxiliary control devices.

Grounding must follow local and national codes by attaching a properly sized ground conductor to
the drive equipment.

Motor Interface

If armored and shielded cables are to be used, be sure to connect the shield drain or armor to the
ground bus provided in the drive equipment near the motor terminals (U, V, W). Ensure that the motor is
connected properly at the junction box and properly insulated to protect against accidental shorting or
grounding.

Speed Sensor Interface (Option)

In addition to open loop control, it is also possible to use a speed sensor to perform high precision
speed control. Speed sensor selection explained below

Resolver

The drive is capable of accepting both 1x and 4x resolver feedback. The excitation can be either 1 or
4kHZ. For resolver feedback, the following parameters need to be set:

CS_RES_TYPE=1or4 (Set to match the resolver)

CS_PG_OUT= Set to desired PG output count. (Minimum setting for reslover use is 64)

(See parameter manual for exact settings)

CS_PG_CNT=64

FLG_RES_EX4= 0 for 1kHz, 1 for 4kHz

PG (Pulse Generator)

This drive can only read single ended PG signals. The maximum frequency that the PG input can
read is 10kHz. The PG should be selected so that this limit is never exceeded. It is recommended that a 10%
margin be allowed for overspeed. The following is an example of how to select your PG.

PG pulse count (ppr) = (maximum frequencyx0.9)/ (application top motor speed (min

<Example> When 100% speed is 1800 min

Max PG pulse count = (10000x0.9)/(1800/60) = 300 ppr

Therefore, PG of 300 ppr or less is used.
The following settings should be used:

CS_RES_TYPE=1
CS_PG_OUT=0

CS_PGCNT = 256 (Set to the PPR of the PG.)

Interface (cont’d)
Pulse Signal Output

If a speed sensor is used, speed feedback signals can be output as pul se signals. The PG pulse
output circuit is shown in the following figure. The power supply for the pulses should supplied from an outside
source in a range of 12 V to 24 V. The number of pulses per revolution output can be set using the parameter
CS_PGOUT when a resolver is used. See the parameter setting manual for exact settings. Otherwise, set to
zero when using a PG. With a PG, the number of pulses out equals the number of pulses in. This output is
limited to 10kHz.

The PG pulse output consists of two phases of PGA and PGB at 90° separation. These pulse signals
(at the level of the power supplied from an outside source) are isolated from the control power supply of the
drive through photo-couplers.

Interface (cont’d)
Digital Output

There are 6 programmable digital outputs (DO0-5). DO5 is used internally for control of the input
contactor and should not be changed. The other 5 outputs are available for optional control or indication
functions. These relays can be programmed to any bit in any word in the drive. The most commonly used bits
can be found in the SSEQ_OUT1 and SSEQ_OUT2 words. The word assignment is made via DO0_AS ­DO4_AS parameters. The bit number is set via DO0_BN – DO4BN.

Analog Input

The drive has two general-purpose analog input channels (AIN1, AIN2). They are fixed at ± 10VDC.
The analog signals are converted to digital values through a 12-bit A/D converter. A ±10 Vdc input is
converted to counts by software and is stored in the target data register. Since this signal is directly connected
to the control circuit, it is recommended that an isolation transducer be used. The data register, the gain and
the offset are set with the following parameters:

AIN#_AS Target register – set by symbol name

AIN#_GS Gain setting – defines the number of counts for 10V input

AIN#_OS Offset setting – offsets the input
The "#" of each parameter name denotes the AD channel number. The following figure shows the input ci rcuit:

[Setting examples]

• Example 1: When a 0~8V (0 to 100%) speed reference is input to AIN1.

Set the input jumpers as per the drawings for single ended voltage input.
Set a 0 to 100% (count 0 to 25000) speed reference signal at 0 to +8 V so that it is stored in SP_REF_AIN1.

The input characteristic is shown in the right hand figure.

Set as follows:

AIN1_GS = [25000count x 10v/(10v-2v)] = 31250

AIN1_OS = 0

AIN1_AS = SP_REF_AIN1 or 2

AIN1_TYPE = 1

Input Characteristic Example

Example 2 When a 4~20 mA (0 to 100%) speed reference is input to AIN1, it is recommended
that a 4-20mA/0-10VDC transducer be used. If the source is isolated, a 510Ohm burden resisto r may also be
used. This would give 2V at 4mA. In this case an offset would need to be set in the drive as follows:

AIN1_GS = [25000count x 10v/(10v-2v)] = 31250

AIN1_OS = -[31250counts x 2v/10v] = -6250

AIN1_AS = SP_REF_AIN1 or 2

AIN1_TYPE = 1
When using 4-20mA input and a burden resistor, it is possible that the reference will become negative

if the input falls below 4mA. If this happens, the drive could run in reverse. To stop this, the reverse speed
limit (LMT_SP_R) should be set to zero, if possible. If this can not be done due to the need for reverse jogging,
the parameter LMT_SP_MIN should be set to 0 or higher. This limit fixes the speed reference from the keypad
or the analog inputs to a minimum value.

Analog Output
General-purpose Analog Output

Three channels (AOUT1, 2, and 3) are provided as general-purpose, 610VDC analog output from the
XIO board. These outputs are directly output from the control board. The device reading these signals must
be isolated. To insure this, it is recommended that signal isolators be used. The output can be selected from
a list shown in the parameter setting manual by using the parameters AOUT1-3_CODE. They may also be set
to any function in the drive by the use of the parameters AOUT1-3_OP_AS, AOUT1-3_OP_GS, and AOUT1­3_OP_OS. When using the optional settings, care must be taken to set the output up so that the output signal
does not exceed 610V. Exceeding this value will cause overflow problems.

- 29

Interface (cont’d)
Additional Analog Outputs

Six channels (D/A1 to D/A5 and Amp A) are provided as additional analog outputs. These outputs are
wired out to terminal block TB-AO. Channel A is direct current feedback from the U phase Hall CT. The other
five channels are programmable 610vDC outputs. The data to be output, the gain, and the offset, can be set
from the display/keypad or a personal computer by use of the parameters DA1-5_AS, DA1-5_GS, and DA1­5_OS.

Motor Mounted Fan Circuit

A main motor may require a motor mounted blower fan circuit as an option. When using an external
motor fan, be sure to check the rotation direction of the fan and change its phase rotation if necessary.

You can make a fan interlock for the operation of the drive by connecting an “a” auxiliary contact of the
fan MCCB/starter to one of the digital inputs on the XIO board and programming it as M_FAN.

This function is available in drives with 03C and up software versions only. If the drive has software
version 03A, one of the spare inputs must be used instead.

Main Circuit Configuration

The following circuit shows the configuration of the T300MVi 4160V drive. Input AC is supplied
through an input controller to transformer T1. The transformer has four (4) isolated secondary windings per
output phase, each feeding a 3-phase full wave rectifier bridge. The output of the rectifiers is connected to
three inverter power modules that produce 3-phase AC power at the frequency and voltage required by the
motor.

The AC output voltage of the each inverter power module is 2400V line to neutral. With phase voltages
shifted 120° from one other, an output voltage of 4160V between phases is generated. The output voltage
closely approximates a sine wave. This is shown in the output waveform below. This produces a sine wave

SP_REF1 or SP_REF2 can be used when the drive speed is to be controlled from one location only. When
using local and remote control or there is a need for selection between two separate inputs SP_REF_AIN1
and SP_REF_AIN2 should be used. To select between references, one of the digital inputs should be
programmed as SEL_DI and the selection switch connected.

SP_REF_AIN1 is used when the SEL_DI input is 0 (Open). SP_REF_AIN2 is used when SEL_DI is 1
(Closed). The start commands (EXT) are also different for this application. When SEL_DI is 0, EXT0 should
be used and when SEL_DI is 1, EXT1 should be used.

2. LMT_SP_MIN
LMT_SP_MIN is used as a minimum speed. The drive will run at this speed anytime the start command is on
and the speed reference is less than LMT_SP_MIN.

Speed Control

The following figure shows the speed control block diagram.

The speed reference signal SP_R and the filtered speed feedback are input and the deviation between
these two is subjected to proportional/integral operations and output. After this signal is subjected to torque
filtering and torque limit processing, a torque reference SFC_T_R is output.

Control response is performed with the following parameter settings.

ASPR_A: Anti-overshoot gain

ASPR_AT: Anti-overshoot gain time constant

ASPR_P: Proportional gain

ASPR_W1: Response target

Note that if the GD

Circuit Operation (cont’d)

Simulator Follower Control (SFC, optional control used with a speed sensor)

When the machine has torsional resonance, the (SFC) function may be used to try to reduce the
torsional vibration and increase the speed response.

With SFC, the speed regulator output signal is input to an inertia compensation block. This block
produces an estimated speed signal. The speed feedback is then subtracted from this value to create a speed
deviation signal. This signal is then sent through a proportional block and added to the output of the spee d
regulator. The speed deviation signal is also sent through an anti-overshoot block and subtracted from the
speed regulator output. The combination of these two functions can be used to help improve the recovery of
the system during shock loading.

The speed deviation signal is also sent to a differential block and added to the torque reference (see
below). This signal is effective for torsional vibration control. When the SFC function is not used, set all of the
gains to 0.

Torque Reference and Current Reference

Signal SFC_T_R, the result of speed control, which is equivalent to the torque reference is input and
subjected to torque limit operation and di/dt processing. The differential output of the SFC control is then
added (if used). This is the torque reference that is sent to the current regulator.

D-Q Axis Current Control

The figure on the following page shows the block diagram of D-Q axis curre nt control.

This system controls the current of an induction motor by separating it into a magnetic flux (Field)
component and a torque component. This drive controls the current on the D-Q coordinates. It can control the
current to an AC motor as a DC value, achieving high performance control irrespective of output frequencies.

(1) ID (Field current) control

A magnetic flux reference is generated based upon the speed reference. This and the field current
setting (MI_ID_BASE) are used to generate an ID reference. This ID reference and the ID feedback signal are
input into a PI controller. The output of this controller is the ED_R (Field voltage reference). Optional
Inductance (L) compensation can also be used (ACR_WL). If used, this value is combined with the PI
controller output to create the ED_R.

(2) IQ (Torque current) control

The torque reference, which is the result of the previously mentioned speed control, is input and
divided by magnetic flux to obtain an IQ reference. This IQ reference and IQ feedback signal are input into a PI
controller. The output of this controller is the EQ_R (Torque voltage reference). An induction voltage
compensation (ACR_E2) and L compensation (ACR_WL) may also be used. If used these values are
combined with the output of the PI controller to create the EQ_R.

Circuit Operation (cont’d)
Output Voltage References

(1) Output voltage references

ED_R and EQ_R (the results of the current regulator) and the flux angle are input into a two to three

phase conversion block. This block outputs the phase voltage references to the PWM (pulse width

modulation) controller.

(2) PWM control

The PWM control section outputs gate pulse signals to the gate board based on the voltage reference

of each phase.

(3) Gate Signal Distribution board (GSD)

The GSD board receives the gate signals from the control board and sends them to the individual

power modules.

Circuit Operation (cont’d)
Speed Feedback (Option)

As an option, a Resolver or a Pulse Generator (PG) can be selected for speed feedback. Speed
control with a Tach Generator is not available because Tach Generator perform ance is poor.

Resolver

A resolver is an analog feedback device that used for speed feedback. Two sinewave excitati on
signals (sine and cosine) are sent to the resolver and two signals (sine and cosine) are returned to the drive.
The use of these two phase shifted signals allows the direction rotation to be determined. The position of the
motor rotor is determined by the phase difference between the excitation and return signals. The speed is
found from the change in this position over time.

PG

A signal is detected from a single ended PG attached to the motor and converted to a speed.
Detection is performed according to the pulse interval measurement system. This system converts a
signal to a speed based on the fact that the interval (time) between pulses input is inversely proportional to the
speed. The maximum input frequency is 10kHz.

OPERATION

The powering-on operation must follow a certain sequence. Failing to observe the powering-on

sequence described here may cause unnecessary stress on the equipm ent. Be sure to observe the

powering-on sequence.

WARNING

While the equipment is in operation and the motor is running, do
not turn off the main circuit power supply or control power supply under
any circumstances. Do not open the cubicle doors.

When the operation of the equipment is completely stopped, use the following basic procedure to turn
on/off the power.

NOTE: On some drives, the control power supply is internally derived from the main circuit power
supply. In this case, disregard the steps below involving the 480 Vac control power supply.

General power-on and power-off sequence.

Powering-on sequence

Powering-off sequence

Turn on control power supply.

480 VAC-50/60 Hz

Turn on main circuit power supply.

Check that operation is stopped.

Turn off main circuit power supply.

Turn off control power supply.

480VAC-50/60 Hz

- 42

Operation (cont’d)

Pre-Operation Check Points

Check the following points before starting the operation.

1) Wiring is correct.

2) A voltage of 2400 V, or 4160 V, ±10% can be supplied as the input power supply voltage.

3) A voltage of 480 VAC ±10% can be supplied as the control power supply voltage.

4) The ground bus and any shielded wire s are grounded.

5) The motor frame is also grounded.

6) The motor main circuit wire is not grounded.

Powering-On

The power should be turned on when the motor is completely stopped.

1) Turn on the control power supply MCCB "CONTROL."

2) Interlock the drive with the interlock switch on the keypad.

3) Turn on the main power supply.

4) Release the interlock switch on the keypad.

Operation

This section shows a typical operation procedure. You are also required to obse rve your own safety
rules to prevent accidents.

Normal Operation

When carrying out a normal operation using the digital interface (refer to the keypad manual for
keypad operation), check that the necessary interface signals are correctly connected and then follow the
procedure below.

1) Set the frequency command signal.

2) Turn on the IL (interlock) input signal if used.

3) Turn on the UVS input.

4) Turn on the EXT (start command) input signal.

5) Vary the frequency command as needed. Do not run the drive at zero speed unless you have a

speed sensor.

6) Turning off the EXT signal during operation ramps the motor to a stop.

7) Removing the UVS signal or the IL signal during operation turns off the output of the drive and the

motor coasts to a stop. If these signals are removed during operation, the EXT command must be

removed and the UVS and/IL restored before the drive will restart.

Powering-Off

1) Stop the motor by removing the EXT, the IL, or the UVS command.

2) After the motor has stopped, interlock the drive with the interlock button on the keypad.

3) Turn off the external main power supply.

4) Turn off the control power supply MCCB "CONTROL."

- 43

DATA CONTROL

Setting Data

The parameter setfile is stored in the EEPROM on the main control board. This is non-volatile
memory and will not generally be lost when the drive is powered down. However, this data could be lost if
there is a board failure. If this data is lost, the drive will need to be re-commissioned. For this reason, it is
recommended that the parameter setfile data be backed up in a file stored on a personal computer. This
requires the use of the optional commissioning software. The software and training is available through
Toshiba.

FAULT AND RECOVERY

Cautions when Handling Faults

When a fault occurs, before resetting, understand the fault code. It may be unsafe to restart if a
component or motor has failed. Every effort should be made to determine the cause of the fault and to correct
any problems before attempting to restart the drive.

To do this, it is necessary to record and evaluate the phenomena and conditions of the fault in detail
from both electrical and mechanical standpoints. Collect as much data as possible on the following items to
determine the operation situation when the fault occurred.

1) Record the fault message (fault display) shown on the display/keypad at the moment the fault

occurred.

2) Collection of trace back data. Record the trace back data by PC(option).

3) Operation different from ordinary operation

Check if there was anything that affected the input power supply of the equipment at the moment the

fault occurred (for example, powering-on of large-capacity equipment which is connected to the

common AC power supply or short-circuits, etc.).

4) Power failure

Check if the input power supply of the equipment was disconnected at the time of the fault (for

example, if the line of the AC power supply was switched or if the breaker was turned on or off).

5) Load condition

Check if the load was drastically changed at the time of the fault.

6) Operation

Check to see if any changes in the process or load machinery were made by the operator at the time

of the fault.

7) Installation environment

Check if there was any abnormal ambient conditions present in the electrical room at the time of the

fault or before the fault. (Fault of air-conditioner or ventilation system, water leakage into the room,

intrusion of dirt or chemicals, etc…)

CAUTION

- 44

8) Changes

Check if there were any recent changes to other equipment around the drive or load machinery. For

example, if some electrical work was carried out on or around the equipment.

9) Lightning

Check if there were any lightning strikes in the area.

10) Abnormal sound, odor

Check if there was any odor or abnormal sound around the equipment at the time of the fault or after.

Understanding the conditions before and during the fault can help to determine whether the fault is
attributable to factors inside or outside of the drive. Further, this information becomes an important clue to
determine the cause of intermittent faults. It is important to keep a precise record.

Repair

Cautions on Repair

• Be sure to use only the renewal parts specified by Toshiba. Parts other than those specified
by Toshiba may not only not demonstrate the stipulated performance but also affect the safety. If
spare parts are not available, contact Toshiba to order them or ask for replacement of parts.

• This equipment includes parts that need to be replaced periodically. It takes time to deliver
parts, so order them as early as possible.

1) The power modules have been designed for easy replacement as a unit. They are sold as units

and should be replaced as units. Individual parts should not be removed from or installed on the

power module assemblies. Modules that have failed or are believed to have failed should be returned

to the factory for evaluation, repair, and testing. Refer to the information label on the inside of the

power module compartment door for instructions on replacing a power module.

2) Prepare necessary tools and drawings, etc. before starting the work.

3) Be careful not to damage other parts when removing some parts.

4) Do not make wrong connections when changing parts. Put markings, etc., if necessary.

5) Before restarting after changing any part verify all connections are correct.

6) Use the right tools (torque wrench, etc.) when handling screws and bolts.

7) Special care is required when handling heavy articles.

8) When the work is completed, make sure that no tools or other foreign material is left in the drive.
