Section 1

INITIAL INSPECTION

Upon receipt of your VT130Q1, a careful Inspection for shipping damage should be
made. After uncrating, check:

1. Whether there are any parts which might be ioose, broken or separated.

2. Whether the rated capacity shown on the nameplate is the same as specified on
your order.

Periodically check the operating inverter for cleanlines?. Keep the cooling heatsink free
of debris. Check connections (with power off) for tightness. Proper maintenance and
operation will allow the inverter to give long troublefree service.

Storage

If the inverter is stored, it should be kept in a clean dry location free of temperature
extremes. Storage for longer than six months without power requires reconditioning of

the filter capacitor:

1. Apply bus voltage for a few seconds and check capacitor temperatures.

WARNING

Be sure charge light Is out before touching any component.

2. Repeat Step 1 several times monitoring capacitor temperatures, if a capacitor gets
warm, allow It to cool before repeating.

3. Capacitors are reconditioned when a constant bus voltage causes no heating.

PRINCIPLES OF OPERATION/APPLICATIONS

Most A.C. induction motors in the past have been limited to fixed speeds. The Toshiba
motor drive provides a simulated (RW.M.) A.C. that varies the speed of the motor.
Toshiba’s giant transistor (G-TR) is used with a microprocessor corttrolled regulator to
accomplish the conversion.

Motor speed ratings usually show the motor base speed at 60 HZ operation. Slower
speeds (below base speed) are produced by reducing both the voltage and the fre>
quency of the output.

H MOTOR

Figure 3-1 shows the voltage vary
ing with the frequency until base
speed (60 HZ) is reached. Above
base speed, the voltage remains
constant.

VOLTAQE

P.W.M. (Pulse Width Modulated) inverters change the incoming power to D.C. and then
pulse the D.C. into the motor leads to simulate A.C. Figu'e 3-2 shows a representation of
the Toshiba output voltage waveform.

An A.C. waveform is super

imposed on the pulse wave

for illustration.

Figure 3*3 is divided into three parts; the MAIN CIRCUIT which handles the input and
output power, the REGULATOR BOARD which senses input information to direct the
power transistors (GTR), and the optional REGENERATIVE POWER DISCHARGE UNIT
(D.B. unit).

V\/hen the input is first energized, contactors MS1 working with resistor R1, pro

vide a slow charge to filtering capacitors Cl. A red LED (light emitting diode)
on the base drive board turns on to indicate voltage on the bus.

A Hall-Effect D.C. current transformer (HCT) monitors bus current for the

regulator board.
Output to the motor is obtained by switching the D.C. bus with the transistor

(GTR) inverter. G-TR control comes from the regulator board through the base
amplifiers.

Pulse width is decreased for lower RMS voltage and increased for higher
voltage. Lower frequencies have a greater number of pulses in one cycle. As

the frequency increases, the microprocessor selects the optimum number of
pulses per waveform.

Switching of the transistors is controlled by the regulator board.

B. Regulator Board

Wiring diagrams at the end of this manual show a block diagram of regulator board
functions and adjustments.

The regulator board accepts operator information and outputs base signals to control
the Q-TR's. Refer to the wiring diagrams pages 14 and 15 for the following descriptions.

The operator speed pot. (frequency setting signal) is connected to CRF. REF. and OV.
0 to 12V DC at REF controls full range output of the inverter.

A 4 to 20mA signal can be connected at IRF and OV. A contact opening the CRF wire
of the speed pot. will automatically switch to this current reference. The cover mounted
speed pot. comes standard with this switch.

ST (start). F (forward), and R (reverse) connected to COM controls the start/stop func

tion and direction of inverter output.

Fault relay (contacts at FLA, FLB, and FLC) latches on if a fault occurs. Pressing the reset
button or remotely resetting will reset the relay. (Remote reset use term. RST to COM)

A low speed relay may be used to detect inverter speed below as HZ. (option)

Factory adjustment provides 0.5 to 80 HZ operation. Moving jumper J3 from the 60
HZ to the 50 HZ position automatically changes maximum output to 67 HZ. Fre

quency range is adjustable from 0.5 HZ to 80 HZ with 1F jumpered at J2. Jumping 2F

at J2 raises output frequency to 160 HZ and 4F at J2 raises output frequency to 320
HZ. Note that adjustments or changes in output frequency may require readjustment
of remote frequency meter and V/HZ.

The current detector monitors bus current from the HCT. If bus current rises to 163%,
stall prevention circuitry phases back both voltage and frequency until the current
decreases. 190% current shuts the Q-TR base drive off until current decreases. 240%
current turns base drive off and latches the fault relay and OC overcurrent display.

Bus voltage is monitored on the base drive board. Fast deceleration rates can cause

the bus voltage to rise when absorbing energy from the motor. If the bus voltage rises
to 750V (650V normal], deceleration time is lengthened regardless of setting. At Boov,

the inverter shuts down to protect filter capacitors C1 and Q-TRs from damage and
latches fault relay and OV display.

The microprocessor (CPU) develops base signals which are isolated and amplified by
the base driver circuit. Transformer T1 provides isolated low voltage A.C. which is rec
tified and filtered for the base driver amplifiers.

Section 3

Applications

VTISOGI provides a high quality output voltage and current, but it is not a perfect sine wave.
Therefore some increase in motor temperature, noise, and vibration may be noticed.

Special considerations must be taken when applying an inverter to an existing motor. At
slower speeds, cooling is not effective due to reduced fan RPM. FULL LOAD torque at slow
speeds may damage the motor due to overheating. In situations where the toad requires
high torque at slow speeds, the motor may require replacement with a large frame size
for heat dissipation.

Figure 3-7 shows a curve plotting acceptable torque vs. speed.

Note that for a safety margin, the torque
curve shows no more than 90%
motor rated torque at any speed.
If torque requirements at slow
speeds continuously exceed levels
shown in Figure 3-7, a larger motor
can be substituted.

Fixed speed machinery may not run properly at available speed ranges. Operation above
60 HZ may damage bearings or rotating parts. Slow speeds may provide insufficient lubrica
tion on oil filled gear boxes or speed reducers. Manufacturer specifications may need to

be consulted.

H MOTOR

FIGURE 3-7

The above precautions should be looked at carefully to prevent any problems. It is most
often the case, however, that the motor or motors on a variable speed application can be
directly applied to the VT130G1.

Section 4

INSTALLATION

(INVERTER MUST BE INSTALLED IN VERTICAL POSITION)

1. The ambient temperature must be between —10**C and AO^C (18 to 104 degrees

Farenheit). If the inverter is installed inside a self-contained panel or a large con

trol panel, there must be proper ventilation to keep the temperature between

-10*0 and40*C.

2. If the ambient temperature exceeds 40*0, it is necessary to remove the upper
and tower covers and the front cover. (When the inverter is installed inside an in
dependent panel or a control panel, remove the covers for adequate ventilation.)
This will improve ventilation and allow the ambient temperature rise up to 50*0,
(122*F), However, this reduces the strength of the side panel and therefore, the
operation panel should be left in place. (In lieu of the standard operation panel a

reinforcement bar can be used.)

Refer to page 70 for cover removal and reinforcement bar installation.

3. it is necessary for proper inverter operation to avoid high temperatures, humidity,
dust, or metal particles.

4. Corrosive gas and/or liquids must be avoided.

5. Install in an area where there is no vibration or noise from other electrical equip

ment and where maintenance can be performed easily.

WIRING

Refer to Figures 5-1 and 5*2, Standard Connection Diagram, Table 2, Standard Wire
Size, and Table 3, Inverter Rating Chart and use the following instructions. When wiring
the unit, the front cover of the inverter must be removed. The method of front cover
removal is shown on page 68.

1. Be careful not to apply commercial voltage to output terminals (U, V, or W). This
will damage the unit.

2. A surge suppressor must be connected across the excitation coil of the electro
magnetic contactor (MC) when used. Recommended surge suppressor: MARCON
Electronics DCR-10A25 (or RC type, .luf, 400V, 5000, V4W).

3. Grounding wire size at terminal E must be 3.5 mm2 or greater (#10 gauge).

4. Match the power supply voltage to the control power input terminals.

5. Use shielded, twisted wires for external connections of speed reference signals

(CRF, REF, IRF, OV) and also remote meter signals (FM. CM, OV).

6. Use a DC 1 mA meter for frequency and current meter. A 20 K ohms variable

resistor is needed for the ammeter scale calibration.

7. Connect either F (forward) or R (reverse) terminal to ST terminal through the
RUN/STOP switch. If there are two input signals from both F and R, F (forward)

command will override the reverse. The DRIVE-SW (RUN-STOP) on the operation
panel is connected to F (forward), therefore to perform reverse operation without
switching, two of the output terminal connections (U. V. and VV) must be inter
changed. if F (fonward) or R (reverse) is to be controlled externally, switch the

DRIVE-SW lead on the operation panel between F (tonward) and R (reverse).

8. When the standard integral operation panel is included and also a remote operators
station is to be used, the frequency reference signals from the integral operation
panel and the remote operation panel cannot be used at the same time. In such
case, disconnect the operation panel controls, or install a local/remote switch.

9. The 4 to 20 mA current input signal is not isolated in the inverter control circuit.
Toshiba recommends that signal common not be grounded since noise problems
may result.

10. CAUTION:

if auzillary contacts of the Main Contactor are not used, an external jumper must be
installed between EC1 and EC2, connect control power to the secondary of the input
contactor MC. Lost of input power will cause the FREQ/Fault display to go blank. Do
Not install a jumper between ST and COM on power units 7.5HP and above. This will
permanent!/ damage soft charge circuitry if EC1 and EC2 have not been wired in
accordance with the Instruction Manual.

REQ UI REM ENTS/START-U P/ADJ USTM ENTS

Requirements

Unless supplied in a special optional enclosure, the ESPlSOGt should be installed in г
area where:

1. Cabinet mounting is upright, leaving room for door clearance.

2. Ambient atmosphere is free of dust, corrosive gases, high moisture content and
temperature extremes.

3. Vibration is kept to a minimum.

4. Unit should be easily accessible tor maintenance and troubleshooting.

Procedures

Each ESP130G1 is shipped with wiring diagrams that show necessary interconnections,

standard unit with operator controls in the door, simply requires connecting input power

and output to the motor. A remote operator station and other options require more
interconnections.

Terminal numbers in the standard units are shown clearly in wiring diagrams. Terminal

strips are mounted at a convenient angle for easy access.
Read the following precautions before installing the inverter:

1. Signal wires, (speed pots, meters. 4 to 20 mA) should be twisted conductors and ruf
in separate conduit.

2. The inverter enclosure should be grounded to conform with electrical codes.

3. Noise suppressors should be attached to the coils of all relays and contactors that
are added to the enclosure. RC type, Electro Cube #RG 1983*8-12 or varistor type
#GE-V250PA40C (230V coil), #GE-V150PA20A (115V coil).

Prepower Checks

Before energizing power, check the following:

1. For any wiring errors or grounds.

2. Source voltage to ensure rated input voltage.

16

Section 5

Initial Operation

1. Initial conditions before power up:
a) Frequency pot. (speed adjustment) should be at minimum setting.

b) Fdrward/Reverse switch (if used) in forward position.

2. Energizing the input terminals will charge the DC bus in the power unit and the
charge LED will come on.

3. Run the inverter without connecting motor. Make sure frequency is going up. Stop
inverter and turn off the breaker.

4. Connect the motor.

5. Adjusting the speed pot. slightly CW should start the motor turning, if motor runs
backwards: stop inverter, turn off power, and reverse any two output leads U, V, W to
correct direction.

6. Forward/Reverse (If used) should be checked while motor is running. Engage switch
to reverse, motor should stop, and reverse direction to the same speed it was
running in forward.

7. increase speed to full speed slowly, watch motor operation. Leave setting at full
speed. Switch to STOP Motor should decelerate or coast without tripping off inverter.
Switch to RUN, motor should accelerate smoothly to full speed without tripping
inverter.

Variable Resistors (On Power Unit Control Board)

The variable resistors are adjusted to specification at the factory and should not be
touched unless necessary.

(Caution when adjusting)

1. Small-scale precision type variable resistors are used. Use a well insulated thin type
minus screwdriver.

2. When the power is on, a high voltage is applied to the parts on the printed circuit
board. Also, after the power is turned off. the large capacitor is charged for about
five (5) minutes.

WARNING

Do not touch any circuit while the CHARGE lamp Is on.

3. A digital counter and an oscilloscope are necessary for readjustment. Do not ground
the instruments when connecting and keep the input impedance of the instruments
over 10 K ohms.

4. When monitoring the waveform with an oscilloscope, turn off the power before
connecting or disconnecting the probe.

down occurs during normal machine operation, adjustment is necessary. Table 32, page
shows a list of adjustments and ranges.

WARNING!

Adjusting the Inverter with power on requires special precautions:
Ail test equipment should be connected and disconnected with

POWER OFF.
High voltage exists on the base driver board, all potentiometers

should be adjusted with insulated handie screwdrivers.
Grounded test equipment, such as oscilloscopes, may damage the

SPEED REFERENCE ~ is measured at the wiper of the speed pot. at the power unit.
REF to OV. 12 VDC means maximum output of the inverter.

4 to 20 mA REFERENCE is measured at terminal IRF to OV. Potentiometer 5RH adjusts
for zero speed at 4 mA.

Voltage. Frequency REF is measured at test point REF to common. Factory set at the
voltages shown in Table 4, potentiometer 9RH can be used to adjust desired maximum
output frequency. The V/Hz ratio stays the same for proper motor operation. Potentiometer

10RH adjusts the minimum speed.

V is used to determine the V/Hz ratio. Measured at V test point to common, SV means
maximum output voltage has been reached.

HERTZ - is measured at OF test point. Hertz is a strobe pulse with a frequency 1152
times inverter output frequency. 69, 120Hz means the inverter is running 60 Hz. (This

testpoint is an open collector and requires a pullup 20K ohms resistor for readouts.)

VOLTAGE BOOST - is a V/Hz adjustment at 3 RH. Output voltage at low frequencies is
raised for more starting torque.

_

A procedure is described below for recalibrating the power unit assuming all poten
tiometers are misadjusted. When using an oscilloscope or frequency counter, the motor
does not have to be connected.

1. Initial Conditions 3RH - full counter clockwise (C.C.W.), 9RH - full C.W., 10RH - full
C.C.W.

2. Set Maximum Frequency. Run inverter. Adjust poL 2RH for desired maximum speed

with manual speed pot. fully clockwise. Digital frequency meter will show true output
hertz.

3. Calibrate Remote Meter. Use 1RH pot. to set scale on optional remote meter.

4. Adjust Volts Per Hertz. Turn manual speed pot. to 60 Hz. Adjust 4RH pot. for

5 VDC @ test point “V" to Com.

5. 4 to 20 mA Input. Enable auto mode. Minimum speed at 4 mA can be adjusted with

pot. 5RH. Maximum speed at 20 mA can be adjusted with pot. 6RH. Pots. 5RH and
6RH interact.

Section

FIGURE 3-1

6. Upper and Lower Limits Pot. lORH adjusts lower limit and will override minimum
speed set in step 5. Pot. 9RH adjusts upper limit and will override maximum speeds
set in 2 and 5.

7. Voitag« Boost Pot. 3RH increases low speed breakaway torque. Note: High voltages
at low frequency may burn up the motor.

8. Overvoltage Level factory set for safe operation. It should never be adjusted.

9. Check Motor Current at several different operating speeds after completion of
adjustments. Continuous currents above the motor nameplate (rated) current may
damage the motor.

e) Switching between two or more variable resistors:

Two or more pots are set at
different frequencies and selected.

Use small current rated relay for
selection.. Disconnect the door
mounted pot from terminals CRF,
REF. and OV

f) Multiple inverter cascading with one setting device:

Connect 3 K ohm w resistor
between CRF and OV terminal of
each slave unit. Disconnect the
door mounted pots on all units.

No 1 uak

g) Multiple inverter cascading from one process signal:

4 to 20 mA input signal cannot be used. Use voltage (0 to 12v) signal only in
to all inverters. Turn door mounted speed pots into OFF position.

h) Selection of a variable resistor other than 3 kn for speed setting.

(3 kn variable resistor is furnished
on inverter door)

A 750n fixed resistor is to be used as R1 in the inverter unit so that the REF
value (Vf^Ep) is between 0 and 12V when regulator R2 is 3 kn and the voltage
(Vnep) is divided by R1 and R2.

If the resistance value of the regulator is to be changed, a compensation resistor

R3 is required.

If a fixed resistor cannot be selected because R3 is not a round number, change R2

or use a variable resistor for R3.

Selection examples:

<f - 1> When using a 5 k ohms

Note: If the regulator is less than 3 k ohms, REF voltage becomes less than 0 to 12 V

and the maximum inverter output frequency decreases. Therefore R3 must be
greater than 3 k ohms. However, if V/F characteristic between 9 and 12 V (shaded
area) is not required, a regulator between 1.2 and 3 k ohms can be used.

Bsfore performing inspection, be sure to open the input circuit breeker (MCCB). Wiit
for it least 5 minutes, and check that the “CHARGE" lemp Is “OFF’’ and then start
inspection. The “CHARGE" lamp being "ON" Indicates that the inverter unit is still

energized by the main capacitor.

1. Check for loose wiring at terminals and damaged wires.

2. Check that the vents are not clogged by dust or debris.

3. Check that there is no dust on the printed wiring board and inside the unit.

4. if the inverter unit has been unuaed for a long period, turn on the power at least
once every six months to check its operation. The protection against dust, cor
rosive gas. high temperature, and excessive humidity must be continued during
any unused period. Periodic inspection is required.

5. Oo not allow excessive vibration of the unit since damage mey occur.

6. If necessary, perform megger test only for main circuit tsrmlnsis with a OC 500 V
megger,

Note: Perform megger test with the terminals shorted. Do not test the

terminals on the printed circuit board with a megger.

7. Measuring instruments

Measuring instruments may not ahow the correct measurements because of the

TROUBLESHOOTING PROCEDURES

Improper adjustment, wiring, or inverter malfunction can cause the fault relay to latch.

To reset a fault, the reset button must be pressed or reset by remote signal.
Figure 12-1 is a trouble shooting flow chart in the event the motor does not run. Table 10

shows some trouble indications and causes.

WARNING

When troubleshooting with power on, care must be taken to avoid elec
tric shock. Grounded test equipment may damage Inverter. D.C. BUS
voltage remains charged for several minutes after power is removed.

NOTE: Other Jumper connections are for factory use. Removing or changing may

cause improper operation.

NOTE 1: If extended frequency ranges are required: A jumper at 2F will raise

the maximum to 120 HZ (or double the original frequency). The testpoint
OF now gives a frequency pulse 576 times output frequency. A jumper at
4F will raise the maximum to 240HZ (or 4 times the original frequency).
The testpoint OF now gives a frequency pulse 286 times output
frequency.

Transformer T1 Troubleshooting

Fuse FU1 blowing can indicate a wiring problem, a bad transformer, or a bad regulator
board. Page 6 of the wiring diagram (main circuit) shows transformer connections and
output voltages.

Section 13

PARTS REPLACEMENT AND PRECAUTIONS

1. Before replacing parts, check that power is not supplied to the inverter and the
main circuit capacitor is not charged (CHARGE lamp is not illuminated).

2. Replacement of parts on the printed circuit board must be performed by trained
personnel. Please contact your dealer.

3. Removing the printed circuit board

The printed circuit board is fastened with locking supports at four corners.

Remove the connectors on the circuit board, remove the locking support and then
remove the circuit board.

4. Removing connectors on the printed circuit board

Connectors are held with stoppers. Release the stopper and pull the connector
out carefully. Do not pull on the wire.

To plug the connector back in, push it in place to lock with the stopper.

Excessive force may cause damage. Hold the circuit board and push gently. Also
check the connector numbers and match the pins correctly.

In some models the connector on the base drive circuit board is difficult to get at.
In such case, remove the locking support and lift the circuit board so that the
connector can be grasped easily before removing.

5. Replacing LED (7 segment indicator)

The LED indicator is plugged in a socket and can be easily replaced, but it
should not be removed unless necessary.

Section 13

If it must be replaced, refer to the following figure. The location and direction
must be checked carefully.

Op«n

LEDI

6. Replacing main circuit. G-TR (Transistor)

The connecting wires are not numbered. Therefore, when replacing, numbering
the wires is suggested to prevent mis-connection.

Apply a silicone compound on the contact surface of G-TR cooling fins.

Typical types of silicone compound are as follows. Alcan by Alcan,Jointal S-200

by Nikkei Kako. The method of GTR checkout is shown on page 61.
