Description Possible causes Remedies
GV[R
Inverter type
error
•Is circuit board (or main
circuit/drive circuit board)
replaced?
•When board has been replaced, input  for
V[R.
G
Analog input
terminal
overvoltage
•Overrated voltage is applied to
analog input.
•Apply voltage within the rated voltage.
GSequence error
•The signal from system is not
inputted into input terminals.
•The input terminal function (,
) is not set up.
•Please check if the sequence is normal or not.
•Please set  or  as the input terminal to
use.
GEncoder error
•Disconnection of encoder circuit.
•The encoder is not connected
correctly.
•Check connection of encoder.
Connect encoder correctly.
•Check whether the setting of H matches the
phase-A and phase-B connections of the encoder.
G
Speed error
(Over speed)
•Speed error (Inverter error,
Encoder error)
•Over speed by overvoltage limit
operation
•Using braking function in not
connect a motor
•Check the setting of H ~ H
•Check connection of encoder.
•In the case of overvoltage limit operation, install a
dynamic braking resistor.
•Operation in connect a motor
G
Terminal input
error
•Braking down of a wire for VI/II
input signal.
•Terminal circuit board comes off
and falls
•P24 overcurrent
•Check VI/II input signal.
•Install the control terminal board to the inverter.
•Check P24 terminal short circuit to CC or CCA.
G
Abnormal
CPU2
communication
•An error arises during CPU2
communication.
•Contact your Toshiba distributor.
GV/f control error
• Output voltage / Output frequency
ratio is too high compared to motor
rating.
• It was run in vector control mode
(RV=,,, or ) without
setting parameters (Auto-tuning)
concerning the motor.
• Motor was in over-excitation state
during deceleration.
• Motor constant 1 (Torque boost)
f410 is too large.
• Motor was started under the brake
closed.
• Set Base frequency voltage 1 vlv and Base
frequency vl in accordance with motor rating.
• When operating a motor in V/f control mode
selection RV=,,, or , follow section
6.19, and then set the parameters (Auto-tuning)
concerning the motor.
• If the inverter is tripped during deceleration
because of V/f control error (e-20) when
f305 (Over voltage limit operation) is set to 2 or
3, decrease the value for f319 (Regenerative
over-excitation upper limit)..
• If the inverter is tripped during low frequency,
decrease the value for f410.
• If the inverter is tripped during braking, make the
brake release timing early.
GCPU1 fault
•A software error occurs in the
control CPU.
•Contact your Toshiba distributor.
G
Abnormal logic
input voltage
•An abnormal voltage is applied to
the control logic input terminal.
•Check the signal given to the logic connected with
the input terminal.
GOption 1 error
•Option card 1 is defective.
(Installed option at lower side)
•Contact your Toshiba distributor.
GOption 2 error
•Option card 2 is defective.
(Installed option at upper side)
•Contact your Toshiba distributor.
G
Stop position
retaining error
•A deviation error occurs during
stop position retaining control.
•Creeping speed is too fast.
•Check connection of encoder.
•Adjust the proportional P gain H.
•Lower the creeping speed.
G
Internal circuit
error
•Motor control CPU is defective.
•The drive circuit board in the
inverter was damaged.
•Power device is defective.
•Using braking function in not
RV=,,,, or  mode
•Contact your Toshiba distributor.
•If the braking function is used, operate a motor in
RV=,,,, or  mode
G
Control power
backup
undervoltage
error
•The control voltage between +SU
and CC terminals is too low.
•Control power is not supplied
through +SU and CC terminals.
•The parameter H is not set
correctly.
•Check whether the voltage between +SU and CC
terminals is DC20V or more.
•Set H to 0 if a control power backup device
is not connected to +SU and CC terminals.
To reset the inverter that has been tripped
because of this error, turn it off and then back on.
UQWV
Step-out (for
PM motors
only)
•The motor shaft is locked.
•One output phase is open.
•An impact load is applied.
•Unlock the motor shaft.
•Check the interconnect cables between the
inverter and the motor.
