OP3 000C Overvoltage
(during
constant
speed
running) 1) Input voltage is high and showed
abnormal fluctuation.
2) Connection is made as the following
system.
• Power supply capacity is 500 kVA or
more.
• The power factor improvement
capacitor was opened/closed.
• Equipment is connected that uses
thyristor on the same system.
3) The motor was rotated with the force on
the load side, and it became to
regenerative status.
1) Use within the power supply voltage
range. When no problem is found in the
input voltage, install an input AC
reactor (option).
2) Install an input AC reactor (option).
3) Install a braking resistor (option).
Ot 0020 Overtorque * The load torque reached the overtorque
level during run. • Check the load side.
• Check the overtorque detection setting is
correct.
<F615: Overtorque trip>,
<F616: Overtorque detection level during
power running>,
<F617: Overtorque detection level during
regen>,
<F618: Overtorque detection time>, etc.
Ot2 0041 Overtorque 2 1) The output current during power
running reached <F601: Stall
prevention level 1> or more, and the
setting time in <F452: Stall detection
time during power running> elapsed.
2) The power running torque during power
running reached <F441: Power running
torque limit level 1> or more, and the
setting time in <F452: Stall detection
time during power running> elapsed.
• Reduce the load.
• Lower the detection level of <F601> or
<F441>.
OtC3 0048 Overtorque/
Overcurrent * Overtorque or overcurrent on the shock
monitoring function was detected. • Check the load.
• When no problem is found, check if the
shock monitoring function setting is
correct.
<F590: Shock monitoring> to <F598:
Shock monitoring detection condition>
PrF 003B STO circuit
fault Fault in the safe torque off (STO) circuit. Fault inside the inverter.
Contact your Toshiba distributor.
SOUT 002F PM step-out * 1) The load changed rapidly.
2) Sudden acceleration/deceleration
occurs.
3) The motor shaft is locked up.
4) Output side phase has failed.
1) and 2) Increase the acceleration/
deceleration time. <ACC: Acceleration
time1>, <dEC: Deceleration time 1>,
etc.
3) Check the motor and release the lock.
4) Check the wiring on the output side.
UC 001D Undercurrent
* The output current declined to the
undercurrent detection level during run. • Check the load.
• Check that the undercurrent detection
setting is correct.
<F610: Undercurrent trip>,
<F611: Undercurrent detection level>,
<F612: Undercurrent detection time>, etc.
*Enable/Disable can be selected for trip with a parameter.
