Troubleshooting Causes and corrective actions
FR-E700 EC 7 - 9
Operation Panel

FR-PU07
OC During Dec
Name Over current shut-off during constant speed
Description
When the inverter output current reaches or exceeds approximately 230% of the rated cur-
rent during constant speed operation, the protective circuit is activated and the inverter
trips.
Check point
1) Check for sudden load change.
2) Check for output short circuit/ground fault.
3) Check that stall prevention operation is correct.
Corrective action
1) Keep load stable.
2) Check the wiring to make sure that output short circuit/ground fault does not occur.
3) Perform a correct stall prevention operation. (Refer to section 6.3.5).

OC During Dec
Name Over current shut-off during deceleration or stop
Description
When the inverter output current reaches or exceeds approximately 230% of the rated
inverter current during deceleration (other than acceleration or constant speed), the protec-
tive circuit is activated and the inverter trips.
Check point
1) Check for sudden speed reduction.
2) Check for output short circuit/ground fault.
3) Check for too fast operation of the motor’s mechanical brake.
4) Check that stall prevention operation setting is correct.
Corrective action
1) Increase the deceleration time.
2) Check the wiring to make sure that output short circuit/ground fault does not occur.
3) Check the mechanical brake operation.
4) Check that stall prevention operation setting is correct. (Refer to section 6.3.5.)

Name Regenerative over voltage shutoff during acceleration
Description
If regenerative energy causes the inverter's internal main circuit DC voltage to reach or
exceed the specified value, the protective circuit is activated and the inverter trips. The cir-
cuit may also be activated by a surge voltage produced in the power supply system.
Check point
1) Check for too slow acceleration (e.g. during downward acceleration in vertical lift load).
2) Check that the Pr. 22 "Stall prevention operation level" is not too low.
Corrective action
1) Decrease the acceleration time.
Check that regeneration avoidance function (Pr. 882, Pr. 883, Pr. 885, Pr. 886) is used.
(Refer to section 6.20.4)
2) Set a correct value in Pr. 22 "Stall prevention operation level".

Name Regenerative over voltage shut-off during constant speed
Description
If regenerative energy causes the inverter's internal main circuit DC voltage to reach or
exceed the specified value, the protective circuit is activated to stop the inverter output. The
circuit may also be activated by a surge voltage produced in the power supply system.
Check point
1) Check for sudden load change.
2) Check that the Pr. 22 "Stall prevention operation level" is not too low.
Corrective action
1)
Keep load stable.
Check that regeneration avoidance function (Pr. 882, Pr. 883, Pr. 885, Pr. 886) is used.
(Refer to section 6.20.4)
Use the brake resistor, brake unit or power regeneration common converter (FR-CV)
as required.
2) Set a correct value in Pr. 22 "Stall prevention operation level".
