OC During Dec
Overcurrent shut-off during deceleration
Mitsubishi Electric · FR-E500 Inverter
¿Qué significa OC During Dec ?
The inverter output is shut off because the output current reached or exceeded approximately 200% of the rated current during the deceleration phase. This can be caused by too rapid deceleration, issues with mechanical braking, or a fault in the motor/wiring.
Causas comunes
- Motor decelerating too rapidly for the load or inverter's braking capability.
- Output short-circuit or ground fault occurring during deceleration.
- Mechanical brake on the motor engaging too quickly or aggressively.

- 1
Increase the deceleration time setting (e.g., Pr. 8 or Pr. 45) to allow for a smoother slowdown.
- 2
Adjust the operation of the motor's mechanical brake to ensure it is not engaging too quickly or causing excessive current spikes.
- 3
Inspect motor cable and motor terminals for signs of short-circuit or ground fault.
