Overcurrent shut-off during constant speed

What does Stedy Spd OC mean?

The inverter output is shut off because the output current reached or exceeded approximately 200% of the rated current while operating at a constant speed. This suggests a sudden increase in load or a fault in the motor/wiring during stable operation.

• Sudden, unexpected increase in mechanical load on the motor.
• Output short-circuit or ground fault occurring during constant speed operation.
• Motor experiencing mechanical binding or resistance during operation.

Click steps to track your progress.

1. 1

   Monitor the motor's mechanical load for sudden changes or spikes during constant speed operation.

2. 2

   Measure the motor load current during constant speed and compare it to the motor nameplate rated current.

3. 3

   Inspect motor cable and motor terminals for signs of short-circuit or ground fault.
