Overcurrent

What does 1 mean?

A hardware trip (S1) has detected excessively high current (>4 times nominal current) in the motor cable, potentially due to a sudden heavy load, a short circuit in the motor cables, or an incorrectly matched motor. Other subcodes (S3, S4) indicate current controller supervision issues or an exceeded user-configured limit.

• Motor or load current exceeds the nominal rating (e.g., P1-10 = 15A).
• Short circuit in the motor windings or power cables.
• Mechanical overload on the driven equipment.

Click steps to track your progress.

1. 1

   Inspect the motor's mechanical loading and reduce if exceeding the motor's nominal capacity.

2. 2

   Verify the motor's specifications (e.g., nominal current, voltage, power) match the AC drive's rating and application requirements.

3. 3

   Visually inspect the motor cables for damage, proper routing, and verify all connections are secure and free of short circuits.

4. 4

   Perform an identification run to ensure the drive's motor parameters are accurately tuned to the connected motor.
