Overcurrent

Was bedeutet 1 ?

The AC drive has detected an excessively high current, exceeding 4 times the nominal current (4*IH), in the motor cables. This condition typically results from a sudden heavy increase in mechanical load, a short circuit within the motor cables, or the use of an unsuitable motor for the application. Subcode S1 indicates a hardware trip, while S3 points to current controller supervision.

• Motor load exceeding rated capacity.
• Mechanical binding or seizure in the driven equipment.
• Incorrect motor or drive sizing for the application.
• Short circuit in motor windings or power cables.
• Parameter P1-02 (Max current) set too low.

1. 1

   Check the mechanical loading on the motor shaft to ensure it is within expected limits.

2. 2

   Inspect the motor for any signs of damage or malfunction, and verify its suitability for the connected load.

3. 3

   Verify the integrity of the motor cables for any signs of insulation failure or short circuits between phases or to ground.
