Cycle-by-cycle current limiting fault
AC drive
Meaning: The cycle-by-cycle current limiting fault applies only in asynchronous motor V/f control mode: this fault is reported if cycle-by-cycle current limiting continues for 500ms after the current exceeds the cycle-by-cycle current limit threshold.
Possible causes
- Check whether the load is too large or the motor has a locked rotor
- Output ground fault
- Motor interturn short circuit
- Incorrect motor nameplate parameters
- Output phase loss
- V/f oscillation
- Selected AC drive capacity is too small
