Cause : Illegal current dissymmetry comes when the deviation of the individual currents of the power units exceeds the alarm threshold specified in p7010.

Alarm value (r2124, interpret decimal):
1: Phase U.
2: Phase V.
3: Phase W

- inhibit the pulses of the faulted power unit (p7001).
- check the connecting cables. Loose contacts can cause current spikes.
- the motor reactors are non-symmetrical or faulty and must be replaced.
- the CTs must be calibrated or replaced.
