Current Calibration Fault

What does 3 mean?

This fault indicates a problem with the current calibration on one of the motor phases (T1/U, T2/V, or T3/W). This typically points to an issue with the motor connections or the motor itself, or an internal drive problem related to current measurement accuracy. Improper calibration can lead to inaccurate motor control.
