4074

Can't set magnetizing inductance

ABB · ACS850 Standard Program Firmware

What does 4074 mean?

The drive is unable to set the motor's magnetizing inductance (Lm) parameter. This usually points to incorrect or incomplete motor data, which is crucial for the drive's internal motor model and control algorithms. Incorrect Lm can lead to suboptimal motor performance or control instability.
