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.
Complete Troubleshooting Guide
- 1
Verify that all motor data, specifically the magnetizing inductance (Lm) and related parameters, are correctly entered in the drive.
- 2
Ensure the motor is compatible with the drive and that its electrical characteristics are fully defined in the drive's configuration.
