Cause : ID MAGN REQ comes when motor identification is required. This is a normal part of the drive's startup procedure, and it doesn't necessarily signify a problem.

The fault code FF30 in your ABB ACS800 drive indicates a requirement for motor identification. This isn't a critical fault but rather a prompt from the drive to define how it should identify the connected motor.

• Start Identification Magnetisation by pressing Start key, or select ID Run and start (see parameter 99.10).
