Fagor alarm 4152: ERROR 507: Motor not found in .MOT file
CNC 8055 SERCOS drive error (DDS) · Fagor DDS drives
What it means
The motor selected in the drive parameters does not exist in the loaded .MOT motor database. PWM is deactivated (category 0 stop) and a power cycle after loading the right database is required to recover. Verify motor code against the ordering handbook/database version.
Likely causes
- Wrong motor code parameterized (typo or different motor fitted)
- .MOT database too old/new for the motor used
- Drive swapped without matching database
