F0041 Motor Data Identification Failure
Possible Causes
Motor data identification failed.
Fault value = 0: Load missing
Percentage values based on the impedance Zb = Vmot,nom / sqrt(3) / Imot,nom
Diagnose & Remedy
! Fault value = 0:
! Fault value = 1-40: Check if motor data in P0304 to P0311 are correct
Check what type of motor wiring is required (star, delta).
F0042 Speed Control Optimisation Failure
Possible Causes
Speed control optimisation (P1960) failed
Fault value = 0: Time out waiting for stable speed
= 1: Inconsistent readings
F0051 Parameter EEPROM Fault
Possible Causes
Read or write failure while saving non-volatile parameter
Diagnose & Remedy
1. Factory Reset and new parameterization
2. Contact Customer Support / Service Department
F0052 Power stack Fault
Possible Causes
Read failure for power stack information or invalid data
Diagnose & Remedy
Hardware defect, contact Customer Support / Service Department
F0053 IO EEPROM Fault
Possible Causes
Read failure for IO EEPROM information or invalid data
Diagnose & Remedy
1. Check data
2. Change IO board
