6 Troubleshooting
Percentage values based on the impedance Zb = Vmot,nom / sqrt(3) / Imot,nom
Diagnose & Remedy
Fault value = 0: Check that the motor is connected to the inverter
Fault value = 1-40:
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
F0051 Parameter EEPROM Fault
Possible Causes
Read or write failure while saving non-volatile parameter
Diagnose & Remedy
Factory Reset and new parameterization
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
Check data
Change IO board
F0054 Wrong IO Board
Possible Causes
Wrong IO board is connected
No ID detected on IO board, no data
Diagnose & Remedy
Check data
Change IO board
F0060 Asic Timeout
Possible Causes
Internal communications failure
Diagnose & Remedy
If fault persists, change inverter
Contact Service Department
F0070 CB setpoint fault
Possible Causes

5: Identified main reactance less than 50 % and greater than 500 %
6: Identified rotor time constant less than 10 ms or greater than 5 s
7: Identified total leakage reactance less than 5 % and greater than 50 %
8: Identified stator leakage reactance less than 25 % and greater than 250 %
9: Identified rotor leakage inductance less than 25 % and greater than 250 %
20: Identified IGBT on-voltage less than 0.5 V or greater than 10 V
30: Current controller at voltage limit
40: Inconsistency of identified data set, at least one identification failed
Check if motor data in P0304 to P0311 are correct
= 1: Inconsistent readings
