How can resolve problem F0041 fault in siemens micromaster 440 or MM440 drive ?
Cause : Motor Data Identification Failure. Motor data identification failed.
Alarm value = 0: Load missing
Alarm value = 1: Current limit level reached during identification.
Alarm value = 2: Identified stator resistance less than 0.1% or greater than 100%.
Alarm value = 3: Identified rotor resistance less than 0.1% or greater than 100%.
Alarm value = 4: Identified stator reactance less than 50% and greater than 500%
Alarm value = 5: Identified main reactance less than 50% and greater than 500%
Alarm value = 6: Identified rotor time constant less than 10ms or greater than 5s
Alarm value = 7: Identified total leakage reactance less than 5% and greater than 50%
Alarm value = 8: Identified stator leakage reactance less than 25% and greater than 250%
Alarm value = 9: Identified rotor leakage inductance less than 25% and greater than 250%
Alarm value = 20: Identified IGBT on-voltage less than 0.5 or greater than 10V
Alarm value = 30: Current controller at voltage limit
Alarm value = 40: Inconsistence of identified data set, at least one identification failed
Percentage values based on the impedance Zb = Vmot,nom / sqrt(3) / Imot,nom
Diagnosis & Remedy
Check the following:
- 0: Check that the motor is connected to the inverter.
- 1-40: Check if motor data in P0304 P0311 are correct.
- Check what type of motor wiring is required (star, delta).
