F0041 Failure, motor data identification fault in siemens micromaster 420 or MM420 drive

Cause

Motor data identification run unsuccessful (refer to fault value r0949):
- r0949 = 0: Load missing.
- r0949 = 1: Current limit value reached during identification.
- r0949 = 2: Identified stator resistance less than 0.1% or greater than 100%.
- r0949 = 30: Current controller at voltage limit value
- r0949 = 40: Identified data set inconsistent; at least one identification run unsuccessful

Diagnosis & Remedy

Please check the following:
- r0949 = 0: Is the motor connected to the inverter ?
- r0949 = 1-40: Is the motor data in P0304-P0311 correct ?
- r0949 = 1-40: Motor circuit configuration correct (star, delta configuration)

1. Check motor data
2. Check loading on motor
3. Boost settings too high (P1310,P1311, P1312)
4. Check parameter for motor thermal time constant
5. Check parameter for motor I2t warning level
