F00041 Motor Data Identification Failure
Reaction: OFF 2
Acknowledge: Quit fault eg. via DI2
Cause: Motor data identification failed.
• r0949 = 0: Load missing
• r0949 = 1: Current limit level reached during identification.
• r0949 = 2: Identified stator resistance less than 0.1% or greater than 100%.
• r0949 = 3: Identified rotor resistance less than 0.1% or greater than 100%.
• r0949 = 4: Identified stator reactance less than 50% and greater than 500%
• r0949 = 5: Identified main reactance less than 50% and greater than 500%
• r0949 = 6: Identified rotor time constant less than 10ms or greater than 5s
• r0949 = 7: Identified total leakage reactance less than 5% and greater than 50%
• r0949 = 20: Identified IGBT on-voltage less than 0.5 V or greater than 10 V
• r0949 = 30: Current controller at voltage limit
• r0949 = 40: Inconsistence of identified dataset, at least one identification failed
• r0949 = 41: Writing of calculated magnetizing current P0320 failed
• r0949 = 42: Writing of identified stator resistance failed
• r0949 = 43: Writing of identified rotor resistance P0354 failed
• r0949 = 44: Writing of identified rotor time constant P0622 failed
• r0949 = 45: Writing of identified mutual reactance P0360 failed
• r0949 = 46: Writing of identified stator leakage reactance P0356 failed
• r0949 = 47: Writing of identified rotor leakage reactance P0358 failed
• r0949 = 48: Writing of identified on voltage P1825 failed.
• r0949 = 49: Writing of the identified dead time compensation P1828 failed
Percentage values based on the impedance Zb = Vmot,nom / sqrt(3) / Imot,nom
Remedy: Check the following:
• r0949 = 0: is the motor connected to the inverter.
• r0949 = 1-49: are the motor data in p0304 - p0311 correct.
• Check what type of motor wiring is required (star, delta).
F00042 Speed Control Optimisation Failure
Reaction: OFF 2
Acknowledge: Quit fault eg. via DI2
Cause: Motor data identification failed.
• r0949 = 0: Time out waiting for stable speed
• r0949 = 1: Inconsistent readings
Remedy: Make sure motor has data been entered correctly.
Motor data identification needs to have been done.
