MICROMASTER 411 & COMBIMASTER 411 Operating Instructions
84
6SE6400-5CA00-0BP0
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
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 if motor data in P0304 to P0311 are correct
Check what type of motor wiring is required (star, delta).
F0042 Speed Control Optimisation Failure OFF2
Possible Causes
Speed control optimisation (P1960) failed
Fault value = 0: Time out waiting for stable speed
= 1: Inconsistent readings
F0051 Parameter EEPROM Fault OFF2
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 OFF2
Possible Causes
Read failure for power stack information or invalid data
Diagnose & Remedy
Hardware defect, contact Customer Support / Service Department
F0053 IO EEPROM Fault OFF2
Possible Causes
Read failure for IO EEPROM information or invalid data
Diagnose & Remedy
Check data
Change IO board
F0054 Wrong IO Board OFF2
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 OFF2
Possible Causes
Internal communications failure
Diagnose & Remedy
If fault persists, change inverter
Contact Service Department
F0070 CB setpoint fault OFF2
