Possible Causes
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
rotorresistance 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
Read or write failure while saving
non-volatile parameter.
Read failure for power stack
information or invalid data.
Read failure for IO EEPROM
information or invalid data.
Ø Wrong IO board is connected.
Ø No ID detected on IO board, No
data.
Internal communications failure
No setpoint values from CB
(communication board) during
telegram off time
Diagnose & Remedy
0: Check that the motor is connected to the
inverter.
1-40: Check if motor data in P304-311 are correct.
Check what type of motor wiring is required (star,
delta).
1. Factory Reset and new parameterization
2. Change drive
Change drive
1. Check data
2. Change IO module
1. Check data
2. Change IO module
1. If fault persists, change inverter,
2. Contact Service Department
Check CB and communication partner
