Powerstack fault
Fault caused by the following events:
(1) dc-link overcurrent = short circuit of
IGBT
(2) short circuit of chopper
(3) earth fault
Framesizes A to C (1),(2),(3)
Framesizes D to E (1),(2)
Framesize F (2)
Since all these faults are assigned to one
signal on the power stack, it is not
possible to establish which one actually
occurred.

F0030
Fan has failed
Fan no longer working Fault cannot be masked while options module (AOP
or BOP) is connected.Need a new fan.

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 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
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).
