Fault Tracing
Possible cause
Current measurement has
detected that there is no current
in one motor phase
IGBT switch temperature is under
-10 C
0
IGBT switch temperature is over
120 C. Overtemperature warning
is issued when the IGBT switch
temperature exceeds 110
Motor stall protection has tripped
Motor overheating has been
detected by inverter motor tem-
perature model. Motor is over-
loaded
Motor underload protection has
detected a low load situation
Parameter save fault
• Faulty operation
• Component failure
• Faulty operation
• Component failure
Ambient interference or defective
hardware
Application does not function
Current at the analogue input is
in
< 4mA
• Control cable is broken or
loose
• Signal source has failed
Correcting actions
Check motor cable and
motor.
Check the ambient tempera-
ture.
Check that the cooling air
flow is not blocked.
Check the ambient tempera-
ture.
Make sure that the switching
C frequency is not too high in
0
relation to ambient tempera-
ture and motor load.
Check motor.
Decrease the motor load.
If no motor overload exists,
check the temperature
model parameters.
FAN: check that belt is not
broken.
PUMP: check that pump is
not dry.
Contact technical support.
Reset the fault and restart.
Should the fault recur, con-
tact technical support.
Should the fault recur, con-
tact technical support.
Contact technical support.
Check the current loop
circuitry.
