Possible cause
There is too high a current
(>4*I H) in the motor cable.
Its cause can be 1 of these.
a sudden heavy load
•
increase
a short circuit in the
•
motor cables
the motor is not the
•
correct type
the parameter settings
•
are not properly made
The DC-link voltage is
higher than the limits.
the deceleration time is
•
too short
high overvoltage spikes
•
in the supply
The measurement of cur-
rent tells that the sum of the
motor phase current is not
0.
an insulation malfunc-
•
tion in the cables or the
motor
a filter (du/dt, sinus)
•
malfunction
The charging switch is
closed and the feedback
information is OPEN.
operation malfunction
•
defective component
•
Defective IGBT

How to correct the fault
Do a check of the loading.
Do a check of the motor.
Do a check of the cables and con-
nections.
Make an identification run.
Set the acceleration time longer
(P3.4.1.2 and P3.4.2.2).
Set the deceleration time longer
(P3.4.1.3 and P3.4.2.3).
Activate the overvoltage controller.
Do a check of the input voltage.
Do a check of the motor cables and
the motor.
Do a check of the filters.
Reset the fault and restart the
drive.
Do a check of the feedback signal
and the cable connection between
the control board and the power
board.
If the fault occurs again, ask
instructions from the distributor
near to you.
This fault cannot be reset from the
control panel.
Make a power down of the drive.
DO NOT RESTART THE DRIVE or
CONNECT THE POWER!
Ask instructions from the factory.
