11.3 FAULT CODES
Fault
code
Fault ID Fault name Possible cause How to correct the fault
1 1 Overcurrent (hard-
ware fault)
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
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).
2 Overcurrent (software
fault)
2 10 Overvoltage (hard-
ware fault)
The DC-link voltage is
higher than the limits.
•
the deceleration time is
too short
•
high overvoltage spikes
in the supply
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.11 Overvoltage (software
fault)
3 20 Earth fault (hardware
fault)
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
Do a check of the motor cables and
the motor.
Do a check of the filters.
21 Earth fault (software
fault)
5 40 Charging switch The charging switch is
closed and the feedback
information is OPEN.
•
operation malfunction
•
defective component
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.
7 60 Saturation
•
Defective IGBT
•
de-saturation short cir-
cuit in the IGBT
•
a short circuit or an
overload in the brake
resistor
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.
