10.3 FAULT CODES
Fault
code
Fault ID Fault name Possible cause How to correct the fault
1 1 Overcurrent
(hardware 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 connections. 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
(hardware fault)
The DC-link voltage is
higher than the limits.
•
too short a
deceleration time
•
high overvoltage spikes
in the supply
Set the deceleration time longer
(P3.4.1.3 and P3.4.2.3). Use the
brake chopper or the brake
resistor. They are available as
options. Activate the overvoltage
controller. Do a check of the input
voltage.
11 Overvoltage (software
fault)
3 20 Earth fault (hardware
fault)
The measurement of
current tells that the sum of
the motor phase current is
not zero.
•
an insulation
malfunction 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
circuit in the IGBT
•
a short circuit or an
overload in the brake
resistor
This fault cannot be reset from the
control panel. Switch off the power.
DO NOT RESTART THE DRIVE or
CONNECT THE POWER! Ask
instructions from the factory.
