10.2 FAULT CODES
Fault
code
Fault
Subcode in
T.14
Possible cause How to correct the fault
1 Overcurrent S1 = Hard-
ware trip
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
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.
S2 =
Reserved
S3 = Cur-
rent con-
troller
supervision
2 Overvoltage S1 = Hard-
ware trip
The DC-link voltage is
higher than the limits.
•
too short a decelera-
tion time
•
high overvoltage spikes
in the supply
•
Start/Stop sequence
too fast
Set the deceleration time longer.
Use the brake chopper or the brake
resistor. They are available as
options.
Activate the overvoltage controller.
Do a check of the input voltage.
S2 = Over-
voltage
control
supervision
3 * Earth fault The measurement of cur-
rent tells that the sum of the
motor phase current is not
zero.
•
an insulation malfunc-
tion in the cables or the
motor
Do a check of the motor cables and
the motor.
5 Charging switch The charging switch is open,
when the START command
is given.
•
operation malfunction
•
defective component
Reset the fault and start the drive
again.
If the fault shows again, ask
instructions from the distributor
near to you.
6 Emergency stop Stop signal has been given
from the option board.
Do a check of the emergency stop
circuit.
7 Saturation trip
•
defective component
•
brake resistor short-
circuit or overload
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.
If this fault shows at the same time
with Fault 1, do a check of the
motor cable and the motor.
