FAULT TRACING
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 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.
Do a check of the motor cables and
the motor.
Reset the fault and start the drive
again.
If the fault shows again, ask
instructions from the distributor
near to you.
Do a check of the emergency stop
circuit.
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.
