OVER VOLTAGE
The motor controller indicates the DC level is
too high.
If the power is on, be very careful when
working on the machine.
Switch off the machine for at least 0 seconds to
ensure the motor controller has been completely
reset. Then try to start the machine again. If the
error returns, troubleshoot as follows:
1. Verify the voltage supply (230/400 V) to the motor
controller at the contactor X311.
Voltage too high
Voltage OK
The motor controller is
probably defective.
2. Inspect the power supply (230/400 V) at the main
power switch Q1 on the machine.
Voltage too high
Voltage OK
Defective cabling
.
Troubleshoot the mains.
