PHASE MISSING
The DC voltage level fluctuates too much.
If the power is on, be very careful when wor-
king 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 (400 V) to the motor
controller at the contactor X311.
Large voltage fluctuations
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.
Large voltage fluctuations
Voltage OK
Defective cabling

Troubleshoot the mains.
