DIAGNOSTICS AND TROUBLESHOOTING
Fault/alarm Reset Possible causes
F0511
Cell U5 electronics power supply
Contact WEG Service Center. Voltages of the internal electronic circuits of the
cell out of the operation level.
Defect on the cell power supply.
F0516
Cell U5 modulation synchronism
Contact WEG Service Center. Fault in the synchronism between the MCC1
control board of the cell and the MVC3 main con-
trol.
F0517
Cell U5 bypass system
Contact WEG Service Center. Fault in the operation of the cell bypass system.
Bypass system is not connected or defective.
F0518
Communication with cell U5
Contact WEG Service Center. Fault on the communication between the MCC1
control board of the cell and the MVC3 main con-
trol.
Break or defect on the cell communication optic
cable.
F0520
Incompatible cell U5 firmware
Contact WEG Service Center. Firmware version of the MCC1 control board of
the cell incompatible with the MVC3 main control.
F0521
Incompatible cell U5 model
Contact WEG Service Center. Cell model incompatible or invalid with the in-
verter model.
F0522
Cell U5 insulation defective
Contact WEG Service Center. Fault in the internal insulation of the cell: Contact
between some energized point of the circuit and
the frame.
Fault on the capacitor discharge resistors of the
cell DC link.
F0523
Firmware update or PLD cell U5
Contact WEG Service Center. Fault in the update process of the processor
firmware or in the reconfiguration of the cell PLD.
F0525
