Fault tracing
Faults and warnings displayed by the CDP-312R Control Panel
The control panel will display the warnings and faults of the unit (i.e. supply unit or
inverter unit) the panel is currently controlling.
Information on warnings and faults concerning the supply unit (line-side converter)
are contained within the IGBT Supply Control Program Firmware Manual
(3AFE68315735 [English]).
The warnings and faults concerning the inverter unit (motor-side converter) are dealt
with in the inverter control program (e.g. Standard Control Program) Firmware
Manual.
Warning/Fault message from unit not being monitored by control panel
Flashing messages WARNING, ID:2 or FAULT, ID:2 on the control panel display
indicate a warning or fault state in the line-side converter when the panel is
controlling the motor-side converter:
To display the warning or fault identification text, switch the control panel to view the
line-side converter as described in section Control panel on page 40.
Conflicting ID numbers
If the ID numbers of the line-side and the motor-side converters are set equal, the
control panel stops functioning. To clear the situation:
• Disconnect the panel cable from the RMIO board of the motor-side converter.
• Set the ID number of the line-side converter RMIO board to 2. For the setting
procedure, see the inverter control program (e.g. Standard Control Program)
Firmware Manual.
• Connect the disconnected cable to the RMIO board of the motor-side converter
again and set the ID number to 1.
