Warning and fault messages
The control panel will display the warnings and faults of the unit (supply or inverter
unit) that the panel is currently monitoring.
Information on warnings and faults concerning the supply unit are contained within
the IGBT Supply Control Program Firmware Manual (3AFE68315735 [English]).
The warnings and faults concerning the inverter unit vary depending on the delivery.
For them, refer to the inverter control program firmware manual delivered with the
drive.
Warning/Fault message from the unit not being monitored by the control panel
Flashing messages WARNING, ID:2 or FAULT, ID:2 on the control panel display
indicate a warning or fault state in the supply unit when the panel is controlling the
inverter unit, for example:
To display the warning or fault identification text, switch the control panel to view the
supply unit as described in section Switching the control panel between the supply
and inverter units on page 114.
Conflicting ID numbers
The ID numbers of the supply unit and inverter unit are defined at the factory. Do not
change the settings. If you change the ID numbers equal by accident, the panel
stops communicating with either of the units. Correct the settings as follows:
Location LED Indication
RMIO board (RDCU drive control
unit)
Red Fault state.
Green The power supply on the board is OK.
Control panel mounting platform
(with the control panel removed)
Red Fault state.
Green The main +24 V power supply for the control panel and the
RMIO board is OK.
AINT board (visible through the
transparent cover on the front of the
supply and inverter modules
V204 (green) +5 V voltage of the board is OK.
V309 (red) Prevention of unexpected start or Safe torque off is ON.
V310 (green) IGBT control signal transmission to the gate driver control
boards is enabled.
