3.3 Assignment of the I/O terminals
In the following tables the Lenze assignment of the I/O terminals for the "Regenerative
power supply module" application is listed.
 If required, the default signal configuration can be easily reconfigured via the
parameterisation dialog on the Application parameters tab, or via parameterisation of
the multiplexer parameters assigned.

Terminal Signal (Lenze setting) Signal configuration
X4 DO1 "Ready for regenerative feedback" state
• Mains voltage is applied.
• Charging of DC bus is completed.
• There is no short circuit or earth fault.
• There is no device overload, i.e. the device utilisation ( C00064 ) is
below the warning threshold set in C00123 .
C03100/1
DO2 "Filter overtemperature" state C03100/2
DO3 "Fault active - acknowledgement required" state
• A monitoring function with the "Fault" response has been triggered
and the regenerative power supply module is in the "Fault active"
device state.
C03100/3
DO4 "Warning active" state
• A filter overload or device overload warning has occurred or another
monitoring function with the "Warning" error response has been
triggered and the regenerative power supply module is in the
"Warning active" device state.
