function
DDCS (fiber optic)
communication between
converters (for example, the
inverter unit and the supply
unit) is lost.
Note that the inverter unit will
continue operating based on
the status information that was
last received from the other
converter.
Check status of other converter
(parameters 06.36 and 06.39).
Check settings of parameter group 60
DDCS communication. Check the
corresponding settings in the control
program of the other converter.
Check cable connections. If necessary,
replace cables.
