Selects the DDCS channel used for connecting to another
converter (such as a supply unit).
The selections available, as well as the default, depend
on drive hardware.
See also section Control of a supply unit (LSU) (page 45).

10 / uint16
(Only visible when supply unit control activated by 95.20)
Defines the light intensity of the transmission LED of RDCO
module channel CH1. (This parameter is effective only
when parameter 60.71 INU-LSU communication port is set
to RDCO CH 1. FDCO modules have a hardware
transmitter current selector.)
In general, use higher values with longer fiber optic cables.
The maximum setting is applicable to the maximum length
of the fiber optic link. See Master/follower
functionality (page 34).

100 ms / uint16
(Only visible when supply unit control activated by 95.20)
Sets a timeout for communication with another converter
(such as the supply unit). If a communication break lasts
longer than the timeout, the action specified by parameter
60.79 INU-LSU comm loss function is taken.

Fault / uint16
(Only visible when supply unit control activated by 95.20)
Selects how the inverter unit reacts to a communication
break between the inverter unit and the other converter
(typically the supply unit).
WARNING!
With settings other than Fault, the inverter unit will
continue operating based on the status information
that was last received from the other converter.
Make sure this does not cause danger.
