Description
Selects the DDCS channel used for connecting an
external controller (such as an AC 800M or ACS880
inverter).
None (communication disabled).
Channel A on FDCO module in slot 1.
Channel A on FDCO module in slot 2.
Channel A on FDCO module in slot 3.
Channel B on FDCO module in slot 1.
Channel B on FDCO module in slot 2.
Channel B on FDCO module in slot 3.
Connector XD2D.
Channel 0 on RDCO module (with UCU control unit only). 11
Selects the node address for communication with the
external controller. No two nodes on-line may have the
same address.
Node address.
Selects the topology of the fiber optic link.
The devices are connected in a ring topology.
Forwarding of messages is enabled.
The devices are connected in a star topology (for
example, through a branching unit). Forwarding of
messages is disabled.
Defines the communication speed on the fiber optic
link. This should be set to the same value on all devices
on the link.
1 Mbps.
2 Mbps.
4 Mbps.
8 Mbps.
Defines the light intensity of the transmission LED of
RDCO module channel CH0. (This parameter is effective
only when parameter 160.51 DDCS controller comm port
is set to RDCO CH 0. 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.
Light intensity.
Sets a time-out for communication with the external
controller. If a communication break lasts longer than
the time-out, the action specified by parameter
DDCS controller comm loss action
Time-out for communication with external controller.
Selects how the supply unit reacts to a communication
break between it and the external controller.
No action taken.
Supply unit trips on 7E11 DDCS controller comm
Supply unit generates an
loss warning. This occurs even though no control is
expected from the external controller.
WARNING! Make sure that it is safe to continue
operation in case of a communication break.
