Description
Data sets 24 and 25.
Activates DDCS controller communication monitoring
separately for each control location (see section
vs. external control on page 20).
The parameter is primarily intended for monitoring the
communication with the controller when it is connected to the
application program and not selected as a control source by
drive parameters.
Value
1 = Communication monitoring active when Ext 1 is being used.
1 = Communication monitoring active when Ext 2 is being used.
1 = Communication monitoring active when local control is being
used.
DDCS controller communication monitoring selection.
(Only visible when supply unit control activated by 95.20)
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)
None (communication disabled).
Channel 1 on RDCO module.
Connector X201.
(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
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 Specifications of the fiber optic
master/follower link (page 38).
Light intensity.
(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
Timeout for communication between converters.
(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.
No action taken.
