9.4.4 Configure device as mini master
If the initialisation of the CANopen network and the associated status change from "Pre-
Operational" to "Operational" is not effected by a higher-level host system, the inverter can
instead be defined as a "mini" master to execute this task.
Details
The inverter is configured as mini master in
In the default setting, the inverter is configured as slave and waits for the NMT telegram
•
"Start Remote Node" from the master/host system after being switched on.
Configured as mini master, the inverter changes to the "Operational" state after being
•
switched on and sets all nodes connected to the CAN bus (broadcast telegram) to the
"Operational" communication state using the "Start Remote Node" NMT telegram after
the deceleration time set in
status enables data exchange via the process data objects.
The change of the master/slave operation only becomes effective by renewed
mains switching of the inverter or by sending the NMT telegram "Reset Node"
or "Reset Communication" to the inverter. Alternatively, the CAN communica-
tion can be restarted via

Info
1 = after mains switching, inverter starts as mini-master.
If the inverter has been defined as mini-master, a delay time can be set
here, which has to elapse after mains switching before the inverter
deposits the "Start Remote Node" NMT telegram on the CAN bus.
