12.9.2.4 Conguring the device as mini master
If the inialisaon of the CANopen network and the associated status change from "Pre-
Operaonal" to "Operaonal" is not eected by a master (PLC), the inverter can instead be
dened as a "mini master” to execute this task.
Details
The inverter is congured as mini master in 0x2301:003 (P510.03).
•
In the default seng, the inverter is congured as slave and waits for the NMT telegram
"Start Remote Node" from the master (PLC) in the "Pre-Operaonal" state aer being
switched on.
•
Congured as mini master, the inverter changes to the "Operaonal" state aer being
switched on and sets all nodes connected to the CAN bus (broadcast telegram) to the
"Operaonal" communicaon state using the "Start Remote Node" NMT telegram aer
the deceleraon me set in 0x2301:004 (P510.04) has elapsed. Only this communicaon
status enables data exchange via the process data objects.
The change of the master/slave operaon only becomes eecve by renewed
mains switching of the inverter or by sending the NMT telegram "Reset Node"
or "Reset Communicaon" to the inverter. Alternavely, the CAN communica-
on can be restarted via 0x2300 (P508.00).

If the inverter has been dened as mini-master, a delay me can be set
here, which has to elapse aer mains switching before the inverter
deposits the "Start Remote Node" NMT telegram on the CAN bus.
