9.4.4 Congure device as mini master

If the inialisaon of the CANopen network and the associated status change from "Pre-

Operaonal" to "Operaonal" is not eected by a higher-level host system, the inverter can

instead be dened as a "mini" master to execute this task.

Details

The inverter is congured as mini master in 0x2301:003 (P510.03).

•

In the default seng, the inverter is congured as slave and waits for the NMT telegram

"Start Remote Node" from the master/host system aer being switched on.

•

Congured as mini master, the inverter changes to the "Operaonal" state aer being

switched on and sets all nodes connected to the CAN bus (broadcast telegram) to the

"Operaonal" communicaon state using the "Start Remote Node" NMT telegram aer

the deceleraon me set in 0x2301:004 (P510.04) has elapsed. Only this communicaon

status enables data exchange via the process data objects.

The change of the master/slave operaon only becomes eecve by renewed

mains switching of the inverter or by sending the NMT telegram "Reset Node"

or "Reset Communicaon" to the inverter. Alternavely, the CAN communica-

on can be restarted via 0x2300 (P508.00). 4Restart communicaon ^ 222

deposits the "Start Remote Node" NMT telegram on the CAN bus.
