8.5.3.1. CANopen initialisation
If the initialisation of the CANopen network and the associated status change from
"PreOperational" 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 0x2301:003 (P510.03).
• 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 0x2301:004 (P510.04) has elapsed. Only this
communication 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 communication can be restarted via 0x2300 (P508.00). Resetting the
CANopen interface

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.
