7.2.3 Parameterising the Inverter Drives 8400 motec as CAN master
If the initialisation of the system bus and the associated status change from "Pre-operational" to
"Operational" is not effected by a higher-level host, the Inverter Drive 8400 motec can instead be
defined to be a "quasi" master to execute this task.
Configuration of the inverter as CAN master is carried out in C00352
.
• As CAN master, the inverter sets all
nodes connected to the bus (broadcast telegram) to the
"Operational" communication status by means of the NMT telegram "Start Remote Node". This
is the only communication status allowing for data exchange via the process data objects.
• C00356/1
can be used to set a delay time, which has to pass after mains switching before the
inverter applies the "Start Remote Node" NMT telegram on the bus.
 Tip!
Master functionality is only required during the initialisation phase of the drive system.

 Note!
The changes of the master/slave operation in C00352 will only be activated
• when mains switching of the inverter takes place again
or
• by transmission of the "Reset Node" NMT telegram or "Reset Communication" to the
inverter.
The "CAN reset node" device command (C00002/26) is provided as an alternative to the
"Reset node" NMT telegram for the reinitialisation of the CAN-specific device
parameters.
