9.5.3 Parameterising the controller 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 superimposed host system, the controller can instead be defined

to be a "quasi" master to execute this task.

The controller is configured as CAN master in C00352

.

• Being the CAN master, the controller sets all

nodes connected to the bus (broadcast telegram)

to the "Operational" communication status with the "Start remote node" NMT telegram. Only

in this communication status, data can be exchanged via process data objects.

•In C00378

, you can set a delay time which must elapse after power-up before the controller

applies the "Start Remote Node" NMT telegram to the bus.

 Tip!

Master functionality is only required during the initialisation phase of the drive system.

Value Unit

C00352 CAN slave/master Slave

C00378

CAN delay boot-up - Operational 3000 ms

 Note!

The changes of the master/slave operation in C00352 will not be activated until

• another mains switching of the controller

or

• the "Reset node" or "Reset communication" NMT telegram has been transmitted to

the controller.

As an alternative to the "Reset Node" NMT telegram, the device command C00002

="91:

CAN on board: Reset Node" can be used to reinitialise the CAN-specific device

parameters.
