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.

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.

 A delay time can be set in C00356/1

, which must expire after mains switching before

the controller transmits the "Start remote node" NMT telegram.

 Tip!

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

system.

Value Unit

C00352 CAN slave/master Slave

C00356/1

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

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

transmitted to the controller.

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.
