3.4.2.2 Defining a master in a drive group C0352
If information is exchanged between one drive and another in a drive group, without a higher-level
control system being present to provide the master function, then one drive controller must be
defined as the master.
The following assignments are valid:
• C0352 = 0: drive is slave (factory setting)
• C0352 = 1: drive is master
The master functionality is only required for the initialisation phase of the drive system.
The master effects a change of state from Pre-Operational to Operational.
An exchange of data through process-data objects is only possible in the Operational state.

In addition, you can define a Boot-Up time for the master during the initialisation phase.
