Node-ID: The Node-ID indicates the address of the
CD1-k
(defined by switches). If Node_ID = 0, the protocol
addresses all NMT slaves.
2.1.4 - SYNCHRONISATION OBJECT (SYNC)
The SYNC object is a broadcast message sent by the master. This message provides a network clock. The period
is specified by the communication cycle period (object 1006h). The Infranor servo-drives use this SYNC message
to synchronize their clock.
At least 180 ms are necessary for the servo-drive to start the synchronisation.
