Example parameter settings
The following is a checklist of parameters that need to be set when configuring the
master/follower link. In this example, the master broadcasts the Follower control word,
a speed reference and a torque reference. The follower returns a status word and two
actual values (this is not compulsory but is shown for clarity).
Master settings
• Master/follower link activation
•
60.1 M/F communication port (fiber optic channel or XD2D selection)
•
(60.2 M/F node address = 1)
•
60.3 M/F mode = DDCS master (for both fiber optic and wire connection)
•
60.5 M/F HW connection (Ring or Star for fiber optic, Star for wire)
• Data to be broadcast to the followers
•
61.1 M/F data 1 selection = Follower CW (Follower control word)
