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).

• 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)
