Program features 31
Master/follower functionality
General
The master/follower functionality can be used to link several drives together so that
the load can be evenly distributed between the drives. This is ideal in applications
where the motors are coupled to each other via gearing, chain, belt, etc.
The external control signals are typically connected to one drive only which acts as
the master. The master controls up to 10 followers by sending broadcast messages
over an electrical cable or fiber optic link. The master can read feedback signals from
up to 3 selected followers.
