Application Notes
Leader-follower application
In this application, use a PCM4 to monitor the speed of the
leader motor (Figure 24). The PCM4 isolates the leader motor from
the follower drive, and outputs a voltage proportional to the leader
motor armature voltage. The follower drive uses this voltage
reference to set the speed of the follower motor. An optional ratio
potentiometer may be used to scale the PCM4 output voltage.
