Leader-follower application
In this application, use a 174335 Process Control Module (PCM)
to monitor the speed of the leader motor (Figure 15). The PCM
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 PCM output voltage.
