Single speed potentiometer control of
multiple drives
Multiple drives can be controlled with a single speed adjust
potentiometer using a PCM4 at the input of each drive to provide
isolation (Figure 16). Optional ratio potentiometers can be used to
scale the PCM4 output voltage, allowing independent control of
each drive.
