Figure 16. Single Speed Potentiometer Control of Multiple Drives
Single speed potentiometer control of
multiple drives
Multiple drives can be controlled with a single speed adjust
potentiometer using a 174335 Process Control Module (PCM) at
the input of each drive to provide isolation (Figure 16). Optional
ratio potentiometers can be used to scale the PCM output
voltage, allowing independent control of each drive.
