Figure 32. Single Speed Potentiometer Control of Multiple Drives
Multiple drives can be controlled with a single speed adjust potentiometer
using a USIM-8 at the input of each drive to provide isolation (Figure 32).
Optional ratio potentiometers can be used to scale the USIM-8 output
voltage, allowing independent control of each drive.
