Voltage follower
Instead of using a speed adjust potentiometer, the drive may be
wired to follow an isolated (floating, or differential) 0–10 VDC signal
that is isolated from earth ground (Figure 8). Connect the signal
input (+) to S2. Connect the signal common (–) to S1. Make no
connection to S3. A potentiometer can be used to scale the analog
input voltage.
