LEESON FHP Series Chassis Mount Variable Speed Drives - Manual (Page 42)

32 Installation
Voltage Follower Connections
Instead of using a speed adjust potentiometer, the drive
may be wired to follow a 0 - 5 VDC isolated voltage signal
(Figure 19). Connect the signal input (+) to S2 and signal
common (-) to S1. Make no connection to S3. A
potentiometer can be used to scale the analog input
voltage. The FHP-PCM adder board may be used to scale
and isolate an analog input voltage (see Page 35).
