Instead of using a speed adjust potentiometer, the drive may be
wired to follow a voltage signal that is isolated from earth ground
(Figure 6). Use an analog voltage range of 0 - 2.7 VDC with 115
VAC line voltage. Use an analog voltage range of 0 - 5 VDC with
230 VAC line voltage.
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. To achieve greater linearity and
control, use an interface device such as Minarik model PCM4 to
scale the analog input voltage. Follow the same wiring guidelines
used for speed adjust potentiometer wiring.
