Voltage follower configuration
Connections
Instead of using a speed adjust potentiometer, the drive may be wired to follow a 0–5
VDC voltage signal that is isolated from earth ground (Figure 6 & 7). 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 (see page 7 & 8).
Do not connect a non-isolated input voltage signal to any XP Series
drive. Connecting a non-isolated signal will damage the drive.
