Voltage follower (MM21051C only)
Instead of using a speed adjust potentiometer, the drive may be
wired to follow an analog input voltage signal that is isolated from
earth ground (Figure 9). The range of this signal is 0 - 6 VDC.
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 isolation, use an
interface device such as Minarik model PCM4 to scale the analog
input voltage.
