32 InstallationVoltage Follower ConnectionsInstead of using a speed adjust potentiometer, the drivemay be wired to follow a 0 - 5 VDC isolated voltage signal(Figure 19). Connect the signal input (+) to S2 and signalcommon (-) to S1. Make no connection to S3. Apotentiometer can be used to scale the analog inputvoltage. The FHP-PCM adder board may be used to scaleand isolate an analog input voltage (see Page 35).TB501SIGNAL INPUT (+)SIGNAL COMMON (-)0 TO + 5 VDC VOLTAGE SIGNALE2E1S1S2DS3Figure 19.
