How do I setup my VFD running PID with an HOA switch?

This FAQ contains the necessary parameter settings for using a multi-function (digital) input to switch between PID and a hand reference source.  This operation is common to pumping panels utilizing Hand-Off-Auto (HOA) or selector switches.  This document covers the G100, S100, iS7, and H100 VFDs. 

Note: The setup procedures listed below apply to VFDs that are running the VFD’s internal PID process. There is another Application Note for VFDs not running PID.

G100/S100

  1. Set the desired digital input (IN 65 - 69) to setting 23 (PID Open Loop).
  2. Set the frequency reference source in DRV 07. This is the reference source the drive will use when the "PID Open Loop" digital input is closed.
 iS7
  1. Set the desired digital input (IN 65 - 72) to setting 23 (PID Open Loop).
  2. Set the frequency reference source in DRV 07. This is the reference source the drive will use when the "PID Open Loop" digital input is closed.

H100/H100+

  1. Set the desired digital input (IN 65 - 71) to setting 25 (PID Open Loop).
  2. Set the frequency reference source in DRV 07. This is the reference source the drive will use when the "PID Open Loop" digital input is closed.
