What I/O needs to be set up to operate unit in PI control for the 8839 Econoflex?

The Econoflex is designed to receive a speed signal in the automatic mode. If PI setpoint process control is desired, it should be provided externally.
Econoflex drives are not designed with PI control in mind. It is not a simple task to convert the drive to allow PI control. Wiring changes, additional I-O and programming are likely necessary. There may be loss of some functionality as a result of the modifications. Thorough knowledge of the existing wiring scheme and PI control operation is necessary.
Please provide external PI control or call SquareD Drives Product Support at 888-SQUARED.
Normal staffing hours are 8 am - 6 pm Eastern US time, Monday - Friday, non-holidays.
