SPECIFICATIONS
The ICM708 will control the speed of a GE 2.3 Electronically
Commutated Motor (ECM). The user controls the flow index
percentage via an onboard potentiometer, from 0-100%. The
motor provides feedback to the control via pulses on the RPM
input. The requested flow index percentage is alternately
displayed with the motor’s RPM.
