OK. You need to replace this with a VFD that can accept an analog current input signal.
Given the motor, what he really needs is a clutch control that accepts an analog input. Just popping on a VFD won't control the clutch.
The important question is the application. Is this really being used for speed control, or is its main purpose in torque limiting, and speed control is a side benefit?
