CMPH contactless controller
4x capacitance over-excitation
The CMPH controller is the highest speed operating controller developed for high frequency and high precision operation of electromagnetic clutches/brakes.
The controller adopts a 4x capacitance excitation method using power transistors as the switching element, making it contactless. This allows us to achieve incredible position control, size control, indexing control and high frequency activation/braking control. A special switching circuit (Patent pending) is used for the controller's internal circuitry, eliminating the need for an external serial resistor.

External connection diagram

1 PS terminal is for switching CL/MB by external power source. See the operation manual for details
2 F terminal is for freeing CL/MB by an external signal. See the operation manual for details
3 Only several mA current can flow for external signal so that use the appropriate signal for that
