Clutches and Brakes

FMPR type controller

Controller dedicated for ERS/EPR

A contactless controller dedicated for control only clutches, brakes and cell pack series brakes. The basic circuit consists of power, power switching, and operation control.
A contactless method utilizing power transistors is used for the switching of clutches/brakes with the inverse excitation current being applied on the clutch at the moment of releasing and on the brake at the moment of attraction. It is also possible to adjust the brake release voltage. This device only requires an AC input, clutch/brake and external signal (push button switch, relay contact, transistor, and the proximity relay etc.) connections to function.

1. The capacity shows the total capacity of the clutch/brake
2. It is not necessary to connect a varistor as a discharge circuit.

External connection diagram

1. PS terminal is for switching CL/MB using an 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 current of several milliamps can be used for the external signal so ensure an appropriate input.
