Clutches and Brakes

CSM type controller

4x over excitation on a printed circuit board

The CSM controller is a contactless controller for electromagnetic clutches/brakes. This controller uses a 4x over-excitation method and a time lag circuit, realizing excellent performance which is suitable for high frequency operation. Also by mounting the parts on a printed circuit board, we can achieve a smaller footprint and lower the cost at the same time.

1. Don't connect a varistor as a discharge circuit.
2. AC 45-110V can be used as the * signed over excitation input voltage. In this case, the over excitation output voltage varies roughly proportionally.

External connection diagram

1. PS terminal is for switching CL/MB by an external power source. See the operation manual for details.
2. Only current of several milliamps can be used for the external signal so ensure an appropriate input.

About the external (input) power source

See the figure bellow for the category and the connection of the external (input) power source.

Don't connect as is shown below. The internal elements will be instantaneously destroyed.
