Clutches and Brakes

EMP type controller

2x over-excitation

The EMP controller is a contactless controller used for electromagnetic clutches/brakes. It uses a 2x over-excitation method and a time lag circuit to achieve very stable operation even when high frequency and high precision is required. Additionally, it uses a fully contactless technique circuit configuration utilizing power transformers, yielding high performance and long operating life.

EMP-20DB

RH1: Control to adjust the time lag from brake to clutch.
RH2: Control to adjust the time lag from clutch to brake.
RH3: Control to adjust over-excitation time (Both for clutch and brake)

EMP-70DB

SW1: Switch between 2 signals and single signal (ON: mono signal)
SW2: Switch between a voltage signal and non-voltage signal (ON: voltage signal)
SW3: Switch between alternating operation of clutch and brake or single operation (ON: single operation)

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.
