EMP contactless 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
(Note)
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.
