Wiring Of The Stop Switch - SMC Networks JXC92 Operation Manual

(2) Wiring of the stop switch

A Stop switch must be installed by the user to stop the actuator in abnormal situations. The
actuator stops its operation when the external shutdown switch is activated.
- Stop (Stop switch)
To stop the controller, connect the stop switch (B contact) between the motor drive and motor
control power supply and the EMG terminal of the motor control power supply connector.

- Stop (Stop relay contact)
If there is a separate shutdown circuit for the whole installation or there are multiple controllers
with different power supplies, connect a relay (B contact) between the motor drive and motor
control power supply and the EMG terminal of the motor control power supply connector.
(Circuit example: The Figure below shows the stop status).

When the EMGx input is turned off (0V) during operation, the corresponding actuator will stop with
maximum deceleration and the servo will be turned off there after.
