3) Shut off the motor power externally when emergency stop switched ON
● Example of Circuit
The emergency stop gets released when +24V is supplied to EMG- Terminal on the controller,
and emergency stop activates if the power supply is shut, and stops the actuator operation,
turns the servo OFF and cuts off the motor power supply inside the controller.
+24V supply to the external drive cutoff relay should get shut off when an external emergency
stop switch or an stop switch on the teaching pendant is turned ON. By this, the relay on the
drive cutoff circuit opens and the power supply to the motor gets shut off. At the same time,
+24V supply to EMG- terminal should also be shut off, and the condition should get into the
emergency stop status.
Turn ON the emergency stop reset switch after putting the emergency stop switch back OFF,
and +24V supply to the drive cutoff relay gets conducted. By this, the relay on the drive cutoff
circuit closes and the power supply to the motor gets conducted. At the same time, +24V supply
to EMG- terminal should also be resumed, and the emergency stop status should be cancelled.
