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.

Caution
When supplying the power by turning ON/OFF the 24V DC, keep the 0V being
connected and have the +24V supplied/disconnected (cut one side only). Shutting
power supply on the both ends may make the electric potential unstable when the
power gets cut on the 0V end first. This may cause malfunction of components inside
the controller.
The rating for the emergency stop signal (EMG-) is 24V DC and 10mA or less.
Leave for 1s or more after shutting the power off before rebooting.
Do not attempt to supply only the motor power without supplying the control power.
The safety categories complied type (CGB/CGFB/CGBP Type) is not equipped with the
relay to have the controller automatically identify that a teaching tool was plugged in
and switch the wiring layout. Those other than the safety categories complied type do
the automatic identification.
For safety categories complied type, install an external circuit that shuts off the motor
drive source.
There could be a case that the voltage supplied to the controller drops due to cable
diameter or length, which may generate an alarm. In this case, it is necessary to adjust
the output voltage on the power so the voltage supplied to the controller gets to 24V.
