3.1.3 Wiring
[1] Power Supply Connector (for Power Supply and Emergency Stop)
As an example of a circuit, cases of 4 conditions are shown. Select from 3) or 4) for CGB type.
1) Activate the stop switch on the teaching pendant to activate an actuator
● Example of Circuit
The emergency stop input to the controller gets inactivated by supplying +24V continuously to
EMG- Terminal. +24V is connected to EMG- via the emergency stop switch on the teaching
pendant.

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.
● 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.
