4) Shut off the motor power externally when emergency stop switched ON with using two units of
controllers or more
● Example of Circuit
Note 1 : The safety categories complied type (CGB/CGFB 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 and have S1 and S2 short-circuited.
Note 2 : When the motor driving source is cut off externally for a compliance with the safety
category, connect a contact such as a contactor to the wires between MPI and MPO.
Refer to [9.2 Conformity to Safety Category]
Note 3 : The rating for the emergency stop signal (EMG-) to turn ON/OFF at contact CR1 is
24V DC and 10mA or less.
Note 4 : For CR1, select the one with coil current 0.1A or less.

Caution
● If supplying power with using a 24V DC, having it turned ON/OFF, keep the 0V
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.
● When rebooting after shutting down, leave for 1s or more.
● 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.
