Emergency Stop Control Circuit
Brake Release Power Supply
(Note) When connecting actuator equipped with brake
supply 24V power to forcibly release the brake.
Note 1 : When the teaching pendant is not connected, S1 and S2 become short-circuited inside the
controller.
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 Chapter 9 Appendix]
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.
Note 5 : When rebooting after shutting down, leave for 1sec or more.
Caution : If supplying power with using a 24V DC, having it turned ON/OFF, keep the 0V
connected and have the +24V supplied/cut (cut one side only).
