(1) CR750 controller
An example of external emergency stop connection is shown below. Details of arrangement of connectors for
exclusive input/output signals and the pin assignments are shown in the following pages.
Fig. 2-15 ： External emergency stop connection (CR750 controller)
Place the emergency stop switch in an easily operable position, and be sure to wire it
to the emergency stop correctly by refer to
Page 42, "2.2.9 Examples of safety
measures" .
This is a necessary measure in order to ensure safe operation so that the robot can be
stopped immediately by pressing the emergency stop switch in the event that the
robot malfunctions.

*1) This terminal is opened at factory shipping (unconnected). If power supply inside the controller is used, short-circuit the terminal.
*2) This terminal can be used only for the external emergency stop input to the controller. The terminal cannot be used for the output
signal of OP emergency stop or TB emergency stop because the controller's internal circuit contains the input detection circuit
and a capacitor.
(Do not use the terminal for other purposes such as monitoring the test pulse outputs, or a false detection may occur.)
