6 Safety
<Wiring example 3>: Using a machine guard and running the robot in high-speed operation mode only
Connect the emergency stop switch of peripheral equipment to the controller. The power supply for emer-
gency stop input uses the power supply in the controller.
<Operation of the emergency stop>
If the emergency stop switch of peripheral equipment is pushed, the robot will also be in the emergency stop
state.
<Operation of Safety input 1>
Closing the terminals will keep the robot in high-speed operation mode.

Internal emergency stop circuit
*1) The CNUSR11 port and SDI1 port both have two rows of terminals, indicating that there are two channels. Both channels must be
connected.
*2) This is the emergency stop switch of the teaching pendant that is connected to the robot controller.
*3) If a Safety extension unit is not connected to the robot controller, the error H2260 "Safety function execution disabled (No extended
safety unit)" will occur.
*4) For examples of safety input 1 connections, refer to the section "Connecting the safety extension unit to the controller" in the sep-
arate manual "Instruction Manual: Controller Setup and Maintenance".
*5) Direct teaching is not available in high-speed operation mode.
