Wire Connection Required to Prepare a Robot and RC8A (Safety-I/O-Less Controller)

This section shows the minimum wire connection required for the stand-alone robot unit to turn the motor power ON or run in Auto or Manual mode during adjustment in starting up the robot system.

Configuration of Emergency Stop Circuitry

The External Emergency Stop and Enable Auto input signals are important for safety. Be sure to configure their circuits with contacts as shown below.

Wire Connection Required for Motor ON

Short-circuiting both the Emergency Stop input circuits (dual line) only enables the motor to turn ON.

Input signal name Terminal number
External Emergency Stop 1 #2 and #36 on connector CN5
External Emergency Stop 2 #3 and #37 on connector CN5

The different status between two emergency stop circuits, if kept for at least approx. one second, will be interpreted as an occurrence of trouble, triggering an error "One of the external emergency stop
line is disconnected."

Wire Connection Required for Automatic Operation

  1. Turning this signal ON (shorting) enables switching to Auto mode.
  2. Turning this signal OFF (opening) enables switching to Manual or Teach check mode.
Input signal name Terminal number
Enable Auto #1 and #35 on connector CN5
Protective Stop 1 #4 and #38 on Mini I/O connector
Protective Stop 2 #5 and #39 on Mini I/O connector

If no Protective Stop input signals are needed, their circuits can be always short-circuited by terminal connection with jumpers between #4 and #38 and between terminals #5 and #39 on Mini I/O connector.
