• Indicator
• Control Power ON/OFF
To turn ON the robot controller power, turn ON the non-fuse breaker of the controller so
that the control power supply is turned ON. If the controller is not located at the
workplace, the control power supply can be turned ON/OFF by an external device, etc.
after the non-fuse breaker of the controller is turned ON. It is operated by the external
switch connected with CN152 of the Control power supply unit as shown in the following
figure (CN152-1 and CN152-2 is shortaged when shipment).
See chapter 8.25 "Brake control circuit board (JANCD-YBK21-3E)" at page 89 for wiring of
CN152 connector.
