Turning the Robot Controller ON/OFF

The robot controller supplies the robot unit with power and controls it.To operate the robot, you need to turn on the robot controller.
For safety, turn off the controller before connecting the robot and the controller, replacing parts, or performing internal checks.
To turn on/off the robot, operate the circuit breaker (main disconnecting switch) of the robot controller shown in the figure below.
- Turn it to ON side (clockwise) : turns on
- Turn it to OFF side (anti-clockwise) : turns off
When the robot is on, the POWER LED lamp (the leftmost of the three pilot lamps) in the figure below keeps coming on. When it is turned off, the pilot lamp goes out.
If the motor is on, turn it off before turning off the robot controller.
If you want to turn the robot controller on again immediately after turning it off, "wait one minute or more" after the POWER LED lamp on the robot controller completely goes out.
Be sure to turn the robot controller off before connecting or disconnecting the robot control cable between the robot unit and its controller. Connection/disconnection of the robot control cable while the robot controller power is on will damage the robot controller.
Note that when the power is turned off, the fan will stop once but rotate again for a few seconds immediately afterwards.
