1.5 Emergency Stop

If the Manipulator moves abnormally during operation, immediately press the
Emergency Stop switch. The motor power will be turned OFF, and the arm
motion by inertia will be stopped with the electromagnetic brake and dynamic
brake.
However, avoid pressing the Emergency Stop switch unnecessarily while the
Manipulator is running normally. Otherwise, the Manipulator may hit the
peripheral equipment since the operating trajectory while the robot system stops is
different from that in normal operation.
To place the robot system in emergency mode during normal operation, press the
Emergency Stop switch when the Manipulator is not moving.
Refer to the Controller manual for instructions on how to wire the Emergency Stop
switch circuit.
Do not press the Emergency Stop switch unnecessarily while the Manipulator is
operating. Pressing the switch during the operation makes the brakes work.
This will shorten the life of the brakes due to the worn friction plates.
Normal brake life cycle: About 2 years (when the brakes are used 100 times/day)
Before using the Emergency Stop switch, be aware of the followings.
- The Emergency Stop (E-STOP) switch should be used to stop the
Manipulator only in case of emergencies.
- To stop the Manipulator operating the program except in emergency, use
Pause (halt) or STOP (program stop) commands
Pause and STOP commands do not turn OFF the motors. Therefore, the
brake does not function.
- For the Safeguard system, do not use the circuit for E-STOP.
