Emergency Stop - Epson ProSix S5 Series Manual

Setup & Operation 1. Safety

1.4 Emergency Stop

If the Manipulator moves abnormally during operation, immediately press the Emergency
Stop switch. It stops the power supply to the motor, and the arm stops in the shortest
distance with the dynamic brake and mechanical 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. It may also reduce the life of the reduction gear unit by the shock, or reduce
the life of the electromagnetic brake by worn friction plate.
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.
