Robot Teach Pendant with Emergency Stop

Because an emergency-stop has to be always approachable it is also a part of the control panel. Activating an emergency-stop leads to an immediately stop of all drives of the robot.

Robot Safety Cell

Burst proof Plexiglas pane also protects from accidentally thrown work pieces. The contact for verifying the door of the safety cell is normally integrated within the emergency-loop

Only important for the programming mode or manual mode (safety cell can be opened):
The drives of the robots can only be activated if this switch is in mid-position.

For certain applications, like a test run of a program, the robot should move in slow motion. A selector switch is usually integrated within the hand-hold programming device.

Note: What is a free-turning device of a robot?

With the free-turning device, it is possible to move the robot axes by muscle power for example to free a trapped person. For this purpose, the control system must be shut down before.

Choice of different modes

For certain applications it is necessary to drive the robot in a reduced speed. Examples would be the teach-in programming, if you are close to the robot or the test run of a new program. Each robot, even with simple control, therefore, has at least two modes, namely, HAND 'and' AUTO '.
