A short overview:

Emergency-Stoprobot emergency stop - Safety devicesBecause 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.

Safety-cellrobot safety cell - Safety devicesBurst 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
Hold-to-run switchrobot hold to run switch Kopie - Safety devicesOnly 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.
Test mode with reduced speedrobot teach panel - Safety devicesFor 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.
Pressure sensitive mattrobot pressure sensitive matt - Safety devicesSupervising the danger area.

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 '.
