A short overview:
|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|
|Hold-to-run or Deadman switch||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.
|Test mode with reduced speed||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.|
|Pressure sensitive matt||Supervising the danger area.|
|Torque monitoring||Collision detection via torque monitoring|
|Electric skin||no pic||Contact with the housing is detected.|
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 '.
