1.3.6 Enabling device and hold-to-run functionality
Three-position enabling device
The three-position enabling device is a manually operated, constant pressure
push-button which, when continuously activated in one position only, allows
potentially hazardous functions but does not initiate them. In any other position,
hazardous functions are stopped safely.
The three-position enabling device is of a specific type where you must press the
push-button only half-way to activate it. In the fully in and fully out positions,
operating the robot is impossible.
Note
The three-position enabling device is a push-button located on the teach pendant
which, when pressed halfway in, switches the system to MOTORS ON. When
the enabling device is released or pushed all the way in, the manipulator switches
to the MOTORS OFF state.
To ensure safe use of the teach pendant, the following must be implemented:
• The enabling device must never be rendered inoperational in any way.
• During programming and testing, the enabling device must be released as
soon as there is no need for the robot to move.
• Anyone entering the working space of the robot must always hold the teach
pendant. This is to prevent anyone else from taking control of the robot
without his/her knowledge.
Hold-to-run function
The hold-to-run function allows movement when a button connected to the function
is actuated manually and immediately stops any movement when released. The
hold-to-run function can only be used in manual mode.
How to operate the hold-to-run function for IRC5 is described in Operating
manual - IRC5 with FlexPendant .
