World Zones
A spherical, cylindrical or cubical volume can be defined within the working space.
When the robot reaches this volume it will either set an output or stop with the error
message "Outside working range", both during program execution and when the robot
is jogged into this area. The areas, which are defined in the world coordinate system,
can be automatically activated at start-up or activated/deactivated from within the
program.
Examples of applications:
- A volume is defining the home position of the robot.
When the robot is started from a PLC, the PLC will check that the robot is
inside the home volume, i.e. the corresponding output is set.
- The volume is defining where peripheral equipment is located within the work-
ing space of the robot.
This ensures that the robot cannot be moved into this volume.
- A robot is working inside a box.
By defining the outside of the box as a forbidden area, the robot cannot run into
the walls of the box.
- Handshaking between two robots both working in the same working space.
When one of the robots enters the common working space, it sets an output and
after that enters only when the corresponding output from the other robot is
reset.
