Remarks
1
Restricted range 1
Safety fence
The outside of the straight line randomly defined from the
center of the robot is a restricted area.
Up to 8 straight restricted lines can be defined.
Up to 4 sets can
be set
It is possible to
switch using the
selection
signal from
safety network.
2
Restricted range 2
Partial range
The partial inside of the area enclosed by straight lines
within the restricted range is defined as a restricted area.
A restricted range can be defined using a maximum of 4
straight lines, and up to 8 locations can be specified.
A three-line triangle or a four-line rectangle can be
specified. For the z direction, the upper and lower limits
can be specified in the world coordinate system.
This function will enabled by general-purpose safety input.
3
Restricted object 1
Restriction on tool
spheres
Specify 20 spheres or cubes for each tool. If the restricted
range is exceeded, set to the condition conforming to the
method of restriction.
4
Restricted object 2
Arm restriction
Specify 10 spheres or cylinders on the robot arm. If the
restricted range is exceeded, set to the condition
conforming to the method of restriction.
5 Tool
Up to 32 tools are supported.
Monitors by the tool number from the robot controller.
Monitor input 4 ch
16 tools are
available
For more, please
use the safety
network function.
6 Restricted
coordination
The world coordinates system in the JIS coordinate is
used for operating range monitoring.
Therefore, for a robot placed on a stand or wall-mounted
robot, specify using “constant: format and initial setting:
installation position”.
