Move command for amplitude points of weaving interpolations is “WEAVEP”.
4-8-2. Change speed
Specify the robot travel speed of the tool center point (arc start
point).
Use the icon on the menu bar to switch the speed range.
L Speed (Low)
M Speed (Middle)
H Speed (High)
4-8-3. Wrist calculation (CL number)
Moving the three wrist axes (RW, BW and TW axes) to a certain position can result in what is called “singular orientation
of the robot, which can cause flip-over of the axes. In order to avoid possible flip-over of the axes, specify a calculation
type of interpolation (the CL number).
CL No.
Calculation (application)
0
Automatic calculation
1
Suitable in circular interpolation if the arc plane and the
tool vector create nearly at right angles (tolerance: within
10 degrees).
2
Suitable in circular interpolation if the arc plane and the
tool vector do not create right angle (more than 10
degrees from right angle).
3
Suitable where BW axis is nearly 0 degree (i.e. TW axis is
parallel to the RW axis).
It avoids the singular orientation error with the following
restrictions.
Teach the CL=3 section as short as possible.
Tool orientaion may not be stable in the CL=3 section.
Actual robot travel speed may be slower than teach
speed.
