B-Axis Operating Range
The operating range of the B-axis maintaining a constant angle to the
center of U-axis is shown in
Fig. 5-4 “B-Axis Operating Range”
.
By “B-axis adjustable motion function”, the B-axis maintains the same
posture to the ground regardless of the L- or U-axis angle.
The operating range is ±15° (0 degree is defined as the angle when the
wrist flange is horizontal and facing to the ground.) When the B-axis
position exceeds this limit, ”Special Soft Limit” occurs.
Note: In relation with interference with the upper arm, the range of motion
can be limited.
