8.1.1
Specification of Limit Switch
1. The interference limit switch at S-, L- and U-axes electrically limit the
operating range of respective axes by adjusting the position of the dog
using the limit switch.
The positions of the mechanical limits (mechanical stoppers) at S-, L-
and U-axes are changeable.
When the limit switch is activated, the power supply to the manipulator
is interrupted, then the manipulator makes an emergency stop as a
result. Refer to section 8.9 “Overrun/Tool Shock Sensor Releasing” in
“DX200 INSTRUCTIONS” for releasing the status of this overrun.
2. The range of S-, L- and U-axes limit switches are set to the maximum
operating range before shipping.
8.1.2
Position of Limit Switch
The limit switches are optional. For the S, L, and U-Axes with limit
switches specifications, L.S. are located on S-Axis, L-Axis, and U-Axis
respectively.
For the location, refer to
Fig. 8-1 “Location of Limit Switches”
. The
inspection and adjustment of the limit switches should be made after
removing the cover.

NOTE
In case of re-adjusting the operating range of each subject
axis, it is also required to change the dog location and limit
values in software. Contact your YASKAWA representative
if re-adjustment is required.
