3. Shift coordinates
Use the cursor keys to select [Edit] on the initial screen, and press the ENTER key. Next, select [Shift
Coordinate], and then press the ENTER key to display the "SHIFT COORDINATE" screen.
In this hierarchy, you can display, edit, or set the shift coordinates and shift coordinate range.
However, when using SCARA type robots, the standard coordinates need to be set.
For details about how to set the standard coordinates, refer to "8. Standard coordinates" in this Chapter.
The robot work position specified by point data on the Cartesian coordinates ("mm" units) can be shifted by
setting the shift coordinates. The movement range can also be limited in each direction.
40 shift coordinates, the shift coordinate number is between 0 and 39, can be set. Shift coordinates are set by
shifting the standard coordinates in the X-direction, Y-direction, Z-direction, and R-direction (rotation of XY
plane).

Data format of shift coordinates
Sn:
1 [ dX ] : ± #####.###(mm)
2 [ dY ] : ± #####.###(mm)
3 [ dZ ] : ± #####.###(mm)
4 [ dR ] : ± #####.###(degree)
(n = 0 to 39)
NOTE
• "n" corresponds to the shift coordinate number. Up to 40 shift coordinates can be set.
Example): S1…Shows the shift coordinate S1.
• When the shift amounts are "dX = 0.00", "dY = 0.00", "dZ = 0.00", and "dR = 0.00", the shift coordinates equal the
standard coordinates.
• When using multiple robots, the shift data is used commonly. The shift number can also be set individually for
each robot.

Additionally, as the shift coordinate range is set, the robot movement range is limited by each shift coordinate.
Furthermore, as the soft limit parameter is set, the robot movement range can be specified more accurately.

Data format of shift coordinate range
• Shift coordinate range (plus) side SHIFT+
• Shift coordinate range (minus) side SHIFT-
1 [ dPX ] : ± #####.###(mm)
1 dMX : ± #####.###(mm)
2 [ dPY ] : ± #####.###(mm)
2 dMY : ± #####.###(mm)
3 [ dPZ ] : ± #####.###(mm)
3 dMZ : ± #####.###(mm)
4 [ dPR ] : ± #####.###(degree)
4 dMR : ± #####.###(degree)
(n = 0 to 39)
NOTE
• "n" is a shift coordinate number. Up to 40 shift coordinates can be set.
• When both the plus side and minus side are "0.00", the movement range is not limited by each axis (x, y, z, r).
