- Diameter and radius values
The workpiece coordinate system shift amount depends on diameter
programming or radius programming.
Example) Although the base point should be positioned at X =
φ120.0 (diameter value) and Z = 70.0 from the workpiece
zero point, the actual position is at X = φ121.0 and Z =
69.0 from the zero point. Set a shift amount as shown
below:
X=1.0, Z=-1.0

# 0 ZPR Automatic setting of a coordinate system when the manual reference
position return is performed
0: Not set automatically
1: Set automatically
NOTE
ZPR is valid while a workpiece coordinate system
function is not provided. If a workpiece coordinate
system function is provided, making a manual
reference position return always causes the
workpiece coordinate system to be established on
the basis of the workpiece zero point offset
(parameters No. 1220 to No. 1226), irrespective of
this parameter setting.
