Dual Axis Operation
Chapter 19
19-8
Set Zero
You can perform a set zero operation on the axes in a dual group on an
individual basis. For example, if you have a dual axis named X and it
consists of two axes, X1 and X2, when the set zero operation is executed
through PAL, you must specify which axis in the dual group to set zero.
When the set zero operation is performed on an axis, the current axis
location becomes the new zero point of the coordinate system.
Cutter Compensation
Only one tool diameter can be active at any one time. Any offset created
by cutter compensation affects all axes in the dual group.
Tool Length Offsets
Functionality is the same as for any other axis; independent values can be
entered for each axis in the dual group. A T-word selects the length offset
number, and the tool length offset is activated for each axis. Refer to
chapter 20 for details on activating tool length offsets.
Additional programming for the G10L10 and G10L11 codes are available
when a dual axis is the tool length axis. Since each axis in the dual group
can have separate offset values, the G10 block must contain an individual
name for each axis being assigned a value. Just programming the master
axis name assigns values only to the master axis. Your system installer
assigns axis names to all axes in the dual group in AMP. Refer to your
system installer’s documentation for details.
