Coordinate Control
Chapter 11
11-22
The G92.2 command cancels these offsets:
G92 work coordinate system offset
{SET ZERO} offset
Jog offset
G92.2 does not cancel an external offset (see page 11-10), reset the current
work coordinate system (G54-G59.3) or cancel a G52 offset.
You must program the G92.2 block with no axis words. Axis words in a
G92.2 block generate an error. When the control executes the G92.2
block, the control cancels all G92, {SET ZERO}, and Jog offsets on all
axes. You cannot cancel the offsets on individual axes.
No axis motion takes place during execution of a G92.2 block. Axes
remain at their last programmed position while the work coordinate system
is adjusted to remove these offsets.
Your system installer has the option to activate, deactivate, or alter the
value of these offsets through PAL:
Work coordinate systems
External offset
Wheel length offsets
Dresser/wheel radius offsets
Wheel orientation
Your system installer can modify these offsets through a PAL display page
created by your system installer or through some other input to PAL.
Be aware that there can be an impact to the activation of offsets if a part
program is already active for automatic execution. Typically, any blocks
that have been read into the control’s look-ahead buffer use the newly
modified offset value. However, if a dresser/wheel radius compensation
offset has been modified by PAL, the control does not update the
look-ahead buffer. See documentation supplied by your system installer
for details on specific PAL offset operations.
