Coordinate Control
Chapter 11

To use this feature, follow these directions:
1. Turn on the switch to activate the jog offset function (see
documentation provided by your system installer).
2. Change to manual mode unless the control is equipped for the “Jog
on the Fly” feature, which allows jogging in MDI, and Automatic
modes. If equipped with “Jog on the Fly” turn on the switch to
activate it. For details, see documentation prepared by your system
installer.
3. Jog the axis using any of the available jog types, with the exception
of homing and arbitrary angle jog. The control adds the amount of
the jog move as offsets to each jogged axis immediately when the jog
takes place.
Important: When the jog offset move is made, the axis position displays
do not change on the screen (unless the currently active screen is
displaying absolute position coordinates). This is because the coordinate
values in the work coordinate system are being offset as the axes are being
jogged.
You can cancel the jog offset by programming a G92.1, G92.2, executing a
control reset operation, executing an E-STOP reset operation, or
programming an end of program (M30 or M02, or M99 command).
The G92.1 command cancels these offsets:
G92 work coordinate system offset
G52 zero point offset
{SET ZERO} offset
Jog offset
Reset G54 - G59.3 coordinate systems to default conditions
G92.1 does not cancel an external offset (see page 11-10).
The G92.1 block also re-establishes the default work coordinate system as
set in AMP by your system installer. It cancels or activates the coordinate
system (G54-G59.3) as set in AMP to establish the default coordinate
system.
