Chapter 11
Coordinate Control
11-13
This section describes the more temporary ways of offsetting the work
coordinate systems. These offsets are activated through programming and
are canceled when a control reset is performed, or power to the control is
turned off. These offsets can also be canceled when the control executes
an end of program command (M02, M30, or M99) if your system installer
has selected this option in AMP.
This section contains the following subsections:
Topic: On page:
Coordinate Offset Using Wheel Position (G92) 11-14
Offsetting Coordinate Zero Points (G52) 11-17
{SET ZERO} Offset 11-18
Jog Offset 11-19
Canceling Coordinate System Offsets (G92.1) 11-20
Canceling Selected Coordinate System Offsets (G92.2) 11-22
Important: All of the offsets described in this section are global in nature.
This means that they apply to all of the work coordinate systems. When
changing work coordinate systems (programming G54-G59), you must
consider the effects of these offsets on the new work coordinate system.
Wheel geometry offsets are not affected by an offset made to the work
coordinate system.
Important: We recommend that wheel length offsets be canceled before
any work coordinate system offsets are executed. If wheel length offsets
are not canceled, the work coordinate system offset is added to the active
wheel length offset. This can cause confusion when changing wheel length
offsets later in the program (see page 13-4 on canceling wheel length
offsets).
