Offset Tables and Setup
3-19
Enter data in the coordinate system table by using one of four methods:
Method: On page:
Entering work coordinate data manually 3-19
Programming G10 11-8 and 11-11
Setting paramacro system variables 20-16
Entering through the PAL program see the PAL Reference manual or documentation
provided by your system installer
When you use PAL to modify the work coordinate system tables,
dresser/wheel radius compensation (G41 or G42) should not be active. If
dresser/wheel radius compensation is active, be aware that the new offset is
not placed in part program set-up buffers that have already been read into
control memory. This results in the offset not being activated until several
program blocks after the current block. The number of setup buffers
depends on the number of block retrace steps configured in AMP and what
software features are currently being used.
The method described here requires that you key in the data directly to the
table.
To display or change the initial setups for the work coordinate system and
external offset, follow these steps:
1. Press the {OFFSET} softkey on the main menu screen.
