1.2.6 Programmable scaling factor: SCALE, ASCALE
Functionality
A scale factor can be programmed for all axes with SCALE, ASCALE. The path is enlarged
or reduced by this factor in the axis specified.
The currently set coordinate system is used as the reference for the scale change.
Programming
SCALE X... Z... ; Programmable scaling factor, clears old instructions for offset,
rotation, scaling factor, mirroring
ASCALE X... Z... ; Programmable scaling factor, additive to existing instructions
SCALE ; Without values: clears old instructions for offset, rotation, scaling
factor, mirroring
The instructions that contain SCALE or ASCALE each require a separate block.
Notes
● For circles, the same factor should be used in both axes.
● If an ATRANS is programmed with SCALE/ASCALE active, these offset values are also
scaled.
