SEQUENCE
The programmable rotation ROT, AROT can be used:
The rotation is performed in the current plane G17, G18 or G19 using the value of
RPL=...specified in degrees.
A scale factor can be programmed for all axes with SCALE, ASCALE. The path is
enlarged or reduced by this factor in the specified axis. The currently set coordinate
system is used as the reference for the scale change.
SCALE X...Y... Z... ; programmable rotation offset (absolute)
ASCALE X...Y... Z... ; programmable offset, additive to existing offset
(incremental)
If a program contains SCALE or ASCALE, this must be programmed in a separate block.
ROT RPL=...
; programmable rotation offset (absolute).
AROT RPL=…
; programmable offset, additive to existing offset (incremental)
ROT
; without values, clears old commands for offset
