Value assign- Information
ments
The angle of the sum vector is
calculated from 2 vectors stand-
ing vertically one on another.
The 2nd vector specified is al-
ways used for angle reference.
Result in the range: -180 to +180
degrees
Used instead of M2 - to maintain
the continuous-path mode
0.001 ... 99 Unit of measurement of the

sign command or only with M6. This
can be set in the machine data.

- The dimension can be specified
for the end or center point of a
certain axis, irrespective of G91.
1 ... 200, integer Acceleration override for an axis
or spindle; specified as a per-
centage
- It is also possible to specify the
dimensions for the end point of a
rotary axis with ACP(...) irrespec-
tive of G90/G91; also applies to
spindle positioning
