Value assignments
The angle of the sum vector is calculated from 2
vectors standing vertically one on another. The 2nd
vector specified is always used for angle reference.
Result in the range: –180 to +180 degrees
Used instead of M2 – to maintain the continuous-path
control mode
0.001 ... 99 999.999 Dwell time in spindle revolutions
1 ... 32 000 The tool change can be performed either directly using
only integer, without sign the T command or only with M6. This can be set in the
machine data.

Positional 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; specified as a
percentage
– It is also possible to specify the dimensions for the end
point of a rotary axis with ACP(...) irrespective of
G90/G91.
– It is also possible to specify the dimensions for the end
point of a rotary axis with ACP(...) irrespective of
G90/G91.
0.00001 ... 359.99999
Specified in degrees;
one possibility of specifying a straight line when using
G0 or G1 if only one end-point coordinate of the plane
is known or
if the complete end point is known with contour ranging
over several blocks
