Effect of Q parameters
Q60 to Q99 (QS60 to QS99) areal-
ways local.
Q60 to Q99 (QS60 to QS99)
are local or global, depending
on MP7251 in converted cycle
programs (.cyc). Nested calls may
cause problems

Consideration of tool radius
compensation
Behavior with M120 LA1
No effect on processing, as the
control interprets the input internal-
ly as an LA0
Possible undesired effect on
processing, as the control inter-
prets the entry internally as an LA2
Block scan in a point table The tool is positioned above the
next position to be machined
The tool is positioned above
the last position that has been
completely machined
Emtpy CC block (pole adoption from
last tool position) in the NC program
Last positioning block in the
working plane must contain both
coordinates of the working plane
Last positioning block in the
working plane does not necessari-
ly need to contain both coordinates
of the working plane. Can cause
problems with RND or CHF blocks
Axis-specific scaling of RND block RND block is scaled, the result is
an ellipse
Error message is issued
Reaction if a contour element with
length 0 is defined before or after a
RND or CHF block
Error message is issued Error message is issued if a
contour element with length 0 is
located before the RND or CHF
block
Contour element with length 0
is ignored if the contour element
with length 0 is located after the
RND or CHF block
