Characters and character sequences which have a defined meaning
in the programming language
for --> part programs (see Programming Guide).
Three--dimensional area within a --> working area which the tool tip
is not permitted to enter (programmable via MD).
Contour errors on quadrant transitions caused by frictional
fluctuations on guideways can be largely eliminated by means of
quadrant error compensation. A circularity test is performed to
parameterize the quadrant error compensation function.
Calculation parameter. The programmer can assign or request the
values of the R parameter in the --> part program as required.
This rail is used to mount the modules of the S7--300 system.
The highest traversing speed of an axis used, for example, to bring
the tool from an idle position to the --> workpiece
contour or retract it from the workpiece contour.
Point on the machine tool with which the measuring system of the
--> machine axes is referenced.
If the position measuring system used is not an absolute--value
encoder, then a reference point approach operation is required to
ensure that the actual values supplied by the measuring system are
in accordance with the machine coordinate values.
