0.0 means that the IPO buffer control, for a full IPO buffer stops limiting the path
feedrate. This shortens the machining time, but it can increase the risk of the IPO
buffer running empty.
1.0 means that the IPO buffer control, with full IPO buffer continues to control the
path feedrate, and
therefore avoids the IPO buffer becoming empty faster. This results
in minor fluctuations of the IPO buffer fill level. However, a longer machining time
must be expected.
Values between 0.0 and 1.0 permit a smooth, seamless transition from the old to the
new response.

Description: This machine data defines the behaviour of the programmable function CPRECON.
0: The CPRECON function is inactive when feedforward control is activated
simultaneously.
1: CPRECON is also active with feedforward control.
2: As 1, but the function is parameterised with MD32415 $MA_EQUIV_CPREC_TIME.
3: As 2, but any contour accuracy programmed with CTOL has priority over SD42450
$SC_CONTPREC.
4: CPRECON is active independently of the feedforward control and jerk filter. Only
MD32415 $MA_EQUIV_CPREC_TIME is taken into account in the calculation of the contour
error.
All time
constants that have effects on the contour error must be summated and
entered MD32415 $MA_EQUIV_CPREC_TIME.
5: As 4, but a contour accuracy that may have been programmed with CTOL has priority
over SD42450 $SC_CONTPREC.
The values 0 and 1 are no longer recommended. They only provide compatibility with
older software versions.

Description: Configuration of smoothing with G641 and G642 or G643.
The MD is decimal-coded. The units digits define the response with G643, and the tens
digits the response with G642. The hundreds digit can define whether, with G641 or
G642,
the axes
may be accelerated within the smoothing range or traversed at constant
velocity. The thousands and ten-thousands digits are used to configure smoothing with
G644.
x0: G643 uses axis-specific tolerances; these are set with the axis-specific MD33100
$MA_COMPRESS_POS_TOL.
