Siemens SINUMERIK 808D ADVANCED Parameter Manual

Value 0: Default LookAhead
Value 1: Extended LookAhead
Value 2: reserved
E.g. MD20443 $MC_LOOKAH_FFORM[4]=1; i.e. activation for DYNFINISH.
Entry for all dynamic G code groups.
When changing between default LookAhead and extended LookAhead or vice versa, the
continuous-path mode is interrupted by an interpolatory stop.

Description: The MD defines how significantly the IPO buffer control (FIFOCTRL) should influence
the path feedrate with the buffer full.
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 behavior 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 parameterized with MD32415 $MA_EQUIV_CPREC_TIME.
3: As 2, but any contour accuracy 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.
