B1: Continuous-path mode, Exact stop, Look Ahead

4.9 Supplementary conditions

System variables
The active G0 tolerance factor can be read via the following system variables.
● $AC_STOLF (active G0 tolerance factor)
● $P_STOLF (programmed G0 tolerance factor)
Reset response
After power-on reset, channel reset, or end of part program, the value parameterized in
machine data MD20560 $MC_G0_TOLERANCE_FACTOR becomes effective again.

RESET behavior

MD20150
With the reset (channel or mode group reset), the initial setting parameterized channel-
specifically becomes effective for all G groups:
MD20150 $MC_GCODE_RESET_VALUES (initial setting of the G groups)
The following G function groups are of relevance to "continuous-path mode, exact stop,
LookAhead":
● Group 10: Exact stop - continuous-path mode
● Group 12: Block-change criterion for exact stop
● Group 21: Acceleration profile
● Group 30: NC block compression
● Group 59: Dynamic response mode for path interpolation
For detailed information on setting initial states, see Section "K1: Mode group, channel,
program operation, reset response (Page 455)."

Block change and positioning axes

If path axes are traversed in continuous path mode in a part program, traversing positioning
axes can also simultaneously affect both the response of the path axes and the block change.
A detailed description of the positioning axes can be found in:
