20550 EXACT_POS_MODE
- Exact stop conditions on G00/G01.
-
- -
Configuration of the exact stop conditions for G00 and other G codes of the
Description:
1st G code group.
The MD is decimal-coded. The units digits define the behavior at G00 (infeed
motion) and the tens digits the behavior of all the other G codes of the 1st
group ("machining G codes").

become active.
1x:
independent of the programmed exact stop condition.
2x:
active independent of the programmed exact stop condition.
3x:
independent of the programmed exact stop condition.
The values of the units digits and tens digits are added.
For example, the value of EXACT_POS_MODE = 2 means that the exact stop condi-
tion G602 is always activated automatically at G00, independently of which
exact stop condition was programmed. At all other G codes of group 1, the
programmed exact stop condition becomes active.
20552 EXACT_POS_MODE_G0_TO_G1
- Exact stop condition at G00-G01 transition
-
- -
Configuration of a stop at transition from G00 to a different G code of the
Description:
1st G code group, and also vice versa, at transition from non-G00 to G00 in
continuous-path mode.
In exact-stop mode, the positioning window programmed or set in MD20550
$MC_EXACT_POS_MODE is used.

in addition, the override of the subsequent non-G00 block is taken into
account in the G00 block via LookAhead in the case of a change from G00 to
non-G00.

in addition, the override of the subsequent block is taken into account via
LookAhead in the case of a change from G00 to non-G00 and non-G00 to G00.
