NC_USER_EXTERN_GCODES_TAB [n]:0...59
List of user-specific G commands of an external NC language
min. input limit: -
Normally, ISO Dialect T Code B is implemented for external programming language. Code A
and C are differentiated through the names of the G functions.
The G functions can be renamed with $MN_NC_USER_EXTERN_GCODES_TAB.
G commands for external NC languages can be recoded. The G group and the position
inside the G group are retained. Only G commands can be recoded.
Up to 30 recodings are possible. Example:
$MN_NC_USER_EXTERN_GCODES_TAB[0]="G20"
$MN_NC_USER_EXTERN_GCODES_TAB[1]="G70"
--> G20 is recoded to G70
An error message is displayed during NCK reset if G70 already exists.
EXTERN_FLOATINGPOINT_PROG
Evaluation of programmed values without decimal point
min. input limit: 0
This machine data is effective for external programming languages, i.e. if MD18800
$MN_MM_EXTERN_LANGUAGE = 1.
This machine data is used to define how programmed values without decimal points are
evaluated.
0: Standard notation: Values without decimal points are interpreted in internal units IS-B, IS-
C (see MD EXTERN_INCREMENT_SYSTEM).
Values without decimal point are interpreted in internal units
, e.g. X1000 = 1 mm (at 0.001 mm input resolution)
X1000.0 = 1000 mm
1: PocketCalculator Notation: Values without decimal point are interpreted as mm, inch or
degree.
Values without decimal point are interpreted as mm, inch or degree
, e.g. X1000 = 1000 mm
X1000.0 = 1000 mm
