Minimum input limit: 0
Protection level: 2/7
This machine data is effective for external programming languages, i.e. if
MD 18800: MM_EXTERN_LANGUAGE = 1.
This machine data defines which increment system is active
0: Increment system IS- -B= 0.001 mm/degree
= 0.0001 inch
1: Increment system IS- -C = 0.0001 mm/degree
= 0.00001 inch
EXTERN_DIGITS_TOOL_NO

Minimum input limit: 2
Protection level: 2/7
The machine data is only effective with $MN_EXTERN_CNC_SYSTEM = 2. Number of
digits for tool number in programmed T value.
The number of leading digits specified in $MN_EXTERN_DIGITS_TOOL_NO is interpreted
as the tool number from the programmed T value. The trailing digits address the compensa-
