EXTERN_INCREMENT_SYSTEM
Increment system
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 which increment system is active:
0: Increment system
IS-B= 0.001 mm/degree
= 0.0001 inch
1: Increment system
IS-B= 0.0001 mm/degree
= 0.00001 inch
EXTERN_DIGITS_TOOL_NO
Number of digits for T number in the external language mode
min. input limit: 2
The machine data is active only in $MN_EXTERN_CNC_SYSTEM = 2.
Number of digits in tool number in the programmed T value.
The number of leading digits specified as tool number is interpreted with
$MN_EXTERN_DIGITS_TOOL_NO from the programmed T value. The following positions
address the offset memory.
MM_EXTERN_LANGUAGE
External language is active in the control system
min. input limit: 0
To process part programs of other system manufacturers, one must activate the
corresponding NC language. Only one external language is to be selected. The already
defined relevant instruction set can be taken from the current documentation.
Bit 0 (LSB): Processing of part programs ISO_2 or ISO_3. For encoding, see
