Replaceable Geometry Axes (Geoax) - Siemens SINUMERIK 840D sl Programming Manual

Example 2: AXSTRING
When programming with AXSTRING[SPI(n)], the axis index of the axis, which is assigned to
the spindle, is no longer output as spindle number, but instead the string
Program code
AXSTRING[SPI(2)]
Example 3: MODAXVAL
The modulo position of modulo rotary axis A is to be determined.
Axis position 372.55 is the starting value for the calculation.
The parameterized modulo range is 0 to 360 degrees:
MD30340 MODULO_RANGE_START = 0
MD30330 $MA_MODULO_RANGE = 360
Program code
R10=MODAXVAL(A,372.55)
Example 4: MODAXVAL
If the programmed axis identifier does not refer to a modulo rotary axis, then the value to be
converted (<axis position>) is returned unchanged.
Program code
R11=MODAXVAL(X,372.55)

Replaceable geometry axes (GEOAX)

Function
The "Replaceable geometry axes" function allows the geometry axis grouping configured via
machine data to be modified from the part program. Here any geometry axis can be replaced
by a channel axis defined as a synchronous special axis.
Syntax
GEOAX(<n>,<channel axis>,<n>,<channel axis>,<n>,<channel axis>)
GEOAX()
