Spos In Target Block; Travel To Fixed Stop (Fxs) - Siemens SINUMERIK 840D sl Function Manual

Implicit preprocessing stop
Situations in which Interpreter issues an implicit preprocessing stop:
1. In all blocks in which one of the following variable access operations occurs: -Programming
of a system variable beginning with $A...
-Redefined variable with attribute SYNR/SYNRW
2. For the following part program commands:
-Part program command MEACALC, MEASURE
-Programming of SUPA (suppress frames and online offsets)
-Programming of CTABDEF (start of curve table definition)
-Part program command WRITE/DELETE (write/delete file)
-Before the first WRITE/DELETE command in a sequence of such commands
-Part program command EXTCALL
-Part program command GETSELT, GETEXET
-Tool change and active fine tool offset FTOCON
3. For the following command execution:
-Finishing of Type 1 search ("Search without calculation") and
Type 2 search with calculation ("Search at contour end point")
Note: Type 2 search "Block search at contour start point" has the same behavior.

SPOS in target block

SPOS
If a spindle is programmed with M3/M4 and the target block contains an SPOS command, the
spindle is switched over to SPOS on completion of the SERUPRO process (search target
located). This is indicated on the VDI interface.

Travel to fixed stop (FXS)

During repositioning (REPOS), the "Travel to fixed stop" function (FXS) is repeated
automatically. Every axis is taken into account. The torque programmed last before the search
target is used as torque.
System variable
The system variables for "Travel to fixed stop" have the following meaning with SERUPRO:
● $AA_FXS: Progress of the program simulation
● $VA_FXS: Real machine state
The system variables always have the same values outside of the SERUPRO function.
ASUB
A user-specific ASUB can be activated for SERUPRO.
