Application
Indirectly programming position attributes is used in replacement cycles, as in this case, the
following advantage exists over programming position attributes as keyword (e.g. IC, AC, ...):
As a result of the indirect programming as variable, no CASE statement is required, which
would otherwise branch over all possible position attributes.
Syntax
<POSITIONING COMMAND>[<axis/spindle>]=
GP(<position>,<position attribute)
<axis/spindle>=BP(<position>,<position attribute)
Meaning
<POSITIONING COMMAND>[]:
<axis/spindle>:
GP():
<position>:
<position attribute>:
The values supplied from the variables have the following significance:

The following positioning commands can be programmed to‐
gether with the key word GP:
POS, POSA,SPOS, SPOSA
Also possible:
● All axis and spindle identifiers present in the channel:
<axis/spindle>
● Variable axis/spindle identifier AX
Axis/spindle that is to be positioned
Key word for positioning
Parameter 1
Axis/spindle position as constant or variable
Parameter 2
Position attribute (e.g. position approach mode) as a variable
(e.g. $P_SUB_SPOSMODE) or as key word (IC, AC, ...)
Permissible for:
POS, POSA,SPOS, SPOSA,AX, axis address
POS, POSA,SPOS, SPOSA,AX, axis address
POS, POSA,SPOS, SPOSA,AX, axis address
POS, POSA,SPOS, SPOSA,AX, axis address
POS, POSA,SPOS, SPOSA,AX, axis address
