System variables
The spindle-specific auxilary functions are always stored in the following system variables on
block search, irrespective of the programming described above:
System variable Description
$P_SEARCH_S[n] Collected spindle speed,
value range = { 0 ... Smax }
$P_SEARCH_SDIR[n] Collected spindle rotation direction,
value range = { 3, 4, 5, -5, -19, 70 }
$P_SEARCH_SGEAR[n] Collected spindle gear stage M function,
value range = { 40 ... 45 }
$P_SEARCH_SPOS[n] Collected spindle position,
value range = { 0 ... MD30330 $MA_MODULO_RANGE }
Collected traverse path,
value range = { -100.000.000 ... 100.000.000 }
$P_SEARCH_SPOSMODE[n] Collected position approach mode,
value range = { 0 ... 5 }
For later output of the spindle-specific auxiliary functions, the system variables can be read,
for example in an ASUB, and output after output of the action blocks:
DB21, ... DBX32.6 == 1 (last action block active)
Note
The contents of the system variables $P_S, $P_DIR and $P_SGEAR may be lost after block
search due to synchronization operations.
