Detailed Description
2.1 Spindle modes
Basic logic functions: Spindles (S1)
16 Function Manual, 11/2006, 6FC5397-0BP10-2BA0
SD43240 and SD43250
The positioning data for M19 are stored in the following axis specific setting data:
SD43240 $SA_M19_SPOS[n] (Position)
and
SD43250 $SA_M19_SPOSMODE[n] (Position approach mode)
.
End of positioning
The end of the positioning motion can be programmed using the following commands:
FINEA [Sn]
End of motion on reaching "Exact stop fine" (DB31, ... DBX60.7)
COARSEA [Sn]
End of motion on reaching "Exact stop coarse" (DB31, ... DBX60.6)
IPOENDA [Sn]
End of motion when “IPO stop” is reached
Block change
Settable block change time
In addition to the existing programmable endofmotion criterion with FINEA, COARSEA,
IPOENDA, for singleaxis interpolation, a new endofmotion criterion can be programmed for
block change with IPOBRKA in the braking ramp (100-0%).
The program advances to the next block if the end-of-motion criteria for all spindles or axes
programmed in the current block, plus the block change criterion for path interpolation, are
fulfilled. This applies to both part-program and technology-cycle blocks.
Further explanations regarding configurable set change time of "configurable positioning
axes" for single axis interpolation can be found under:

SPOS, M19 and SPOSA have the same functionality, but differ in their block change behavior:
• Programming with SPOS and M19
The block change is carried out if all functions programmed in the block have reached
their endofblock criterion (e.g., all auxiliary functions acknowledged by the PLC, all axes
have reached their end points) and the spindle has completed its positioning motion.
• Programming with SPOSA
The program moves to the next block if all the functions (except for spindle) programmed
in the current block have reached their end-of-block criterion. If SPOSA is the only entry in
the block, block change is performed immediately. The spindle positioning operation may
be programmed over several blocks (see WAITS).
