8.4 Positioning spindles (SPOS, SPOSA, M19, M70, WAITS)
Set spindle to specified angle
SPOS and SPOSA have the same functionality but differ in their block change be‐
havior:
● SPOS delays the enabling of the NC block until the position has been reached.
● SPOSA enables the NC block even if the position has not been reached.
Number of the spindle to be positioned.
<n>:
If a spindle number is not specified or if the spindle number is set
to "0", SPOS or SPOSA will be applied to the master spindle.
Angular position to which the spindle is to be set.

Type:
The following options are available for programming the position
approach mode:
=AC(<value>):
=IC(<value>):
=DC(<value>):
=ACN(<value>):
=ACP(<value>):
=<value>:
Set the master spindle (M19 or M0=19) or spindle number <n> (M<n>=19) to the
angular position preset with SD43240 $SA_M19_SPOS with the position approach
mode preset in SD43250 $SA_M19_SPOSMODE.
The NC block is not enabled until the position has been reached.
Switch the master spindle (M70 or M0=70) or spindle number <n> (M<n>=70) over
to axis mode.
No defined position is approached. The NC block is enabled after the switchover
has been performed.
Motion end when "Exact stop fine" reached
Motion end when "Exact stop coarse" reached
End of motion on reaching "interpolator stop"
Spindle for which the programmed end-of-motion criterion is to be effective
Spindle number
<n>:
If a spindle is not specified in [S<n>] or a spindle number of "0" is specified, the
programmed end-of-motion criterion will be applied to the master spindle.
