The address extension [<n>] with <n>=spindle number may not apply for the main spindle.
SPOS[<n>]=AC(...)
Spindle positioning to an absolute position (0 to 359.999 degrees). The positioning direction is determined either
by the current direction of spindle rotation (spindle rotating) or the distancetogo.
SPOS[<n>]=IC(...)
Spindle positioning to an incremental position (+/- 999999.99 degrees) in relation to the last programmed
position. The positioning direction is defined by the sign of the path to be traversed.
SPOS[<n>]=DC(...)
Spindle positioning across the shortest path to an absolute position (0 to 359.999 degrees).
The positioning direction is determined either by the current direction of spindle rotation (spindle rotating) or
automatically by the control (spindle stationary).
SPOS[<n>]=...
Same functional sequence as SPOS [<n>]=DC(...).
SPOS[<n>]=ACP(...)
Approaches the position from the positive direction.
When positioning from a negative direction of rotation, the speed is decelerated to zero and accelerated in the
opposite direction to execute the positive approach.
SPOS[<n>]=ACN(...)
Approaches the position from the negative direction.
