7.4 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 behavior:
• 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.
