WAITS can be used to identify a point at which the NC program waits until one or more spindles
programmed with SPOSA in a previous NC block reach their positions.
Example:
Program code Comment
N10 SPOSA[2]=180 SPOSA[3]=0
...
N40 WAITS(2,3) ; The block waits until spindles 2 and 3 have
reached the positions specified in block N10.
WAITS can be used after M5 to wait until the spindle(s) has (have) stopped. WAITS can be used
after M3/M4 to wait until the spindle(s) has (have) reached the specified speed/direction of
rotation.
Note
If the spindle has not yet been synchronized with synchronization marks, the positive direction
of rotation is taken from the machine data (state on delivery).
Position spindle from rotation (M3/M4)
When M3 or M4 is active, the spindle comes to a standstill at the programmed value.

There is no difference between DC and AC dimensioning. In both cases, rotation continues in
the direction selected by M3/M4 until the absolute end position is reached. With ACN and ACP,
deceleration takes place if necessary, and the appropriate approach direction is taken. With
IC, the spindle rotates additionally to the specified value starting at the current spindle position.
Position a spindle from standstill (M5)
The exact programmed distance is traversed from standstill (M5).
