Spindle positioning (SPOS, SPOSA, M19, M70, WAITS): Further information

Further information
Positioning with SPOSA
The block step enabling or program execution is not affected by SPOSA. The spindle positioning can be performed during
execution of subsequent NC blocks. The program moves onto the next block if all the functions (except for spindle)
programmed in the current block have reached their block end criterion. The spindle positioning operation may be
programmed over several blocks (see WAITS).
Note
If a command, which implicitly causes a preprocessing stop, is read in a following block, execution of this block is delayed
until the positioning spindle is stationary.
Positioning with SPOS/M19
The block step enabling condition is met when all functions programmed in the block reach their end-of-block criterion (e.g.
all auxiliary functions acknowledged by the PLC, all axes at their end point) and the spindle reaches the programmed
position.
90
Switch on cross drilling attachment.
Set main spindle to 0° immediately,
the program will advance to the next block straight away.
Switch on the drill while the spindle is taking up position.
Wait for the main spindle to reach its position.
Feedrate in mm/min (G96 is suitable only for the multi-edge turn-
ing tool and synchronous spindle, but not for power tools on the
cross slide.)
The spindle is positioned through 90° with read halt in a positive
direction.
The spindle is positioned at 180° relative to the spindle zero
point.
The spindle turns in a positive direction through 90° from the
absolute 180° position, ending up in the absolute 270° position.
