This parameter specifies for drilling and tapping tools during
cycle programming whether switching commands are
generated for the spindle or the driven tool.
0: Stationary tool
1: Driven tool
NL: Usable length
RW: Position angle – Deviation from the main machining
direction (range: –90° to +90°)
AX: Salient length in X
FH: Height of the chuck for driven tool
FD: Diameter of the chuck
