Please note while programming:
Machine and TNC must be specially prepared by the
machine tool builder for use of this cycle.
This cycle is effective only for machines with servo-
controlled spindle.
Program a positioning block for the starting point (hole
center) in the working plane with radius compensation R0.
The algebraic sign for the parameter thread depth
determines the working direction.
The TNC calculates the feed rate from the spindle speed.
If the spindle speed override is used during tapping, the
feed rate is automatically adjusted.
The feed-rate override knob is disabled.
If you defined an rpm factor for fast retraction in cycle
parameter Q403, the TNC limits the speed to the maximum
speed of the active gear range.
At the end of the cycle the spindle comes to a stop. Before
the next operation, restart the spindle with M3 (or M4).
Danger of collision!
Enter in MP7441 bit 2 whether the TNC should output an
error message (bit 2=1) or not (bit 2=0) if a positive depth
is entered.
Keep in mind that the TNC reverses the calculation for pre-
positioning when a positive depth is entered. This
means that the tool moves at rapid traverse in the tool axis
to setup clearance below the workpiece surface!

Questions and answers
Can I change the approach direction when cycle def a stud to avoid obstruction to the right
The provided context does not explicitly mention changing the approach direction to avoid obstruction. However, it describes selecting different axis configurations using the MOD function in the Programming and Editing mode. If modifying the axis configuration allows for adjusting the approach direction, it may be possible. Otherwise, specific cycle parameters should be checked in the programming manual.
