In the standard setting, a transition element is inserted for positioning with
rotary axes at non-tangential transitions (depending on the acceleration, jerk
and tolerance). With M134, an exact stop is made at these transitions:

1: Function is effective
Bit 5 – Reserved
Bit 6 – Automatic activation of M134
0: M134 must be activated in the NC program
1: M134 is automatically activated when an NC program is
selected
Before execution of a fixed cycle, the spindle must be started with M3 or M4.
If this is not the case, the error message Spindle ? appears. If you are using
a high speed cutting (HSC) spindle that is started by its own M function (not
M3 or M4):
7 7 7 7
Suppress the error message Spindle ? with MP7441 bit 0.
If a positive depth is programmed in machining cycles, the error message
Enter depth as negative appears:
7 7 7 7
Suppress the error message Enter depth as negative with MP7441 bit 2.
