Set in the G84/G88 common tapping (non-rigid tapping), the tapping axis lags behind the
compensation cycle number sampled by spindle encoder. Generally, it is better set it to 4~8.

Note: In the polar coordinate interpolation mode, the more closely the tool is near to the work piece center,
the bigger the speed vector of the rotary axis is. If the center part exceeds the maximum cutting
speed (parameter NO.5462), the servo (NO.411) alarms. Auto feedrate override and auto feedrate
limit function auto controls the feedrate, then, the speed vector of the rotary axis doesn’t exceed the
maximum cutting feedrate.
