15.13 SMOOTH BACKLASH COMPENSATION
In ordinary backlash compensation, all backlash compensation pulses
are output when the direction of axis movement is reversed (Fig.
5.13(a)).

Fig. 5.13(a) Ordinary Backlash Compensation
In smooth backlash compensation, the backlash compensation pulses
corresponding to a distance traveled from the point of direction
reversion are output. So, fine backlash compensation taking advantage
of machine properties is enabled (Fig. Fig. 5.13(b)).
