4.6.4 Backlash Acceleration Function
(1) Overview
If the influence of backlash and friction is large in the machine, a delay
may be produced on reversal of motor, thus resulting in quadrant
protrusion on circular cutting.
This is a backlash acceleration function to improve quadrant
protrusion.
For Series 15-B, 16, 18, 20, and 21, also the two-stage backlash
acceleration function also can be used. (⇒ Subsec. 4.6.5)
Using the servo check board makes it easy to adjust the backlash
acceleration function. (⇒ Sec. 4.19)

−
In semi-closed mode:
Set the machine backlash. (Minimum value = 1)
In full-closed mode:
Set the minimum value of 1. To prevent the backlash
compensation from being reflected in positions, set the
following:
NOTE
Always set a positive value. If a negative value or 0 is
set, the backlash acceleration function is not enabled.
