26.2.2.2 Setting Compensation Amount of Backlash Compensation II
For the backlash compensation II compensation amount, set the size of projection which is generated at axis direction
reversal.
For the unit of compensation amount, follow the setting of "#1006 mcmpunit" (Machine error compensation unit).
 Backlash compensation II compensation amount 1: "#14362 BL2_c1"
 Backlash compensation II compensation amount 2: "#14364 BL2_c2"
 Backlash compensation II compensation amount 3: "#14366 BL2_c3"
 Backlash compensation II compensation amount 4: "#14368 BL2_c4"
Set compensation amounts corresponding to acceleration rates which have been set in the previous chapter "26.2.2.1 Setting
the Backlash Compensation II Acceleration Rate" for the parameters above.
For example, set a compensation amount which corresponds to backlash compensation II acceleration rate 2 for "#14364
BL2_c2".
When a positive value is set as the compensation amount, compensation is performed in the travel direction of the axis after
axis reversal.
[Compensation direction with a compensation amount set to a positive value]
When a negative value is set as a compensation amount, compensation is performed in the travel direction of the axis before
axis reversal.
[Compensation direction with a compensation amount set to a negative value]
