Example 3: Take the X axis as an example, the pitch error compensation origin point is 127, the
compensation interval is 10000.
Note: The data in “( )” is the measured result is incremental value, i.e. positive error indicates excessive
movement, and negative error indicates insufficient movement.
Compensation point 127 corresponds to the reference point; compensation point 126
corresponds to the position -10000 μ m; hereafter, a compensation point is made at regular interval
(every -1000 μ m); A compensation value is set at the compensation point 127 when the tool moves
within the range -10000~0 μ m; A compensation value is set at the compensation point 126 when the
tool moves within the range -20000~-10000 μ m; The compensation value at compensation point n is
set when the tool moves within the range: （ n － 128 ） × （ compensation interval ） to (n-127) ×
（
compensation interval
）
.
According to the measured result in above, the parameters are set as follows:
— Set the parameter No. 24 to ×1
— Set the parameter No. 39 to 127
— Set the parameter No. 163 to 10000
