CHAPTER 6 SCREW-PITCH COMPENSATION
6.1 Screw-Pitch Compensation
0 0 0 3 *** ***
PCOMP
*** *** *** D/R ***
PCOMP =1: Screw-pitch error compensation valid;
=0: Screw-pitch error compensation invalid.
6.2 Screw-Pitch Error Origin
A position No. which the screw-pitch error compensation starts from in the compensation list, which is
determined from the machine zero, is called screw-pitch error compensation origin (compensation original
point). Each axis may be set in any position from 0 to 1023, which is set by data parameter
№ 3620
depending on the mechanical requirement.
3 6 2 1 Min. position number of each axis for pitch error compensation
3 6 2 2 Max. position number of each axis for pitch error compensation
3 6 2 0 Screw-pitch error compensation position number of each axis machine zero
6.3 Offset Interval
3 6 2 4 Interval of each axis screw-pitch error compensation
Setting range
：
1000
～
999999 (Unit:0.001mm)
6.4 Compensation Value
The axes screw-pitch offset values are set in the page of screw-pitch parameter. Refer to the following
table. Input range: -2550~2550.The offset value is input by diameter with the unit 0.001mm. （ Take X, Y, Z
axes as example
）
Offset No. X Y Z

6.5 Cautions for Offset Setting
① The setting and modification of screw-pitch offset can only be done at the authority of password level
2 and switch on parameter switch.
②
Offset is not allowed if the offset interval entered is 0
③ After the parameter of screw-pitch offset is set, only the machine zero is returned could the
compensation be done.
