The compensation is not executed when the input compensation backlash is zero.
⑥ After the pitch error parameter is set, the CNC is turned on again, and the pitch error
parameter is enabled after the machine zero return is executed.
z The following is the compensation parameters, taking X axis as example:
Parameter Setting value
NO.216
：
compensation number of X-axis reference point 0
NO.221
： X-axis pitch error compensation points 128
NO.226
：
X-axis pitch error compensation backlash 10
NO.231
：
X-axis pitch error compensation override 0.001
The error compensation takes the machine zero as reference pont. The pitch error
compensation is executed when the positive coordinate system of machine zero is moving.

The displayed compensation points during compensation list take the set compensation points as
the reference, corresponding to the reference point(pitch error origduring 0), the compensation
point 1 corresponds to the position which is 10.000 from the reference point, the increment of
10.000 after it is taken as one compensation point, and the compensation value of No.127
compensation point is at 1270.000. So, at the compensation parameter number 0 during

, set the comensaption value from 0 to 10.000, and set the compensation
value from 10.000 to 20.000 at the comepsnation point 1. For the compensation point N, the CNC
sets the compensation value from N×(compensation backlash) to (N

backlash).
Actually, when the machine moves to +30.000 from the reference point, the compensation value of
pitch error is:
(+7)+(-6)+(+4)=+5
