Pitch error compensation of rotary axis
When the additional axis is linear or rotary (B type), the pitch error compensation mode is the
same as the linear axis. The following example explains the pitch error compensation function when
the additional axis is taken as the rotary axis (A type).
No. 1260 (movement amount of rotary per rev) = 360
，
№ 3624
（
pitch error compensation interval
）
= 45
№ 3620 （ pitch error compensation number corresponded to machine zero ） = 60
Set the minimum pitch error compensation position number No. 3621 of the rotary axis=50, the maximum
pitch error compensation position number No. 3622=100
After the above parameters are set, the farthest pitch error compensation position number of the rotary axis
in the negative direction is equal to compensation position number of reference point.
The farthest compensation position number in the positive direction is:
Compensation position number of reference point+ （ movement amount per rev/compensation
position interval
）
= 60+360/45 = 68
Relations between machine coordinates and compensation position number:
When compensation sum of the position 60
～
68 is not 0, a position error occurs. The sum is an
accumulation of pitch error compensation value per rev. the same compensation values must be set at the
position 60 and 68 as follows:
Compensation

60 61 62 63 64 65 66 67 68
Set compensation
