⋅Amount of movement per rotation: 360°
⋅ Interval between pitch error compensation positions: 45°
⋅ No. of the compensation position of the reference position: 60
If the above is specified, the No. of the farthest compensation position in
the negative direction for the rotating axis is always equal to the
compensation position No. of the reference position.
The No. of the farthest compensation position in the positive direction is
as follows:
No. of the compensation position of the reference position + (Move
amount per rotation/Interval between the compensation positions)
= 60 + 360/45= 68
The correspondence between the machine coordinate and the
compensation position No. is as follows:

Reference position
Compensation values are output at the positions indicated by .
Therefore, set the parameters as follows:
Parameter Setting value
3620 : Compensation number for the reference position 60
3621 : Smallest compensation position number 60
3622 : Largest compensation position number 68
3623 : Compensation magnification 1
3624 : Interval between pitch error compensation positions 45000
If the sum of the compensation values for positions 61 to 68 is not 0, pitch
error compensation values are accumulated for each rotation, causing
positional deviation.
The same value must be set for compensation positions 60 and 68.
