B–63610EN/01
156
Example 1) For linear axis
D Machine stroke: –400 mm to + 800 mm
D Interval between the pitch error compensation positions: 50 mm
D No.of the compensation position of the reference position: 40
If the above is specified, the No.of the farthest compensation point in the
negative direction is as follows:
No.of the compensation position of the reference position – (Machine
stroke length in the negative direction/Interval between the
compensation points) + 1
= 40 – 400/50 + 1
=33
No.of the farthest compensation position in the positive direction is as
follows:
No.of the compensation position of the reference position + (Machine
stroke length in the positive direction/Interval between the
compensation positions)
= 40 + 800/50
= 56
The correspondence between the machine coordinate and the
compensation position No.is as follows:
Machine
coordinate (mm)
Compensation
point No.
–400 –350 –100 –50 0 50 100 750 800
33 39 40 41 42 56
Compensation values are output at the positions indicated by f.
Therefore, set the parameters as follows:
Parameter
Setting
No. 3620: Compensation point number for reference position 40
No. 3621: Compensation point number for farthest point in the negative direction 33
No. 3622: Compensation point number for farthest point in the positive direction 56
No. 3623: Compensation magnification 1
No. 3624: Compensation point interval 50000
The compensation value is output at the compensationn position
No.corresponding to each section between the coordinates.
The following is an example of the compensation values.
