No. of the compensation position of the reference position + (Machine
stroke on the positive side/Interval between the compensation
positions)= 40 + 800/50= 56
The correspondence between the machine coordinate and the
compensation position No. is as follows:

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 40
3621 : Smallest compensation position number 33
3622 : Largest compensation position number 56
3623 : Compensation magnification 1
3624 : Interval between pitch error compensation positions 50000
The compensation amount is output at the compensation position No.
corresponding to each section between the coordinates.
The following is an example of the compensation amounts.

Reference
position
- For rotary axis
- 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.
