3623 Magnification for pitch error compensation for each axis
Data type: Byte axis
Unit of data: 1
Valid data range: 0 to 100
Set the magnification for pitch error compensation for each axis.
If the magnification is set to 1, the same unit as the detection unit is
used for the compensation data.

Input in inches 0.0001 inch
Valid data range: 0 to 99999999
The pitch error compensation points are arranged with equally
spaced. Set the space between two adjacent points for each axis.
The minimum interval between pitch error compensation points is
limited and obtained from the following equation:
Minimum interval of pitch error compensation points = maximum
feedrate (rapid traverse rate)/7500
Unit: mm, inches, deg, or mm/min, inches/min, deg/min
[Example]
When the maximum rapid traverse rate is 15000 mm/min, the
minimum interval between pitch error compensation points is 2 mm.
Examples of parameters
D Machine stroke: –400 mm to +800 mm
D Interval between the pitch error compensation points: 50 mm
D No. of the compensation point 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 point 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 point in the positive direction is as
follows:
No. of the compensation point of the reference position +
(Machine stroke length in the positive direction/Interval between
the compensation points)
= 40 + 800/50
= 56
