LH71/LH72 Segmented error compensation Setting manual
Create compensation data for the changing points narrowed down to 32 points or less from the error curve measured
in
step 1.
* Since the reference point position is 0, it is not included in the compensation points.

Error curve compensation data for the above 5 changing points
(Unit: mm)
Changing point:
- Point where the slope of the error curve changes
- Point where the inclination is reversed
Number of points that can be input:
up to 32 points
Compensation amount:
up to
±
600μm
Number the changing point in order from the smallest (or minus) side of the count value of the measurement unit.

STEP 2
Reference point position: 0
Number the changing point in order from the smallest (or minus) side of the count value of the measurement unit. If the start position of
the segmented error compensation is position 1 and the end position is position N, the position N should be 32 or less.
The maximum compensation value for the entire changing point is within
±
600μm. If it exceeds the
±
600μm range, the segmented
error compensation function cannot be used.
NOTE:
- The segmented error compensation function is applied to the range from the start position (ε 1) to the end position (ε n).
- Input compensation data cannot be handled below the unit of input resolution of the measurement unit.
