Item Specifi cation Notes
Circular run-out
of scale relative to
rotational axis When using a mechanical
reference to check the
scale unit inner diameter
part 0.010 mm Install using the reference surface of
the scale unit inner diameter part as
the reference, or use a microscope
and install using the lines recorded
on the scale surface as the reference.
See section 3-1-3 “Example of
Installation Procedure” for details
of the lines recorded on the scale
surface.
When using a microscope
and checking with the
line references recorded
on the scale surface 0.020 mm
Total run-out of scale mounting surface 0.010 mm Including installation tolerance
and fl uctuation during rotational
movement.
Circular run-out of head unit mounting surface 0.050 mm Including installation tolerance
and fl uctuation during rotational
movement. See section 9
“Dimensions” for details.
Co-axiality of head
unit relative to
scale unit Head unit inner diameter
reference

0.040 mm
Installation using the supplied axis
alignment jig is possible. See section
9 “Dimensions” for the reference
surface and other details.
Head unit outer diameter
reference

0.020 mm
Installation using an external
reference is possible. See section
9 “Dimensions” for the reference
surface and other details.
Distance between scale and head reference
surfaces 1.503 ±0.020 mm Including installation tolerance
and fl uctuation during rotational
movement.
Axial run-out of stage Less than 0.010 mm
Rotational accuracy during self-calibration 1 to 10 min
-1
Calibration may not be possible if the
rotational accuracy during
self-calibration is low.
Tightening torque
during installation Head unit (M6) 1.0 ±0.1 N·m Control with a torque wrench.
Uneven or excessive tightening
torque may reduce the accuracy or
cause damage.
Scale unit (M4) 0.6 ±0.06 N·m
8-3. Calibration Conditions
Th e calibration conditions of the issued calibration certifi cate are shown below.
Item Condition Notes
Temperature 20 ±1°C
Number of angle points 1,048,576
Measured signals A, B and Z signals Th e rising edge of the A signal is set as
the angle point. Angle point No. 1 is set
at the rising edge of the fi rst A signal aft er
detection of the Z signal (reference signal).
Rotation conditions CW, CCW
5 min
-1
Mounting position Standard mounting position
described in section 9 “Dimensions” Angle deviation and uncertainty are
calculated through measurement of a total
of 16 installation status patterns consisting
of four diff erent scale unit and head unit
positions each shift ed by 90° symmetric to
the rotational axis.
