4. Operation
Self-calibration is performed to guarantee the measurement angle. Performing self-calibration enables
compensation of measurement error due to scale unit and head unit installation. Perform self-calibration
aft er mounting the scale unit and head unit to the rotating stage. Also, perform self-calibration regularly
when a factor arises that may aff ect accuracy, such as a change in ambient temperature.
Th
e calibration value data is saved even if the power is turned off . When the power is turned on and
reference point detection is performed, the saved calibration value data can be automatically read and
applied to compensate the measurement angle.
Note
• Check that the installation and connection work is complete before turning on the power.
Operation Flow
Turn on the power.

Check the LEDs.

Perform reference point detection.

(When reference point detection is performed, the initial or previous calibration value data is read.)
Perform calibration.

4-1. Measurement when Performing Self-calibration
1
Turn on the power
Set the POWER switch on the rear panel of the interpolator unit to ON. Power will be supplied to the
system.
2
Check the LEDs
Check that the POWER, STATUS, CONFIG and SENSOR (1 to 6) LEDs on the front panel of the
interpolator unit light up green.
Note
All the LEDs light up orange immediately aft er the power is turned on. Aft er that, the STATUS LED
turns off before lighting up green.
3
Perform reference point detection
Rotate the rotating stage at a speed of 1 to 10 min
-1
for two full revolutions or more in the clockwise
direction. (See section 9 “Dimensions” for the clockwise direction.)
When the reference point is detected, the MODE LED lights up orange and then changes to lighted up
green.
Note
If the rotating stage is rotated in the counter-clockwise direction (the direction opposite the clockwise
direction), the reference point will not be detected. Be sure to check that the MODE LED changes to
lighted up orange.
Reference
When the reference point detection operation is performed, the initial or previous calibration value
data is read, and that data can be used to output automatically compensated angular data.
