
Y: filter intensity (0 - F)
Indicates average of 2^(Y value). Set to 0 to disable the filter. When the value of Y increases, the
correction is slower which can avoid large amounts of correction during E-Cam adjustment. This
can also avoid disturbances caused by sensor noise for a smoother operation. Setting P2.076.Y
too high causes the alignment to not work properly. The recommended value is 3.
Example:
When the filter intensity is set to 3, the actual filter intensity = 2^3 = 8, which means that after
capturing the error values 8 times, the servo takes the average of the 8 values for the correction
value of the alignment.

Set this bit to 0 to disable this function.
Set this bit to 1 to enable this function. If this function is enabled, the E-Cam
phase alignment is executed when DI.ALGN is on.
The E-Cam displacement value is stored in the PR specified by P2.073.BA.
Set this bit to 1 to trigger this PR command immediately.
Set this bit to 0 and it does not trigger this PR command immediately. Use the PR
command after E-Cam disengages (P5.088.BA) to execute phase alignment.
Set this bit to 0 if the mark is on a non-compensated motion axis, as the position
of the mark is not affected during E-Cam phase alignment.
Set this bit to 1 if the mark is on a compensated motion axis, as the position of the
mark is affected during E-Cam phase alignment.
