E-Cam alignment control

Filter intensity (0 - F)

X: E-Cam alignment control

Y: filter intensity (0 - F)

Indicates average of 2^(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.

When the filter intensity is set to 3, the actual filter intensity = 2^3 = 8, which means that after

capturing 8 times of error values, the 8 values are averaged for the correction value of the

UZ: alignment forward direction allowable rate (0 - 100%)

Set this bit to 0 to disable this function.

Set this bit to 1 to enable this function. If enabled, the E-Cam phase alignment

is executed when DI.ALGN is on.

The E-Cam displacement value is stored in the PR data location 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 (P5.088.BA) when E-Cam disengages 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 when aligning.

Set this bit to 1 if the mark is on a compensated motion axis, as the position of

the mark is affected when aligning.
