Motion Control Applications
• 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 ID248 (P2.076) too high causes the alignment to not
work properly. The recommended value is 3.
Example: when the filter intensity value is 3, the actual filter intensity =
2^3 = 8.
• UZ: alignment forward direction allowable rate (0…100%)
X E-Cam alignment control UZ Alignment forward direction
allowable rate (0…100%)
Y Filter intensity (0 - F) - -
Bit Function Description
0 Enable alignment Set this bit to 0 to disable this function; set this bit to 1 to enable this function.
If enabled, the E-Cam alignment correction is executed when DI.ALGN is on.
1 Trigger PR immediately Set this bit to 1 to enable this function. When the E-Cam alignment is executing, the
correction is stored in the PR data location specified by ID245 (P2.073), which triggers the
PR immediately.
Set this bit to 0 to disable this function. When the E-Cam alignment is executing, it does not
trigger PR immediately to compensate the correction. You must use the PR ID376
(P5.088.BA) when E-Cam disengages in order to execute it.
2 Position of the mark 0: if the mark is on the master axis, the position of the mark is not affected when aligning.
1: if the mark is on the slave axis, the position of the mark is affected when aligning.
