• BA: PR number (PR#0…PR#99)
After each alignment, any shortage of pulse numbers from the slave axis
is stored in a specified PR. This PR can compensate for the slave position
at the appropriate timing point. If BA is set to 0, any shortage of pulse
numbers is not stored in PR.
•DC: masking range (0…95%)
When the DI.ALGN signal is triggered, the next alignment action is
allowed only after the increasing pulses of the master axis are greater
than the distance (M) masking.
M >= ((ID372) (P5.084) / ID371 (P5.083)) x ID245 (P2.073.DC) %
E-CAM Alignment Control Switch
The settings for ID248 (P2.076)ECamControlConfiguration are described
below.
• X: E-CAM alignment control
The format of this parameter is HEX. Thus, to set PR#11, write 0B to BA.
IMPORTANT
This masking function only works with increasing master pulses, and
does not work for decreasing master pulses.

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.
