ASDA-A3
Differences between positioning with synchronous Capture axis and E-Cam phase
alignment
The synchronous Capture axis and E-Cam phase alignment are both commonly used
compensation approaches for the rotary shear system. In real applications, you can use these
two together. The feature differences of the two are as follows.
Item
Correction method
Digital input (DI)
Marking position
Equal space marking
Random marking
Synchronous Capture axis
Corrects master axis pulses.
High-speed DI7 (CAP) only.
On the non-compensation
motion axis.
Available.
Not available.
E-Cam phase alignment
Uses the PR incremental position command to
correct the slave axis position.
Uses DI.ALGN most of the time. Uses Macro #E
if using high-speed DI7 (CAP) is required.
On any of the axes (compensation or
non-compensation).
Available and can be used with the filter.
When using the high-speed DI7 (CAP) with
Macro #E, using the filter is not suggested.
Keep the distance between the sensor and
cutter within the cutting length per cut.
