Md.800
Number of mark detection counter
The counter value is incremented by 1 at mark detection. Preset "0" clear in
"
Cd.800 Number of mark detection clear request" to execute the mark detection in
specified number of detections mode or ring buffer mode.
Md.801
Mark detection data storage area 1 to 32
The latch data at mark detection is stored. Data for up to 32 times can be stored in
the specified number of detection mode or ring buffer mode.
[4] Precautions
When the data of " Pr.802 Mark detection data type" or " Pr.803 Mark detection data
axis No.
" is selected incorrectly, the incorrect latch data is stored
