If a value other than the above is set, the warning "Outside mark detection data
axis No. setting range" (warning code: 132) occurs and the target mark detection
is not available.
[Pr.804] Mark detection data buffer memory No.
Set the No. of optional 2 words buffer memory that latched at mark detection.
Set this No. as an even No.
If a value other than the above is set, the warning "Outside mark detection data
buffer memory No. setting range" (warning code: 133) occurs and the target mark
detection is not available.
