9.9 Mark Detection Function
[Pr.800] Mark detection signal setting
Set the input signal for mark detection.
If a value other than the above is set, the warning "Outside mark detection signal setting range" (warning code: 0936H) occurs
and the target mark detection is not available.
Set "4: High speed input request" in "[Pr.42] External command function selection" and set "1: Validates an external
command." in "[Cd.8] External command valid".
[Pr.801] Mark detection signal compensation time
Compensate the input timing of the mark detection signal.
Set this parameter to compensate such as delay of sensor input. (Set a positive value to compensate for a delay.)
[Pr.802] Mark detection data type
Set the data that latched at mark detection.
The target data is latched by setting "0 to 12". Set the axis No. in "[Pr.803] Mark detection data axis No.".
Optional 2 word buffer memory is latched by setting "-1". Set the buffer memory No. in "[Pr.804] Mark detection data buffer
memory No.".
If a value other than the above is set, the warning "Outside mark detection data type setting range" (warning code: 0937H)
occurs and the target mark detection is not available.
