6. APPLICATION FUNCTIONS
(3) Latch data range
When data at mark detection is within the latch data range, the data is stored in the mark detection storage
device and the mark detection counter increases by one. When the data is outside of the range the mark
detection is not processed. The following explains the upper limit value and lower limit value.
(a) Upper limit value > lower limit value
When the mark detection data is more than the lower limit value and also less than or equal to the upper
limit value, the mark detection is processed.
Lower limit value Upper limit value
(b) Upper limit value < lower limit value
When the mark detection data is less than the upper limit value or more than the lower limit value, the
mark detection is processed.
Upper limit value Lower limit value
(c) Upper limit value = lower limit value
The range of the mark detection data is not checked. Mark detection is processed for all ranges.
(4) Mark detection clear command
When a mark detection clear command is input the mark detection counter becomes 0, and mark detection
edge data and mark detection positioning data is cleared.
