11. APPLICATION OF FUNCTIONS
1) When the roll feed display is disabled ([Pr. PT26]: _ _ 0 _)
Set the valid range with the distance from the home position.
When the starting position is at 100000, [Pr. PC66] and [Pr. PC67] are set to 500000, and [Pr.
PC68] and [Pr. PC69] are set to 300000, the valid range is between the actual current position of
300000 and 500000 as set in the parameters.

2) When the roll feed display is enabled ([Pr. PT26]: _ _ 1 _)
When the roll feed display is enabled, the valid range is calculated as the starting position is 0.
Set the valid range with the travel distance from the starting position.
When the starting position is at 100000, [Pr. PC66] and [Pr. PC67] are set to 500000, and [Pr.
PC68] and [Pr. PC69] are set to 300000, the valid range is between the feed current position of
300000 and 500000 from the start position (between the actual current position of 400000 and
600000).

Note 1. When TPR1 (Touch probe 1) is assigned to the CN3-6 pin or CN3-19 pin with [Pr. PD24] or [Pr. PD27], a current position data
can be obtained in high speed (within 0.4 ms). When assigning TPR1 to the CN3-6 pin or CN3-19 pin, set the touch probe
input signal filter in [Pr. PD41].
2. The position data is not changed from the previous value.
3. TPR1H (Touch probe 1 rising latch completed) turns off at the same timing as TPR1L (Touch probe 1 falling latch completed)
turns on. Set as TPR1L turns on/off within the range of the latch data.
