When the touch probe function (60B8h) is set, and TPR1 (touch probe1), an external signal, is turned
on/off, the current position of the rising and falling edges are latched.
The latch status of the current position data can be checked with the touch probe status (60B9h). The
latched current data can be read with the touch probe position positive value (60BAh) and the touch
probe position negative value (60BBh). For details of each object, refer to sections 6.4.9 to 6.4.12.
(2) Usage
The following explains for latching the current position at the rising edge of TPR1 (Touch probe 1).
(a) Set "0013h" to the touch probe function setting (Touch probe function: 60B8h) to store data at rising
edge of TPR1 (Touch probe 1).
(b) At this time, the touch probe status (Touch probe status: 60B9h) is set to "0001h", and the latched
data has not been stored yet.
(c) Use an external signal to turn on TPR1 (Touch probe 1).
(d) The touch probe status (Touch probe status: 60B9h) changes to "0003h", and the current position at
the time of TPR1 (touch probe1) on will be stored to the rising edge position of touch probe (Touch
probe position positive value: 60BAh).
(e) Use an external signal to turn off TPR1 (Touch probe 1).
(f) The touch probe status (Touch probe status: 60B9h) remains "0003h", and the current position at
the time that TPR1 (Touch probe 1) turns off will not be stored as the touch probe falling edge
position (Touch probe position negative value: 60BBh).
(g) Latching can be continued from (c).
