Usage
The following explains for latching the current position at the rising edge of TPR1 (Touch probe 1).
1.
Set "0013h" to the touch probe function (60B8h) to store data at the rising edge of TPR1 (Touch probe 1). (a)
2.
At this time, Touch probe status (60B9h) is "0001h", and the latched data has not been stored yet. (b)
3.
Use an external signal to turn on TPR1 (Touch probe 1). (c)
4.
Touch probe status (60B9h) changes to "0003h", and the current position at the time TPR1 (Touch probe 1) turns on is
stored as the Touch probe position positive value (60BAh). (d)
5.
Use an external signal to turn off TPR1 (Touch probe 1). (e)
6.
Touch probe status (60B9h) remains "0003h", and the current position at the time TPR1 (Touch probe 1) turns off is not
stored as the Touch probe position negative value (60BBh). (f)
7.
Latching can be done continuously from (c). (g)
The following shows a timing chart.
High-precision touch probe
TPR2 (touch probe 2) supports high-precision touch probe. The normal touch probe has the latch function with precision of 55
s. On the other hand, the high-precision touch probe latches precisely startup of TPR2 (touch probe 2) with precision of 2
s.
To use the high-precision touch probe, set [Pr. PD37] to "_ _ _ 1". While the high-precision touch probe is being used, the
encoder pulse output function cannot be used. The precision of the falling edge is 55
s in this case as well.
