When the touch probe function (60B8h) is set, and TPR1 (Touch probe 1) and TRP2 (Touch probe 2), external signals, are
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 Touch probe status (60B9h). The latched current data can be
read with Touch probe pos1 pos value (60BAh) and Touch probe pos1 neg value (60BBh). The following shows the touch
probe detection resolution. Enabling the high precision touch probe disables the encoder output pulses. For details of each
object, refer to sections 10.4.9 to 10.4.14.
