5.5 Touch probe

The touch probe function that executes current position latch by sensor input can be used.
With this function, the position feedback of the rising edge and falling edge of TPR1 (touch probe 1) and
TPR2 (touch probe 2) or the position feedback of when the encoder zero point was passed through can be
stored into each object of 60BAh to 60BDh according to the conditions specified in Touch probe function
(60B8h).
The following shows the touch probe detection resolution. Enabling the high precision touch probe will
disable the encoder output pulses.
