Description
1
P24760 bit 0, 4, 5 = 1
Enables Touch Probe1. The rising edge and falling edge are enabled.
2
→ P24761 bit 0 = 1
Turns on the Touch Probe1 enable status.
3
Turns on Touch Probe Signal (TPR1).
4
→ P24761 bit 1 = 1
Turns on the Touch Probe1 positive edge stored status.
4a
→ P24762
Sets the latched position feedback for Touch probe position1 positive value.
5
Turns off Touch Probe Signal (TPR1).
6
→ P24761 bit 2 = 1
Turns on the Touch Probe1 negative edge stored status.
6a
→ P24763
Sets the latched position feedback for Touch probe position1 negative value.
7
P24760 bit 4 = 0
Turns off Sample positive edge. Rising edge detection is disabled.
8
→ P24761 bit 1 = 0
Turns off Touch Probe1 positive edge stored status.
8a
→ P24762
Touch probe position1 positive value does not change.
9
P24760 bit 4 = 1
Turns on Sample positive edge. Rising edge detection is enabled.
10
→ P24762
Touch probe position1 positive value does not change.
11
Turns on Touch Probe Signal (TPR1).
12
→ P24761 bit 1 = 1
Turns on the Touch Probe1 negative edge stored status.
12a
→ P24762
Sets the latched position feedback for Touch probe position1 negative value.
13
P24760 bit 0 = 0
Disables Touch Probe1.
14
→ P24761 bit 0, 1, 2 = 0
Clears all the status Bit.
14a
→ P24762, P24763
Touch probe position1 positive/negative value does not change.
(5) High-precision touch probe
Touch probe 2 supports high-precision touch probe. The normal touch probe has the latch function with
precision of 55 μs. On the other hand, the high-precision touch probe latches precisely startup of TPR2
(touch probe 2) with precision of 2 μs. 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 falling edge is 55 μs in this case as well.
