13.3.8 Touch Probe function and Touch Probe status
13
The Touch Probe function can be triggered by high-speed digital inputs (only DI1 and DI2, with
the hardware response time up to 5 µs) or by the motor Z pulse. This function is used for
high-speed measurement or packaging applications.
If the capture source is the motor Z pulse or DI of CN1, note the following:
1. When the capture source is set to the motor Z pulse, you can only use Touch Probe 1.
Regardless of the settings of OD 60B8h [Bit 4] and [Bit 5], the command is rising-edge
triggered and the data is stored in OD 60BAh.
2. When the capture source is set to the DI of CN1, the previously set function code for the DI
is changed to 0x0100 so one DI does not have two functions.
Set the Touch Probe function with OD 60B8h. The definition of each bit is as follows.

Description
0: disable Touch Probe 1.
1: enable Touch Probe 1.
0: capture one time. If the Touch Probe 1
signal is set to be both rising-edge and
falling-edge triggered, the data is
captured once for each triggering.
1: capture multiple times.
0: DI1 of CN1
1: motor Z pulse
-
0: N/A
1: start capturing when the Touch Probe
1 signal is rising-edge triggered and
store the data in OD 60BAh.
0: N/A
1: start capturing when the Touch Probe
1 signal is falling-edge triggered and
store the data in OD 60BBh.
-
0: disable Touch Probe 2.
1: enable Touch Probe 2.
0: capture one time. If the Touch Probe 2
signal is set to be both rising-edge and
falling-edge triggered, the data is
captured once for each triggering.
1: capture multiple times.
0: DI2 of CN1
-
0: N/A
1: start capturing when the Touch Probe
2 signal is rising-edge triggered and
store the data in OD 60BCh.
