12.3.8 Touch Probe function (Position capture function and position
capture status)
The Touch Probe function can be triggered by high-speed digital inputs (only DI1 and DI2 with
the hardware response 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 the DI of CN1, note the following:
1. To capture the motor Z pulse, you can only set it with Touch Probe 1. Regardless of the
settings of OD 60B8 Bit 4 and Bit 5, the command is rising-edge triggered and the data is
stored in OD 60BA.
2. When the capture source is set to the DI of CN1, the previously set function code for the DI
will be 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.
