4.7.1 Digital inputs on X25A (standard functions)
The digital inputs are provided for axis-related tasks, e.g. hardware limit switches. They
can be programmed individually via the EtherCAT bus system. The inputs DI09 and DI10
are suitable for touch probe applications due to their fast signal processing. In addition,
the standard digital input DI08 can be used for touch probe tasks. Each servocontroller
axis supports two touch probe inputs, with a fixed assignment to the inputs
(see Table 3.16). The axis assignment can also be programmed via the EtherCAT bus
system.

The internal signal delay due to the hardware propagation times is compensated
by the software. There are the following inaccuracies:
DI08
- Inaccuracy pos. edge /- 0.75 µs
- Inaccuracy neg. edge /- 5.5 µs
DI09 and DI10
- The inaccuracies are negligible.
