Digital Input Wiring Diagram (Source type connection, example)
9.14.4.1 Digital Inputs 1 and 2
These inputs (X7/9 and X7/10) are particularly fast and are therefore suitable for position
latch functions. They can also be used as 24 V inputs for electronic gearing (
Technical characteristics
Floating, reference common line is DCOM7
Sink or Source type sensors possible
High: 3.5 to 30 V/2 to 15 mA , Low: -2 to +2 V/<15 mA
Update rate: firmware reads hardware input state every 250 µs
High accuracy latch: motor feedback position or interpolated time is latched or captured
within 2 µs of input signal transition (with digital input filter set to 40 ns)
The AKD capture engine is polled every 62.5 µs (16 kHz) by the firmware
For KAS applications (example: AKD PDMM), the latch position information is updated in
the Ethercat PDO. The typical update time into the KAS project is two Ethercat cycles (
with each cycle being 250 µs, 500 µs, 1000 µs, or 2000 µs)
