Table 5: Signal output specifications
When using the digital inputs with the clock outputs for cross-wire detection for long
cable lengths, it must be ensured that the cable capacitance from the clock output to
the digital input does not exceed a value of 75 nF in relation to GND and that the
cable resistance does not exceed a value of 250 Ω, so that the cross-wire detection
does not detect a wiring fault if the wiring is correct.
