As shown in above figure, digital input circuit supports mechanical switch connection mode and
open collector connection mode of triode (NPN type and PNP type, mixed-use of these two
types is not allowed);
Users can use either the 24V power supply carried by the servo drive (it only can provide 100mA
current) or 12V~24V power supply provided by the user.

The maximum frequency of input pulse is 4MHz and the input signal voltage is ±5V;
With the best anti-noise capability, this signal transmit method is recommended as the preferred.
