Type1 digital input interface
Power supply by the user, DC12~24V, current ≥100mA;
Note that if the current polarity is reversed, the servo drive will not work.

Type2 digital output interface
The output is a Darlington transistor connected to a relay or optocoupler;
The external power supply is provided by the user, but it must be noted that if the polarity of
the power supply is reversed, the servo drive will be damaged;
The output is in the form of an open collector with a maximum current of 50mA and an
external power supply with a maximum voltage of 25V.Therefore, the load of the digital
output signal must meet this limit.If the limit is exceeded or the output is directly
