1. There are three input signals, they are: Step pulse signal PUL+, PUL-; Direction level signal DIR+, DIR- Offline signal EN+, EN-. There are two connection methods for the input signal interface. Users can use common anode connection or common cathode connection according to their needs.
The ENA terminal does not need to be connected. When the ENA is activated, the motor rotor is free (offline). At this point, you can manually rotate the motor shaft to make the adjustment that suits you. After the manual adjustment is complete, set the ENA to the inactive state and continue with the automatic control.
