Functions Operation Instructions
Signal Interface PUL PUL+ is the positive end of the control pulse signal PUL- is the negative end of the control pulse signal
DIR DIR+ is the positive end of directional signal DIR- is the negative end of directional signal
ENA ENA+ is the positive end of enabling signal ENA+ is the negative end of enabling signal
Motor Interface A A+ is connected with the positive end of the A phase winding of the stepping motor A- is connected with the negative end of the A phase winding of the stepping motor
B B+ is connected with the positive end of the B phase winding of the stepping motor B- is connected with the negative end of the B phase winding of the stepping motor
When the A and B two phase windings are switched, the motor direction is reversed
Indicator Light 1. The green light is the power indicating lamp. When the drive is powered on, the green light is always on. 2. The red light is the fault indicating lamp. When the overvoltage and overcurrent faults occur, the trouble lamp is always on.
Note: The default input signal is 5V pulse signal. When 24V input signal is required, please in series with1.8-2kΩ resistance.

Digital Stepper Driver 1-4.2A 20 50V DC for Nema 17 Details

Tips: The role of stepper driver’s subdivision
Major advantages of subdivided driver: Low frequency oscillation of motor is completely eliminated. Low frequency oscillation is the intrinsic characteristic of the stepper motor (especially VR motor). However, subdivision is the only way to eliminate it. If your stepper motor has to work at resonance region (e.g.: run arc) sometimes, it is the only choice to choose subdivided driver to increase the output torque of the motor. Especially for 3-phse VR motor, its torque is increased by about 30-40% when not subdivided. Thus, the resolution of the motor is increased. With the stepping angle reduced and uniformity of the step pitch increased, the resolution of the motor is self-evident. The main role of stepper motor driver’s subdivision is to enhance the accuracy of the stepper motor.

Wonderful digital stepper driver
I'm very happy with this digital stepper driver. I bought three nema23 digital stepper drivers, two to drive the X axis and one to drive the Y axis. It is very easy to use. So I want to recommend it to everyone.
