The driver supports universal pulse signals of 3.3 V, 5 V, or 24 V without the need for series resistors. The power supply input is 9–40 V DC (24 V DC recommended).Frequently Asked QuestionsQ: How can I quickly get started with this stepper motor driver for the first time?A: After correctly connecting the power supply and motor, connect only the pulse signal (set the frequency to within 1K first) with microstepping set to 16. Leave the direction and off-line pins floating. At this point, when power is applied, the motor will rotate clockwise by default. Once operation is confirmed, test the acceleration (increase frequency), direction, microstepping, and off-line functions one by one.Q: If the control signal exceeds 5V, is it necessary to add a series resistor?A: Yes, otherwise the driver’s control interface circuitry may be damaged.Q: The power indicator lights up after wiring, but the motor does not rotate. What is the cause?A: If the wiring is correct but the motor still does not rotate, it indicates insufficient drive capability in the control section. This situation typically occurs when using direct control via a microcontroller’s front-end I/O port. Please ensure the control interface has a drive capability of 5mA.Q: How do I determine the pin assignments for the four wires of a stepper motor?A: Connect any two wires of the motor together. If you feel resistance when turning the motor rotor by hand, these two wires belong to the same phase and can be connected to the driver’s A+ and A- terminals. If shorting the other two wires together still results in resistance, connect these two wires to the B+ and B- terminals.Package ContentsStepper Motor Driver *1
