    Function Description
    Functions Operation Instructions
    PWR Power Indicating Lamp When the driver is powered on, the green light is always on.
    ALARM Overcurrent/Undervoltage Indicator When the overvoltage and overcurrent faults occur, the red light is always on.
    PUL+ Positive End of Control Pulse Signal Connect to signal power,+5V to +24V can be driven.
    PUL- Negative End of Control Pulse Signal The falling edge is valid, and the motor takes one step whenever the pulse changes from high to low. Input resistance 220Ω. Requirements: low level 0 to 0.5V, high level 4 to 5V, pulse charge >2.5us.
    DIR+ Positive End of Directional Signal Connect to signal power,+5V to +24V can be driven.
    DIR- Negative End of Directional Signal Used to change the direction of the motor.Input resistance 220Ω. Requirements: low level 0 to 0.5V, high level 4 to 5V, pulse charge >2.5us.
    ENA+ Positive End of Enabling Signal Connect to signal power,+5V to +24V can be driven.
    ENA- Negative End of Enabling Signal When it is valid (low level), the motor coil current is turned off, the driver stops working, and the motor is in a free state.
    ALM+ Positive End of Alarm Signal Output When over-current, over-voltage, under-voltage or over-tolerance alarms, the alarm signal is valid (the output photocoupler is turned on). ALM+ is connected to the pull-up power to use the positive pole of the output power supply, and ALM- is connected to the negative pole of the output power supply. Maximum drive current 50mA.

    Tips: Power-off phase memory function of stepper motor driver

    The stepper motor driver is in a certain phase when the power is off. If the phase is different from this phase when the power is turned on the next time, the motor will jitter. In order to eliminate the jitter, the phase when the power is off must be memorized.

    The running sequence of the stepper motor is 8. If it stops at the 4th step, the board is powered off, and after the power is re-powered, if you directly start to drive the 1st step at the 4th position, there will be a skip. The stepper motor driver is an actuator that converts electrical pulses into angular displacement. When the stepper driver receives a pulse signal, it drives the stepper motor to rotate a fixed angle in the set direction, and its rotation runs step by step at a fixed angle. The stepper motor driver can control the angular displacement by controlling the number of pulses, so as to achieve the purpose of accurate positioning; at the same time, it can control the speed and acceleration of the motor rotation by controlling the pulse frequency, so as to achieve the purpose of speed regulation and positioning. If the system can still remember that it is still in step 4, it can correctly issue the command to go to step 5 or 3.

    Most stepper motor drivers do not have the power-down phase memory function, especially the stepper motor drivers that use common dedicated ICs. The reset signal of the reset pin after the dedicated IC is powered on will reset the motor phase to the initial value. The power-on jitter should be It is inevitable. Stepper motor drive Stepper motor cannot be directly connected to the power frequency AC or DC power supply to work, but must use a dedicated driver. As shown in the figure, it is composed of a pulse generation control unit, a power drive unit, and a protection unit. The two units enclosed by the dot-dash line in the figure can be controlled by a microcomputer.

    Great product at an affordable price!
    This digital stepper motor driver works well and delivery was quick. Smooth operating for Nema 34 2 phase stepper motor. No problems so far on my CNC router. Ran it over 24 ho hours continues without any issues. Highly recommend this stepper controller.
