    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: The stepper motor must match the corresponding stepper driver to work

    The stepper motor cannot be installed separately in the corresponding equipment, it must be matched with the corresponding stepper driver. The stepper motor needs to cooperate with the driver to receive the digital signal of the CPU, PLC and other controllers.

    Stepper motor driver is an actuator that converts electrical pulses into angular displacement. The angular displacement can be controlled by controlling the number of pulses, so as to achieve the purpose of accurate positioning. At the same time, the speed and acceleration of the motor rotation can be controlled by controlling the pulse frequency, so as to achieve the purpose of speed regulation and positioning. The subdivision technology is essentially an electronic damping technology, and improving the running accuracy of the motor is only an incidental function, and the main purpose is to reduce or eliminate the low-frequency vibration of the motor.

    For example, for a two phase hybrid bipolar stepper motor with a step angle of 1.8°, if the subdivision number of the subdivision driver is set to 4, the motor's operating resolution is 0.45° per pulse. However, whether the accuracy of the motor can reach or connect to 0.45° depends on the subdivision current control precision of the subdivision driver and some other factors.

    To reduce the working noise of the stepper motor, the subdivision driver is usually chosen, especially when the motor is working at a low speed, the vibration and noise of the motor will be more obvious. It is recommended to use a subdivision driver to alleviate this situation and promote the improvement of the vibration and noise of the motor at low speeds.

    2 phase stepper motor driver runs smoothly
    Great stepper motor driver, suitable for all kinds of projects. It is very easy to set up. I ran it on a Nema17 stepper motor and it worked perfectly. I am very satisfied with it.
