Features GOOD COMPATIBILITY: Digital display closed loop stepper motor driver, user can customize the number of microsteps, compatible with 1000 and 2500 line encoders. GOOD PERFORMANCE: Variable current control technology, high current efficiency, low vibration, low speed movement, ensuring stable and reliable operation. STABLE CONTROL: The stepper motor driver has internal acceleration and deceleration control, greatly improves the smoothness of motor start or stop. PROTECTION FUNCTION: With overcurrent, overvoltage and position out of tolerance protection, the green indicates operation, the red indicates protection or offline. EASY TO ADJUST: Can automatically adjust the current according to the load, reduce the temperature rise, improve the motor output torsion and working speed.
