Feature: 1. Load Condition Support: Our digital display closed loop 57 stepper motor driver is suitable for all mechanical load conditions, including low stiffness pulleys and wheels, without the need to adjust gain parameters. 2. Low Vibration: The digital display 57 stepper motor driver allows the motor to work smoothly with low vibration and high dynamic performance during acceleration and deceleration. 3. Multiple Protection: The closed loop 57 stepper motor driver has overcurrent, overvoltage and position overrun protection. 4. Automatic Current Adjustment: The stepper motor driver improves the motor output torsion and working speed, and can automatically adjust the current according to the load to reduce the temperature rise. 5. Applicable Models: Display closed loop 57 stepper motor driver is suitable for driving 2.2Nm to 3Nm motors for nema23 and for nema24 series.
