Stepper motor Driver DM860H 2phase For cnc Router/Laser Machine 7.2A, DC 18-80V driver for NEMA23 and NEMA34 motor
Feature of Driver for nema23 and nema34 motor:
1. Stable performance with digital signal processing high-Rate processor
2. High-accuracy positioning in low subdivision
3. With the latest PI current control algorithm, the output torsion is large, giving you extraordinary high-Rate performance.
4. Can adapt to the harsh environment and strong anti-interference ability
5. The parameter self-tuning function is integrated in the drive, which can generate different adaptation parameters for different motors, so that the motor can achieve the best performance.
