DM860 is a digital two-phase stepper motor drive launched by Leisai company. It adopts digital PID technology, has 16 gear divisions and 8 current options, which can meet the application needs of most occasions. It adopts the built-in acceleration and deceleration technology, which can be more stable in the process of starting and stopping. The built-in anti-resonance algorithm makes the low-speed and high-speed operation very stable and low noise. The drive has built-in parameter auto-tuning function, which can automatically generate adaptive parameters for different motors to better play the performance of the motor.
