1. Introduction, Features and Applications 

Introduction 

The  MA860HH  is  a  high  performance  microstepping  driver  based  on  pure-sinusoidal  current 
control technology. Owing to the above technology and the self-adjustment technology (self-adjust 
current  control  parameters)  according to different  motors, the  driven  motors  can  run  with smaller 
noise, lower heating, smoother movement and have better performances at higher speed than most 
of the drivers in the markets. It is suitable for driving 2-phase and 4-phase hybrid stepping motors.
