Overview The MA860H is a high performance microstepping driver based on pure-sinusoidal currentcontrol 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.

Key Features High performance, cost-effective Supply voltage up to 50DC Output current up to 4.5A Self-adjustment technology Pure-sinusoidal current control technology Pulse input frequency up to 300 KHz TTL compatible and optically isolated input Automatic idle-current reduction 16 selectable resolutions in decimal and binary, up to 51,200 steps/rev Suitable for 2-phase and 4-phase motors Support PUL/DIR and CW/CCW modes Short-voltage, over-voltage, over-current protections
