1. Introduction, Features and Applications
Introduction
The MA860 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.
Features
l High performance, cost-effective
l Supply voltage up to 60VAC or +80VDC
l Output current up to 7.2A
l Self-adjustment technology
l Pure-sinusoidal current control technology
l Pulse input frequency up to 300 KHz
l TTL compatible and optically isolated input
Applications
Suitable for a wide range of stepping motors, from NEMA size 17 to 43. It can be used in various
kinds of machines, such as X-Y tables, labeling machines, laser cutters, engraving machines,
pick-place devices, and so on. Particularly adapt to the applications desired with low noise, low
heating, high speed and high precision.
