User's Manual for the M880A in pdf format

Introduction
The M880/M840 are high performance microstepping drivers based on one of the most advanced technologies in the world today. They are suitable for driving any 2-phase and 4-phase hybrid step motors. By using advanced bipolar constant-current chopping technique, they can output more speed and power from the same motor, compared with traditional technologies such as L/R drivers. Its 3-state current control technology allows coil current to be well controlled, with relatively small current ripple and results in less motor heating.

Applications
Suitable for a wide range of stepping motors of size Nema23 and 43, and usable for various kinds of machines, such as X-Y tables, labeling machines, laser cutters, engraving machines, and pick-place devices. Extremely suitible for applications expected to be low vibration, high speed and high precision.
