Generic M880A Microstepping Stepper Motor Controller  (Multicolor)

M880A Microstepping Stepper Motor Controller 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. Skill Level : Assembled and Tested Features: High performance Supply voltage up to +80VDC M880 output current up to 7.8A M840 output current up to 3.9A Inaudible 20kHz chopping frequency TTL compatible and optically isolated input signals Automatic idle-current reduction Mixed-decay current control for less motor heating 14 selectable resolutions up to 51,200 steps/rev Suitable for 2-phase and 4-phase stepping motors Over-current, over-voltage protection Small size (M880:119 x 97 x 48 , M840:119 x 97 x 31) Introduction: The M880/M840 are high performance microstepping drivers based on one of the most advanced technologies in the world today.
