Brief Introduction
2MSD7880 is a high performance microstepping driver, it is suitable for driving any 2-phase and 4-phase hybrid step motors of NEMA34 & 43 with up to 8.0A per phase current capability.
 
Based on the build-in advanced module, the driver using sinusoidal wave current control technology, so the stepper motor work with more speed and power.  The input voltage ranges from 24VDC – 80VDC. 
 
Features
  •          Low noise, high stability
  •          14 selectable resolutions (decimal & binary)
  •          Special control circuit lowers noise and enhances stability
  •          Bi-polar constant chopping technology provides high speed and power
  •          Idle-current selection (with SW4)
  •          Opto-isolated input/output signals
  •          DIP switch current setting with 8 different value, up to 7.8A peak
  •          Input voltage from DC24-80V
  •          Size of 119 x 97 x 48 mm
 
Applications
2MSD7880 can be used for 2-phase hybrid stepping motors of NEMA34 & 43 with a phase current of up to 8.0A, it’s suitable for a wide range of machines, such as lighting machines, roboticized machines, instruments, POS machines, engraving machines, labeling machines, laser cutters, packaging machines and semiconductor devices.
