Product description:

The MD882 is a high performance microstepping drive based on pure-sinusoidal current control technology. Owing to that and the self-adjustment technology (self-adjust current control parameters) according to different motors, the driven motors can run with less noise, generating less heat, move smoother and have better performance at higher speed than most of the drives on the market.

Features:
  • High performance, low cost
  • Supply voltage up to +80VDC
  • Output current up to 8.2A
  • Output current selectable in 8 steps via DIP-switch
  • Automatic idle-current reduction (in standstill mode) to reduce motor heating; function switchable
  • Pure-sinusoidal current control technology
  • Pulse input frequency up to 300 kHz
  • TTL compatible and optically isolated differential inputs
  • 16 selectable resolutions in decimal and binary, up to 10,000 steps/rev
  • Suitable for 2-phase and 4-phase motors
  • Support PUL/DIR and CW/CCW modes
  • Short-voltage, over-voltage, over-current protections

Applications:

Suitable for a wide range of stepping motors of NEMA sizes 17, 23, 24 and 34 (42x42 mm to 86x86 mm). It can be used in various kinds of machines, such as X-Y tables, engraving machines, labeling machines, laser cutters, pick-place devices, and so on. Particularly well suited for applications where low noise levels, less heat development, high speed and high precision are desired.
