DMD870 Digital Stepper Drive

1. INTRODUCTION, FEATURES AND APPLICATIONS

Introduction

Motion Control Products Ltd (MCP)'s digital stepper drive DMD870 is a versatility fully
digital stepper drive based on a DSP with advanced control algorithm. The DMD870 is the
next generation of digital stepper controls. It brings a unique level of system smoothness,
providing optimum torque and nulls mid-range instability. Motor auto-identification and
parameter auto-configuration technology offers optimum responses with different motors
and easy-to-use. The driven motors can run with much smaller noise, lower heating,
smoother movement than most of the Drives in the markets. Its unique features make the
DMD870 an ideal solution for applications that require low-speed smoothness.
Compared to the DMD432 (DM432C), broader input voltage and output current ranges
make DMD870 being able to drive much more motors from size NEMA 17 to NEMA 34.
What's more, thanks to its higher performance DSP, driven motors can achieve much
higher speed (above 3000RPM), offering servo-like performances. DMD870 stepper drive
is regarded as an improved model originally from DMD556, while supports broader input
voltage range.
