1. Introduction, Features and Applications
Introduction
The DM432 is a versatility fully digital stepping driver based on a DSP with advanced control
algorithm. The DM432 is the next generation of digital stepping motor 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 drivers in the markets. Its unique features make the
DM432 an ideal solution for applications that require low-speed smoothness.
