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.
Features
l Anti-Resonance, provides optimum torque
and nulls mid-range instability
l Motor auto-identification and parameter
auto-configuration
technology,
offers
optimum responses with different motors
l Multi-Stepping allows a low resolution step
input to produce a higher microstep output
for smooth system performance
l Microstep resolutions programmable, from
full-step to 51,200 steps/rev
Applications
Suitable for a wide range of stepping motors, from NEMA size 14 to 23. It can be used in various
kinds of machines, such as laser cutters, laser markers, high precision X-Y tables, labeling machines,
and so on. Its unique features make the DM432 an ideal solution for applications that require
low-speed smoothness.

Driver's reliable working temperature should be <60 , and motor working temperature should
be <80 ;

l
It is recommended to use automatic idle-current mode, namely current automatically reduce to
60% when motor stops, so as to reduce driver heating and motor heating;
l
It is recommended to mount the driver vertically to maximize heat sink area. Use forced cooling
