1. Introduction, Features and Applications

Introduction
The DM422C is a versatility fully digital stepping Drive based on a DSP with advanced control
algorithm. The DM422C 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 self-test and parameter auto-setup 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 DM422C
an ideal solution for applications that require low-speed smoothness. Compared to the DM432C,
the DM422C has smaller size and lower cost.
Features
 Anti-Resonance, provides optimum torque
and nulls mid-range instability
 Motor self-test and parameter auto-setup
technology, offers optimum responses with
different motors
 Multi-Stepping allows a low resolution step
input to produce a higher microstep output
for smooth system performance
 Microstep resolutions programmable, from
full-step to 102,400 steps/rev
Applications
Suitable for a wide range of stepping motors, from NEMA frame 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 DM422C an ideal solution for applications that
require low-speed smoothness.

Elimination of Heat
Drive's reliable working temperature should be <70℃(158℉), and motor working temperature

should be <80℃(176℉);
It is recommended to use automatic idle-current mode, namely current automatically reduce to

60% when motor stops, so as to reduce Drive heating and motor heating;
The Drive must be mounted vertically to maximize heat sink area as shown in the following

picture. Use forced cooling method to cool the system if necessary.
