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

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.
