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.

Driver

s reliable working temperature should be <60 , and motor working temperature should

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
