Page 3: Introduction, Features And Applications
Electrical Specifications (T = 25℃) Introduction DM432 The DM432 is a versatility fully digital stepping driver based on a DSP with advanced control Parameters Typical Unit algorithm. The DM432 is the next generation of digital stepping motor controls. It brings a unique Output current 3.2 (2.3 RMS) -
Page 4: Operating Environment And Other Specifications
The DM432 can accept differential and single-ended inputs (including open-collector and PNP More detailed descriptions of the pins and related issues are presented in section 4, 5, 9. output). The DM432 has 3 optically isolated logic inputs which are located on connector P1 to accept Connector P1 Configurations line driver control signals. -
Page 5: Connecting The Motor
5. Connecting the Motor motors should be run at only 70% of their rated current to prevent over heating. The DM432 can drive any 2-pahse and 4-pahse hybrid stepping motors. Connections to 4-lead Motors 4 lead motors are the least flexible but easiest to wire. Speed and torque will depend on winding Figure 6: 6-lead motor full coil (higher torque) connections inductance. -

7. Selecting Microstep Resolution and Driver Output Current The DM432 can match medium and small size stepping motors (from NEMA frame size 14 to 23) made by Leadshine or other motor manufactures around the world. To achieve good driving Microstep resolutions and output current are programmable, the former can be set from full-step to performances, it is important to select supply voltage and output current properly. -

Page 14: Anti-Resonance Introduction
The Notes: DM432 driver provides robust anti-resonance control to stop the vibrations and maintain equilibrium. This feature requires that the driver be configured with respect to the total inertia in the system. If set However, if the user does not want to tune the current loop after changing a different stepping motor, improperly, the effectiveness of the feature may be diminished. -

DM432 Digital Stepping Driver Manual V1.0 DM432 Digital Stepping Driver Manual V1.0 ResonanceArea: Parameters for 3 resonance area. Usually between 2.4rps and 4.8rps. Default making it more difficult to find proper adjustment values. Optimum AMP(s) and Phase(s) values may be a little different between running the tests with an unloaded motor and a load motor. - Page 16 DM432 Digital Stepping Driver Manual V1.0 DM432 Digital Stepping Driver Manual V1.0 OverCurrent: Over-current Protection. Protection will be activated when continuous current exceeds 16A. OverVoltage: Over-voltage Protection. When power supply voltage exceeds 42±1 VDC, protection will be activated.
