User Manual

The DM542 is a fully digital stepper drive developed with advanced DSP control algorithm based on the latest motion control technology. It has achieved a unique level of system smoothness, providing optimal torque and nulls mid-range instability. Its motor auto-identification and parameter auto-configuration feature offers quick setup to optimal modes with different motors. Compared with traditional analog drives, DM542 can drive a stepper motor at much lower noise, lower heating, and smoother movement. Its unique features make DM542 an ideal choice for high requirement applications.



  • Anti-Resonance provides optimal torque and nulls mid-range instability 
  • Motor auto-identification and parameter auto-configuration technology, offers optimal responses with different motors 
  • Multi-Stepping allows a low resolution step input to produce a higher microstep output, thus offers smoother motor movement
