DM542 Digital Stepper Motor Driver 20-50VDC 1.0-4.2A
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.
Features
- 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.
- 15 selectable microstep resolutions 400 – 25600 steps/rev.
- Soft-start with no “jump” when powered on.
- Support PUL/DIR and CW/CCW modes.
- Optically isolated inputs (5–24 V).
- Over-voltage, over-current protections.
