Digital Stepper Driver 1.0-4.2A 20-50VDC For Nema 17, 23, 24 Stepper DM542

Description: 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. Key Features: Input voltage 20-50VDC Anti-Resonance provides optimal torque and nulls mid-range instability Motor auto-identification and parameter auto-configuration when power on, offer 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 including 400, 800, 1600, 3200, 6400, 12800, 25600, 1000, 2000, 4000, 5000, 8000, 10000, 20000, 25000 Soft-start with no “jump” when powered on 8 selectable peak current including 1.00A, 1.46A, 1.91A, 2.37A, 2.84A, 3.31A, 3.76A, 4.20A Pulse input frequency up to 200 KHz, TTL compatible and optically isolated input Automatic idle-current reduction Suitable for 2-phase and 4-phase motors Support PUL/DIR mode Over-voltage and over-current protections Electrical Specifications: Output Peak Current: 1.0~4.2A (3.0 RMS) Input Voltage: 20~50VDC (Typical 36VDC) Logic Signal Current: 7~16mA (Typical 10mA) Pulse Input Frequency: 0~200kHz Pulse Width: 2.5μS Isolation Resistance: 500MΩ Operating Environment and other Specifications (Tj = 25℃/77℉): Cooling: Natural Cooling or Forced cooling Environment: Avoid dust, oil fog and corrosive gases Ambient Temperature: 0℃ － 65℃ Humidity: 40%RH－90%RH Operating Temperature: -10℃ － 45℃ Vibration: 10-55Hz / 0.15mm Storage Temperature: -20℃ － 65℃ Weight: Approx.210g (7.4oz) What you will receive: 1 x  Digital Stepper Motor Driver Controller Notes: Due to motor inductance, the actual current in the coil may be smaller than the dynamic current setting, particularly under high speed condition.
