<b>Overview: </b><br><br> This driver is an industrial-grade fully digital stepper drive developed with advanced DSP control algorithm based on the latest motion control technology. <br> Its motor auto-identification and parameter auto-configuration feature offers quick setup to optimal modes with different motors. <br> Compared with other analog or TB6600 chips driver, it can drive a stepper motor at much lower noise, lower heating, and smoother movement. <br> <br> <b>Key Features: </b><br><br> * Anti-Resonance provides optimal torque and nulls mid-range instability<br> * Motor auto-identification and parameter auto-configuration when power on, offer optimal responses with different motors<br> * Multi-Stepping allows a low resolution step input to produce a higher microstep output, thus offers smoother motor movement<br> * 15 selectable microstep resolutions: 1/2, 1/4, 1/5, 1/8, 1/10, 1/16, 1/20, 1/25, 1/32, 1/40, 1/50, 1/64, 1/100, 1/125, 1/128<br> * Soft-start with no “jump” when powered on<br> * 8 selectable peak current including 1.00A to 4.20A<br> * Pulse input frequency up to 200 KHz, TTL compatible and optically isolated input<br> * Automatic idle-current reduction<br> * Suitable for 2-phase and 4-phase motors<br> * Support PUL/DIR mode<br> * Over-voltage and over-current protections<br><br> <b>Electrical Specifications:</b> <br><br> * Output Peak Current: 1.0~4.2A (3.0 RMS)<br> * Input Voltage: +20~50VDC (Typical 36VDC)<br> * Logic Signal Current: 7~16mA (Typical 10mA)<br> * Pulse Input Frequency: 0~200kHz<br> * Pulse Width: 2.5μS<br> * Isolation Resistance: 500MΩ<br> * Cooling: Natural Cooling or Forced cooling<br> * Environment: Avoid dust, oil fog and corrosive gases<br> * Operating Temperature: -10℃~45℃ <br> * Vibration: 10-55Hz / 0.15mm<br> * Weight: Approx.210g (7.4oz)<br><br> <b>Packing List: </b><br><br> 1 x Stepper Driver DM542T <br> 1 x Full DM542T Driver Manual
