• Top-level Quality, Affordable Price
• Professional Driver, Manufactured by Leadshine
• Speed self-adjustment technology
• Easy current subdivision setting
• Suit for Nema 8, 11, 14, 16, 17 Stepper

This is a digital stepper drive implemented with advanced stepper control technology. It is easy to use and it can be used to drive 2-phase and 4-phase motors(from Nema 11-Nema 17 size) smoothly with less heat and noise. It works with 10-30VDC voltage and can provide max 2.2A peak current. You can set the DIP switches to get the current and microsteps you need. Key Features: *Anti-Resonance for optimal torque, extra smooth motion, low motor heating and noise *Motor auto-identification and parameter auto-configuration for optimal torque from wide-range motors *Step & direction (PUL/DIR) control *Multi-Stepping for smooth motor movement *Optically isolated inputs *Input voltage 18-30VDC *8 selectable micro-step resolutions of 400-12800 via DIP switches *8 selectable output current settings of 0.3 – 2.2A via DIP switches *Soft-start with no “jump” when powered on *Pulse input frequency up to 60 KHz *Automatic idle-current reduction *Protections for over-voltage and over-current Electrical Specifications: *Output Peak Current: 0.3~2.2A (1.6 RMS) *Input Voltage: +10~30VDC *Logic Signal Current: 7~16mA (Typical 10mA) *Pulse Input Frequency: 0~60kHz *Isolation Resistance: 100MΩ 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: 50℃ MAX *Vibration: 10-50Hz / 0.15mm *Storage Temperature: -20℃ － 65℃ *Weight: Approx.90g (3.5oz) Warning: Make sure the motor connect to a constant current or chopper drive controller before you test motor. Connecting the motor directly to a power supply will destroy the motor.
