Product description:

The DM805-AI is a 0 – 5 V input stepper drive with built-in oscillator which is based on the latest digital control algorithm. It brings a unique level of system smoothness, providing optimum torque and nulls mid-range instability. Motor self-test and parameter auto-setup technology offers optimum responses with different motors and easy-to-use. The driven motors can run with much smaller noise, lower heating, smoother movement than most of the drivers in the markets. Its unique features make the DM805-AI an ideal solution for applications that require low-speed smoothness.

The three built-in potentiometers are used to preset and adjust the velocity, acceleration and deceleration. In 0-5 V speed mode, the motor speed is controllable and follows the analog 0 - 5 V input. In high / low speed mode, the motor speed is selected by digital input and adjusted by the high/low speed potentiometers. The user can run the motor with the least configuration and connection. In position mode, the DM805-AI is a traditional stepper drive. There is a 5 V power supply output for customer use.

Features:
  • Anti-Resonance, provides optimum torque and nulls mid-range instabilities
  • Motor self-test and parameter auto-setup technology, offers optimum responses with different motors
  • Multi-Stepping allows a low resolution step input to produce a higher microstep output for smooth system performance
  • Command Source: 0-5V, built-in potentiometer and pulse
  • Two preset velocities, adjustment by built-in potentiometers
  • Preset acceleration / deceleration and adjust by built-in potentiometer
  • Velocity control mode via 0-5 V or position control mode via pulse
  • Built-in pulse generator nulls external motion controller
  • Supply voltage up to +80 VDC (recommended not to exceed 72 V because of “back EMF”)
  • Output current programmable, from 0.3 A-5.0 A (RMS)
  • TTL compatible and optically isolated digital input
  • Automatic current reduction
  • Over-voltage, over-current, phase-error protections
