The DM860S is a two phase digital stepper driver based on 32-bit DSP technology. The microstep resolution and output current can be set by users. It has advanced control algorithm which brings a unique level of system smoothness, provides optimum torque and mid-range instability. The control algorithm of Multi-Stepping can allow stepper motor a smooth system performance. The control algorithm of torque compensation can improve the torque of motor at high speed. The control algorithm of motor self-test and parameter auto-setup offers optimum responses with different motors and easy-to-use. The control algorithm of smoothness can enhance the acceleration and deceleration of motor. Its unique features make the DM860S an ideal solution to applications.

Key Features:

  • Parameter auto-setup and motor self-test
  • Multi-Stepping inside, Small noise, low heat, smooth movement
