By implementing advanced DSP current control algorithm, Leadshine EM705 is a advanced high performance 2-phase digital stepper drive. It takes step & direction or CW/CCW control commands, and is very simple to implement in OEM applications.

Without an external sensor such as an encoder, the EM705 stepper drive can automatically identify 100% of stall of driven motors at 300 RPM or above, and send fault signals back to motion controller or other devices The EM705 stepper drive also adopts advanced features like electrical damping, anti-resonance, start-up smoothing, multi-stepping. It is capable of driving a wide range of 2-phase stepper motors with high precision at extra smoothness, quietness, and very low motor heating. Its Multi-Stepping feature allows a low resolution step input to produce a much higher microstep output for smoother & quiet motor movement, and much lower motor heating. This will significantly improve the performance of your stepper control systems.

The EM705 stepper drive is easy to setup and configure via DIP switches. Also, a user can simply set the idle current to full (100%) or 50% of the output current via a DIP switch. Its motor auto identification and drive self-configuration feature allows quick and easy setup for various motors at optimal performance.

Leadshine also offers matched stepper motors for the EM705 with their optimized configurations stored in the stepper drive. The user only needs to use the motor rotary switch to select the right motor, and the EM705 will automatically load the pre-setting optimized settings for best performance.

For driving a non-Leadshine stepper motor, a user can use the 'Motor Auto Identification and Configuration' feature of the EM705 to get optimized performance.

For advanced users, Leadshine offers tuning software for performance fine-tuning. The user can tune a stepper motor's three resonance areas (usually around 1 rps, 2 rps, and 4 rps) to reduce noise and vibration, set microstep resolution to any value from 200 to 104,000 (increase by 200), and configure output current to any value of 0.5 to 7.00 A (increased by 0.1A) and idle current of 1 to 100% of output current.

Features:

  • Sensorless stall detection
  • Extra-low motor noise offers excellent quietness
  • User password protection prevents others from copying your drive configurations
  • Optimizes torque and nulls mid-range instability
  • Self-test and Auto-configuration technology
  • Options to set output current and microstep resolutions via DIP switch or software
  • Automatic idle-current reduction and reduction rate is software configurable
  • Fault out prevents damages to your machines or the materials
