EM Series - Advanced DSP-Based Digital Stepper Drives with Sensorless Stall Detection Function


Highlights

  • Advanced DSP-based current control algorithm
  • Sensorless stall detection
  • Low-middle speed anti-resonance
  • Extra low noise; extra low motor heating; smooth motor movement
  • Stored configurations for matched stepper motors of NEMA 14, 16, 17, 23, and 34
  • Easy setup via DIP switches for microstepping resolution and output current
  • Free software for fine tuning, output current, resolutions...
  • Automatic stepper motor identification and self configuration
  • Step & direction or CW/CCW control (EM402 and EM806 only support step & driection)

By implementing the advanced detection and control algorithms, Leadshine's EM series DSP-based stepper drives deliver excellent performance not available before. Unique features of sensorless stall detection, extra smoothness and excellent high speed performance make the EM stepper drives deliver servo-like performance at the cost of stepper drives. They are capable of delivering high performance for motion control and identifying stepper motor movement stall which can prevent potential damages to your machines or the materials.

 

Leadshine's EM series stepper drives are able to drive stepper motors from NEMA 8 to NEMA 42 at very smooth movements with very low motor and drive heating. Compared with most analog stepper drives, noise can be reduced up to 70%. Taking step & direction control commands, the EM series stepper motor drives are easy to set up. There is a wide choice for the EM stepper motor drives to suit input voltage from 18 to 80 VDC, and output current of 0.3 to 8.2A.
