SOMANET Node controls and drives one permanent magnet synchronous motor (PMSM, BLDC) up to 2080 Watt peak power.

SOMANET Node: Meet the most compact and flexible embedded EtherCAT servo drives.

  • Highly efficient model-predictive, field-oriented motor control software with advanced compensation of unwanted physical effects in drive (e.g. cogging)
  • EtherCAT or Ethernet communication (Profinet, SERCOS III, CAN, RS-485, WiFi and Bluetooth available on demand)
  • DS402 position, speed and torque/current control loops
  • High-res, high-speed ADCs for precise current and voltage measurements
  • Advanced protection circuitry
  • Control feedback through encoders and additional sensors via Hall, QEI/ABI/ABZ (RS-422), BiSS-C (RS-422), SSI, SPI, I2C and analog interfaces

Applications for the SOMANET Node include for example:

  • Traditional Robotic Arms
  • Collaborative Robotic Arms
  • Automated Guided Vehicles
  • Service Robots
  • Conveyor Belts
  • Special Machinery
