SOMANET Circulo: Perfect servo drive for collaborative robots.

With its circular shape and hollow shaft with a diameter of 20 mm SOMANET Circulo 7 is ideal for a fully integrated Axis which are mainly used in Collaborative Robots. SOMANET Circulo servo drives can have up to two integrated absolute encoders (19 bits) with a battery-based multi-turn option which automatically calibrates. In addition, the nodes offer on-board safety features such as STO and SBC via a 24V I/O. Because the cable connections can easily be looped through, the wiring for EtherCAT, Logic Voltage, STO and SBC are extremely simple. In addition, there is an interface to external encoders for ABZ, SSI, BiSS-C and A-format. SOMANET Circulo also offers an interface and mechanical device for a Cobot-type locking brake and a motor temperature sensor (PT100, PT1000, KTY).

  • hollow shaft for optimized cable guiding
  • 2 internal encoders (optional)
  • battery-based multi-turn option
  • optional integrated brake
  • STO/SBC on-board
  • external encoder interface for ABZ, SSI, BiSS-C and A-format
  • modular structure for fast modification
  • torque-based performance control
  • smart brake
  • Dual-Loop Control
  • Model-predictive Field-oriented Control, allow a low heat dissipation of the drives while keeping up high motion control frequencies

SOMANET Circulo is specifically designed for the needs of Collaborative Robotic Arms.
