CIRCULO IS…

…A FULL FEATURED SERVO DRIVE

Whether you are planning a collaborative robotic arm, a service robot or an automated logistics solution:With our compact and efficient, high-performance, decentral servo drives, OEMs such as robot manufacturers and machine builders can utilize Synapticon’s advanced motion control technology to realize better products inless time. 

  • Works with any type of PMSM/BLDC motor up to 60V and 60Arms
  • Model-predictive Field-oriented Control for high efficiency, maximum bandwidth
  • Dual-loop control, gain-scheduling, high frequency control loops
  • EtherCAT interface with high frequency (up to 4kHz), low latency, negligible jitter
  • Support for 2 position feedbacks of any type, torque sensors, KTY / PT1000
  • Motor Brake control with power saving mode and special latching brake algorithm
  • Most comprehensive set of certified safety features and much more…

…PERFECT FOR INTEGRATION

A perfect fit for your robot actuator with zero mess cabling. With their circular shape and hollow shaft they are ideal for fully integrated hollow-shaft actuators that are mainly used in robot arms.

  • Two standard sizes for 20mm and 40mm hollow shaft designs 
  • Designed for direct motor mounting
  • Optimized thermal management for cool robot/machine body
  • Smart cable guiding for zero cable mess and high reliability
  • Precisely machined body for flexible integration

…a dual high resolution absolute encoder

For the first time in a standard servo drive: Servo drive and position encoders work as one! Circulo features up to two integrated absolute encoders with no extra cables and no inconvenient encoder calibration tools.

  • 2 x Magnetic Absolute Encoders (up to 20bit resolution)
  • Dual-loop configuration for motor and gear output feedback
  • Optional battery based multi-turn functionality
  • Very low profile <5mm for both encoders
  • Calibration and diagnostics GUI within servo commissioning software

…Safety first

Defining the future for true human-robot collaboration. 

The optional Safe Motion Module for Circulo allows for SIL3 PL e level safe motion functions over FSoE (FailSafe over EtherCAT). Implement your application according to ISO/TS 15066.
