Integrated MotionRobot motion control for the future. SOMANET Circulo is the world’s first Integrated Motion Device: a complete servo solution for robots and smart actuators that features:
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.
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.
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.
SOMANET Circulo now comes with a BRAKE System preventing the motor from unwanted rotary motion.
The brake system’s latching solenoid is only activated when the motor drive is disabled, or in the event of an emergency stop.
This brake system, which acts as a holding brake, prevents any movement of the robot. This prevents unwanted contact with the workpiece to be machined, just like unwanted contact between robot and human.

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.
*Functions must be implemented inside safety controller using safe process data.
