INTEGRATED BRAKE SYSTEM

Integrated brake system (optional) with safe brake control

SERVO DRIVE

High-performance servo drive with maximum motion control performance

ULTRA COMPACT
This saves on components, interfaces and development work, and shortens assembly time.

RELIABLE
Highly efficient software algorithms compensate for electromechanical inadequacies and ensure the highest level of motion performance.

EFFICIENT
Costs are reduced by more than 50 % thanks to massive component savings. User-friendly and intuitive software simplifies processes.

FULLY EQUIPPED SERVO DRIVE

Are you planning a lightweight robot, a collaborative robot arm or an AGV / AMR application? Take advantage of Synapticon's advanced motion control technology and produce better products in less time thanks to the compact and efficient decentralized servo drives.

• Works with any PMSM/BLDC motor up to 60 V and 60 arms

• Maximum bandwidth, model predictive field-oriented control for high efficiency

• Dual-loop control, high-frequency control loops, gain scheduling

• Support for 2 position feedback signals of any type, torque sensors, KTY/PT1000

DUAL HIGH RESOLUTION ABSOLUTE ENCODER

The SOMANET Circulo combines a servo drive and position encoder in one standard servo drive for the first time.

Circulo has up to two integrated absolute encoders without additional cables and without the need for cumbersome tools for encoder calibration.

• 2 x magnetic absolute encoders (up to 20 bit resolution)

• Dual-loop configuration for motor and gearbox output feedback

• Optional battery-powered multi-turn functionality

• Calibration and diagnostics GUI in the commissioning tool

• Very low profile, less than 5 mm for both encoders

INTEGRATED BRAKE SYSTEM

SOMANET Circulo is equipped with an Integrated Brake System that protects the motor from unintentional rotational movements. This makes it ideal for motion control systems such as robot arms and mobile robots. The integrated brake system is ultra-compact, reliable and safe. 

SMALLER

60 - 90 % space saving

LIGHTER

50 - 90 % reduction in weight

MORE ECONOMICAL

65 - 90 % less power consumption (3 W)

• The motor speed is reduced to a low level before the brake engages.

• The brake prevents the motor from rotating unintentionally (e.g., in the event of a power failure).

• In this way, the servo drive prevents unwanted contact with the workpiece being processed or between the robot and human.

THE FUTURE OF TRUE HUMAN-ROBOT COLLABORATION

• STO - Safe Torque Off
  STO prevents the trolley from restarting unplanned. STO enables safe working and has a wide range of applications with moving axes.
  
  
• SBC - Safe Brake Control
  SBC enables the safe activation of a holding brake. The function is always activated in parallel with STO and used with STO or SS1. This prevents the movement of an axis in a torque-free state.
  
  
• SBT* - Safe Brake Test*
  
  
• SS1 - Safe Stop 1
  The SS1 function causes the motor to stop quickly and safely, and brings it to a standstill.
  
  
• SS2 - Safe Stop 2
  The SS2 function switches a motor off quickly and safely. If the motor comes to a standstill, a safe operating stop (SOS) is triggered.
  
  
• SLS - Safely Limited Speed
  SLS ensures that the drive does not exceed a defined speed limit and triggers an error response if this is exceeded.

• SLP - Safely Limited Position*
  The safety function monitors that the drive (and thus the element moved by the drive) does not exceed defined end positions.
  
  
• SLT - Safely Limited Torque*
  Safely limited torque. The SLT function enables the torque to be reduced within a defined time; if the torque exceeds the SLT monitoring limit, the drive reacts with a "safe stop".
  
  
• Safe Velocity Process Data
  via FSoE (7 ms cycle time)
  
  
• Safe Position Process Data
  via FSoE (7 ms cycle time)
  
  
• Safe Torque Process Data
  via FSoE (7 ms cycle time) - when connecting a safe torque sensor to the safe analog input.
  
  
• Safe digital IO and safe analog input
  via FSoE (7 ms cycle time)

SAFETY FIRST

The optional Safe Motion module for Circulo enables safe motion functions at SIL3, PL-e level via FSoE (FailSafe over EtherCAT). Realize your application in accordance with ISO/TS 15066.
