Servo Amplifier SD2S

Servo Amplifier SD2S

Powerful, flexible, low cost – these words describe the servo amplifier SD2S by SIEB & MEYER. The compact dimensions allow space-saving design of the switch cabinet. Linear motors, rotary servo motors, high-pole torque motors as well as synchronous/asynchronous tool spindles with or without sensor can be driven by SD2S.

For the connection to a higher-ranking control analog reference values (+/-10 V) or pulse-direction values, CAN bus or PROFIBUS* signals and protocols are processed. Alternatively, a CNC control can be connected via the bus system SERVOLINK 4. The communication via EtherCAT (CoE)** is optinally provided

* Via gateway
** CoE = CAN over EtherCAT

The Smart Drive Amplifier for Servo Applications

Universal Motor Encoder Interface

SD2S evaluates all common measuring systems for rotary and linear motors. The drive controls systems with absolute value encoders with EnDat, Hiperface or SSI interface, encoders, magnetoresistive sensors, Hall effect sensors, linear Hall sensors, linear scales with 1Vpp or TTL level as well as resolvers.

Safety Integrated

The currently effective safety category 4 can be reached by the integrated restart lock. As external protective circuits can be reduced, system costs are minimized.

Applications

  • High-speed spindles are the key components of a machine tool. Only when operated in an optimal way, the desired machining accuracy, productivity and service life of the whole machine is guaranteed. 

     

    Drilling, Routing

  • Grinding applications have a special position in the field of machine tools. Internal grinding applications, for example, require sensorless operation of asynchronous and synchronous spindles up to 250,000 rpm. 

     

    Grinding

  • For dressing applications, it is essential to keep the spindle temperature low: a temperature increase in the spindle causes a longitudinal growth and therefore a shift of the tool position. 

     

    Dressing

  • Small CAD/CAM routing machines are used, for example, in dental laboratories for jewelry making or engraving works as well as for producing advertising displays. 

     

    Dental CAD/CAM

  • High-speed dicing spindles are the key components in machines for microchip separation – the so-called wafer dicing. 

     

    Wafer Dicing

  • In the field of turbomachines, the system's efficiency can be continuously improved by increasing the system speed or omitting the gear. 

     

    Compressed Air Production

  • Due to their design, a large number of technologies in the field of waste energy usage or mechanical energy storage require high-speed motors and generators

     

    Wastewater Treatment

  • Rotary atomization processes, e.g. applied for the production of milk powder or flue gas treatment, require high circumferential speeds. Therefore, it is necessary to use matching high-speed motors instead of low-speed standard motors.

     

    Atomizer

  • Refrigeration units with turbo or centrifugal compressors with higher power ranges operate with high speeds. Frequency converters by SIEB & MEYER easily provide the required speeds and their control method ensures an exceptionally low rotor heating.

     

    Refrigeration and Air Conditioning

  • Polygon scanners are based on special optics and operate, for example, sorting machines. Up to now, manufacturers had to install encoders to run these scanners with a high speed stability.

    Polygon Scanners

  • Precision is indispensable for tightening applications: If the screw is required to be tightened with a defined torque, the servo amplifier must meet this requirement. 

    Tightening/Pressing/Clinching

  • PCB routing is determined by the continuously increasing technical and commercial requirements of the electronics industry. The steadily rising level of integration of the electronic components requires increasingly complex and more precise contours for PCBs.

    PCB Routing

  • PCB scoring is determined by the continuously increasing technical and commercial requirements of the electronics industry. The prevailing pricing pressure on electronic devices demands a step-up in productivity by means of an increasing machine automation.
