Frequency Converter SD4S

The SD4S series is the successor to the proven SD2S variants. The SD4S devices are designed for stationary use in control cabinets of machine tools, turbo compressors and turbo blowers.

Highlights

  • PWM Frequencies up to 32 kHz

    Function:
    The SD4S provides PWM frequencies up to 32 kHz and commutation frequencies up to 64 kHz.

    Advantage:
    Higher rotating field frequencies up to 6,000 Hz and lower harmonic frequency components.

    Benefit:
    Realization of higher pole motor designs and lower motor losses.

  • Motor Analyzer

    Function:
    Simulation of the operating points and FFT analysis with THDi and THDu calculation.

    Advantage:
    Analysis of system performance already at the start of development.

    Benefit:
    Reduction of development time, costs and risk as well as optimization of the overall system.

  • Galvanically Isolated Thermal Contact Input

    Function:
    The input for the thermal contact is galvanically isolated from the logic and main voltage.

    Advantage:
    Safe operation even in case of an insulation problem of the thermal contact in the motor.

    Benefit:
    Protection of the inverter in the event of a fault and higher system availability.

Better Performance and New Control Functions

The first available unit type is designed for small high-speed spindles or motors in the power range from a few hundred watts to 1 kW. Application areas are e.g. dental milling machines or machines for super finishing as those required in watchmaking. Since small spindles do not come with a sufficient insulation resistance in the motors, SD4S now features a galvanic isolation of the thermal contact.

An absolute novelty is the design width of 40 mm only. Particularly in applications with many axes and a low performance, the demand for highly compact drive systems is great. Thus, the construction volume has been further reduced. The parameterization is realized via a default Ethernet interface that replaces the USB interface, which in industrial environments is prone to failure.

Moreover, SD4S comes with programmable digital measuring system interfaces such as Biss-C, EnDat2.2 and TTL. Via a Webserver, technicians can display device information without the need of additional parameterization software. Thanks to the real-time clock, a time synchronization of an incident is possible: Users can figure out whether a failure has been caused for example by a thunderstorm.

The optimized performance, higher speeds as well as the lower motor heating without sine-wave filter are substantial advantages of SD4S.

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.
