Frequency Converter SD2S

Powerful, flexible and compact – these words describe the drive amplifier SD2S by SIEB & MEYER. Using the available drive functions synchronous and asynchronous motors with speeds up to 480,000 rpm can be driven by SD2S, especially in respect of a low motor heating in high-turning motors with small rotor volume. Furthermore, small motor temperatures are the basis for a high machining quality.

The Specialist for High-speed Applications

Depending on the application, the operation can be carried out with or without encoder. For the operation with an encoder SD2S offers the possibility to evaluate the common encoder systems existing on the market.

SD2S is connected to the higher-ranking control via analog reference values (+/-10 V), digital I/Os, RS232, USB, CAN bus, PROFIBUS*, PROFINET* or EtherCAT (CoE)**.

**CoE=CAN over EtherCAT

Easy but Robust

Additionally to the basic characteristics in respect of a low motor heating SD2S offers two drive functions characterized by an easy parameterization and a robust operation for applications up to 120,000 rpm. For asynchronous motors the drive function V/f-PWM is used. By means of the V/f characteristic curve the user can carry out the graphically aided parameterization of the motor. As using the V/f characteristic curve is an established form of motor parameterization for example in grinding applications, the user can take advantage of the experience gained in this field.

The SVC drive function (Sensorless Vector Control) is provided for synchronous motors and is based on the equivalent circuit diagram usually found in the motor data sheet. SVC allows 4-quadrant operation of high speed synchronous motors and generators so that SD2S can be used for high speed applications such as turbo blowers or turbines for utilization of process energy.

Technology Functions for Grinding Applications

Multi parameter sets

The flexibility of grinding machines largely depends on the possibility of a fast and simple use of grinding spindles. The feature of saving up to 64 motor parameter sets in the drives enables the variable operation with different motors. The number of parameter sets can be encoded via the digital inputs or alternatively via the provided data interfaces.

Gap eliminator / Load indicator

The load indicator is a standard function that is implemented in all devices of series SD2x. The function is used to monitor the status of the active current of spindles. If a preset motor workload is exceeded, the function generates a message. In contrast to acoustic emission sensors, this function evaluates the actual active current of the motor. This is why a very high precision is possible when detecting the load changes of the motor. A load created by e.g. a touch between tool and work piece causes a significant rise in the motor current. Such a load is detected by means of the load indicator. This makes additional external components obsolete.

The load indicator can be used:

  • as an indicator for tool breakage
  • as a main system in dressing processes
  • for a detection with micrometer precision when the tool touches the work piece (gap / touch)
  • as an indicator for a necessary tool change due to abrasive wear
  • as an indicator for a necessary feed rate reduction (productivity increase by reducing the air-cutting time)
  • for a fully automatic adjustment
  • as a substitute for acoustic sensor technologies (acoustic emission)

Software for Initial Operation and Parameterization: drivemaster2

The oscilloscope function allows optimization of the axes in the machine via the drive-setup-tool without additional measuring equipment.

The clear design of the software allows intuitive parameterization via graphics and block diagrams. The „Parameter-Wizard“ guides the user step-by-step through the system configuration and allows intuitive setup of the device via help messages and comments.

  • 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.

  • 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.
