Frequency Converter FC2

Frequency Converter FC2

The FC2 offers the possibility to drive up to eight asynchronous high-speed spindles at the same time. The device topology with the controlled DC link and the PAM modulation allows to drive asynchronous motors up to a rotating field frequency of 8,333 Hz (500,000 rpm) without encoder and without motor chokes. The output voltage of max. 3 x 230 VAC is optimized for the high-speed spindles used in PCB drilling and milling. By means of parameter switching/spindle selection, the converter parameters are automatically adjusted depending on the selected spindles. In order to reduce the number of external components, the FC2 offers the possibility of evaluating up to eight speed and temperature sensors.

Highlights

  • Output Frequencies up to 8,333 Hz

    Function:
    Established PAM technology with optimized dynamic characteristics, efficiency and flexibility

    Advantage:
    Virtually no speed limitation combined with optimized control dynamics and excellent system efficiency

    Benefit:
    Low initial costs, possibility to access new applications

  • Multi-spindle operation of up to eight asynchronous spindles

    Function:
    Parallel operation of up to 8 asynchronous spindles and evaluation of speed encoders and temperature sensors

    Advantage:
    Only one frequency converter needed and no external components for evaluation

    Benefit:
    Cost and space savings, easy parameterization

  • No Need of Motor Chokes or LC-Filters

    Function:
    The PAM technology allows smallest switching frequencies and reduces the isolation stress of the motor as well as interferences (EMC) significantly.

    Advantage:
    Additional filter elements or motor chokes are not required.

    Benefit:
    Low system costs, easy initial operation.
