    Problem with Polar 78 XT
    Backgauge is not moving and displays Frequency Conv. Signal error and Error Code no 811. All other functions are ok.

    Hi Linus

    Please read this:-

    Error No.: 811
    Error Text: FREQUENCY CONV. SIGNALS ERROR
    State: ERROR
    Cause: This is a signal generated by the frequency converter, which is issued in case of an
    internal error detection of the frequency converter. It is a collective information on
    malfunctions in the frequency converter and backgauge motor.
    Remedy: - Check backgauge motor
    - Check drive mechanism, spindle and sledge guide for stiffness
    - Replace board SAP
    - Check setting of frequency converter
    - Check cabling / plug-in connections
    - Check frequency converter
