    1.1 MAIN FUNCTIONS

Function Description

    GA7200 can be operated easily with the Drive Mode digital operator.

    Function selection and constant setting for Program Mode GA7200 can be performed with the digital

    operator.

    Monitoring of output frequency, output

    current, output voltage or status of run / stop Monitor Function commands can be performed with the digital

    operator.

    If a fault occurs, its contents order of

    occurrence is displayed. When the power

    Fault Contents Display supply is turned ON, maintenance

    inspection or troubleshooting can be

    performed since fault is recorded.
