Abstract
An inverter apparatus is incorporated with a built-in programmable logic-controller (PLC). The PLC includes internal memory for directly outputting control signal to provide inverter operation control without time delay and noise. The inverter apparatus includes external terminals for function assignment and an external program can be coded for expanding the function of the inverter apparatus through the external terminals. The inverter apparatus of the present invention can overcome the problems of limited function and complicated wiring.
