PURPOSE:To set, alter the various functional data of an inverter from a programmable controller by incorporating the controller, a memory cell and a CPU in the inverter, inputting an operation signal and the data distinctly to the CPU and controlling it. CONSTITUTION:A programmable controller 1 is continued in an inverter 7, and the controller 1 is connected directly to a CPU 5 to directly apply normal and reverse rotation signals 13, 14. A memory cell 11 is provided between the controller 1 and the CPU 5, functional data 12 such as acceleration/deceleration times, etc., output from the controller 1 are temporarily stored in the cell 11 and applied to the CPU 5. Thus, an operation command is most preferentially received from the controller 1 connected directly thereto to the CPU 5 in a very short period of time, and the functional data of the inverter 7 can be set, altered through the controller 1. |
