PROBLEM TO BE SOLVED: To provide a power control module which is small-sized, makes it possible to use an inverter and its controller under wide environments without a problem of dew condensation and so on, and to form easily a program for controlling the operation of a system containing rotating machines to be variable-speed-operated by power supplied by the inverter. SOLUTION: A power module 21 having power elements 23 of a converter section and power elements 24 of an inverter section constituting an inverter, an inverter control module 27 having a CPU element 28 for controlling the inverter, and a sequence control module 30 having a CPU element 31 for controlling the operation of a system to be operated by power supplied by the inverter, are provided. And the inverter control module 27 and the sequence control module 30 are connected electrically so as to give or receive signals mutually, and the sequence control module 30 is loaded with a system program and it is possible to form and change easily application programs which control system operation. |
