INVERTER CONTROL DEVICE AND PERIPHERAL DEVICE THEREOF

摘要

Provided is an inverter control device capable of high-speed application of results of computation for a PLC portion to the operation control of an inverter without use of a high-end CPU. A drive control means 1 operates an inverter on the basis of input data and the operation state of the inverter. A computation means 6 carries out computation using the externally input data through an external input means 2, data output from the drive control means 1, data stored in a parameter means 4 or data output from a communication means 5, and supplies the results of the computation to the drive control means 1. In the inverter device 9, the processor that acts as the drive control means 1 is synchronized with a processing cycle corresponding to the control cycle of the drive control means 1 and carries out the computations of the computation means 6.
