Drive control apparatus for electrical machine and parameter display method in drive control apparatus for electrical machine

摘要

A drive control apparatus for a driven machine (4) is designed to easily check which of a plurality of parameters indicating the control characteristics of the driven machine have been changed from their factory-set initial values. Initial parameter values are stored in a list in a first memory (701) and current parameter values are stored in a second memory (11). When a display request is given, the initial values of parameters stored in the first list in a control section are compared to the current values of the parameters stored in nonvolatile memory (11). The identity of the parameters that have been changed from their initial values are displayed on a liquid crystal display (1601). Also, the stored initial value list is displayed.
