A controller outputting voltage instructions for drive control of an electric rotating machine adds, by using adders, position estimation voltage instructions for estimating the rotor position generated by a position estimation voltage generator, to drive voltage instructions, and outputs the resultant signals as voltage instructions. A position estimation device includes current extractors for extracting position estimation currents having the same frequency components as that of the position estimation voltage instructions, from electric rotating machine currents detected by a current detector, a position estimation current amplitude calculation section for calculating position estimation current amplitudes from the position estimation currents; and an estimation position calculation unit for calculating an estimated position of the electric rotating machine, based on the position estimation current amplitudes. The position estimation current amplitude calculation section calculates the position estimation current amplitudes, based on an autocorrelation obtained by squaring the position estimation currents.

An operation menu display control method for an analyzer is provided which can change the ranking of operation menus to be displayed preferentially in accordance with the frequency of their use by users and which can set operation menus that can be displayed preferentially regardless of the frequency of their use. A storage unit stores a usage count 23 of each of the used operation menus and a usage count ranking 24 with regard to each of the roles played by the users such as a system administrator 20 and an operator 21. Based on the roles of the users who use the analyzer, the method causes a display unit to display the highest-ranked “n” operation menus in terms of usage count stored with regard to each user. The operation menus to be displayed on a display means regardless of the frequency of their use are registered beforehand in a registered/unregistered region 25. The registered operation menus are displayed preferentially on a display device regardless of the frequency of their use.
