Abstract
The rotor data including a model name, a maximum rotating speed, and a rotor identification number of a rotor that is purchased after installation, for example, is stored through the inputting unit in an EEPROM in addition to the rotor data that was stored in the ROM before shipping. The inputted rotor data is displayed on the display in a list image together with the rotor data of the rotor data in the ROM to provide easily selection of the rotor. The inputted rotor data may be displayed with priority to the rotor data in the ROM. The rotor data may further include check data. It may be judged that the inputted rotor data is correctly inputted. If the rotor data is incorrectly inputted, an error message is displayed and the rotary data is not stored. If the rotor data is correctly inputted, the rotary data is registered in the RAM.
