ABSTRACT:
An operation command process for selecting and setting operation commands, such as frequency and voltage, for operating an inverter to control an induction motor. Multiple operation commands are individually defined. Then, the multiple operation commands are stored as a group in memory. The defining of the operation commands and storing them as an operation command group is repeated, each group corresponding to different application and load conditions of the induction motor, so that a plurality of operation command groups are stored in memory. One of the groups is selected and read from memory, and then used to operate the inverter to control the induction motor.
