ABSTRACT:
A method for setting a plurality of operation constants in an inverter device to control variably the speed of an induction motor, the method which changes a value representing the operation constant on a display stepwise in one direction of increase and decrease due to an operation of at least one constant operation setting key. The method increases the stepwise change of the value gradually corresponding to a continuously increasing time of another setting key operation, and set the value on the display as an aimed value of the operation constant.
