PURPOSE:To easily and precisely set plural operation constants which differ in setting range respectively at proper time in the inverter device which controls an induction motor. CONSTITUTION:This method is for setting the operation constants of the inverter device which variable speed control over the induction motor with setting keys other than a ten-key and the set value increase up key 2, decrease down key 4, and fast-forwarding key 3 of the console panel of the inverter device are used in combination to sets the necessary constants through the data display part 1 on the panel; and the increase or decrease direction is specified with the up key 2 or down key 4 and the quantity of variation in set value which increases or decreases stepwise at specific intervals of time is increased at a specific ratio as the continuous operation time of the fast forwarding key 3 increases or the time required for the stepwise variation in set value unit quantity in the individual continuous operation of the up key 2 or down key 4 is shortened at a specific ratio as the time of the continuous operation increases. |
