<p>PURPOSE:To efficiently adjust set function values by displaying a settable range on a screen at the same time when the set function values are inputted. CONSTITUTION:When a function number is inputted by key operation to set the function of an inverter, a display unit 101 displays the inputted function number, its function name, a set current value, and the settable range of the set function value. The settable range may be displayed on a graph. Display control over the display is performed by input from an inverter operation command device 100 through the operation of a microprocessor according to a program stored in a storage element. Then when the key operation for varying the function set value is performed, the set value to be varied is displayed on the display screen of the display unit 10 together with the display of the settable range. Therefore, the input operation for the set value can be performed while the settable range which is displayed is referred to, so the need to store and investigate the settable range is eliminated.</p> |
