PURPOSE:To make the operation of an inverter drive simple and precise, by indicating selectively the various informations relative to the operation of the inverter drive in the indicator of the operating device therefor. CONSTITUTION:When the alteration of the setting of the acceleration time of an inverter drive is performed as a functional exmple, if the acceleration time is selected by a PRG key, then, in an indicator 3, the acceleration time to be a selected function and its present value of 6.0s are indicated as shown in the left figure of the figure 1. Subsequently, when the set value of the acceleration time is altered into 6. 1s by a set-value increasing key having a mark LAMBDA, its altered value of 6.1s is indicated in the indicator 3 as shown in the right figure of the figure 1, and in relation to this, its present value of 6.0s and its maximum value of MAX360s are indicated concurrently. Reversely, when the set value of the acceleration time is altered into 5.9s by a set-value decreasing key having a mark V, its altered value of 5.9s is indicated in the indicator 3 as shown in the right figure of the figure 1, and in relation to this, its present value of 6.0s and its minimum value of MIN0. 1s are indicated concurrently. |
