PURPOSE:To automatically set the output frequency of an inverter device in case of performing synchronized operation by equipping it with an inverter part, which converts DC input into AC and outputs it, and a control means, which controls the output frequency of the inverter. CONSTITUTION:First, by setting the input of a synchronized operation signal by a setter 16, the automatic calculation mode of output frequency fA is selected. Next, the acceleration and deceleration times in case of processing a work are set in inverter devices 2 and 3, respectively. Next, the certain constant velocity revolution No of the work is selected, and selected No is set in the inverter devices 2 and 3. Next, the calculation formula stored in ROM 30 is executed by CPU 17, and it performs the automatic calculation of the output frequency of fA of the inverter device 2. Furthermore, the output frequency fA is automatically set to an output frequency seller 26 by the command of CPU 17. Next, the output frequency fB of the inverter device 3 is automatically set. When the inverter devices 2 and 3 are controlled according to the above operation, two driving motors 4 and 5 becomes synchronized operation. |
