PROBLEM TO BE SOLVED: To solve the problem where noise due to belt drive is large and efficiency is low due to the generation of energy loss when operating a plurality of drive devices in synchronization using a timing belt, and software control for deceleration control in instantaneous stop is required and configuration becomes complex since each drive motor is controlled by an inverter constantly (including instantaneous stop) in a configuration where each drive device is operated in synchronization by the control of each inverter while a plurality of inverters are connected to one inverter. SOLUTION: In the system with a plurality of drive devices requiring synchronous operation, a plurality of induction synchronous motors 11 are connected in parallel with one inverter 10, the drive devices are operated in synchronization by each of the induction synchronous motor 11, and the output of the inverter 10 is stopped based on instantaneous stop detection. Also, the detection of instantaneous stop is detected at the input side of a converter 8. |
