인버터 제어 장치는, 인버터 제어 장치의 외측으로부터 반복하여 송신되는 지령 회전 속도를 취득하도록 구성되는 취득부와, 지령 취득 간격을 카운트하도록 구성되는 카운트부와, 상기 취득부에 의해 상기 지령 회전 속도가 취득된 것에 기초하여, 전동 모터의 목표 가속도를 설정하도록 구성되는 가속도 설정부와, 상기 목표 가속도로 상기 전동 모터가 회전하도록 인버터 회로를 제어하도록 구성되는 구동 제어부를 구비한다. 상기 가속도 설정부는 산출부를 갖는다. 상기 산출부는, 상기 지령 취득 간격과 신지령 회전 속도에 기초하여, 상기 목표 가속도로서 설정되는 지령 가속도를 산출하도록 구성된다.

    An inverter controller includes a processing circuitry. The processing circuitry is configured to obtain a command rotation speed transmitted repeatedly from outside of the inverter controller, count a command obtaining interval that is a period from a point in time where an old command rotation speed was obtained to a point in time where a new command rotation speed is obtained, set a target acceleration of the electric motor when the command rotation speed has been obtained, and control the inverter circuit such that the electric motor rotates at the set target acceleration. The processing circuitry is configured to calculate a command acceleration based on the counted command obtaining interval and the new command rotation speed, the command acceleration being set as the target acceleration.
