Claims (1)
- 回転体主軸に連結される誘導電動機を駆動する電動機駆動装置において、
通常は、指令される前記主軸の速度指令値に対応しつつ、前記電動機のV/f制御に基づき該電動機に所望の交流電力を前記電動機駆動装置から供給することで、前記電動機を駆動し、
前記主軸の速度指令値に対応して前記電動機が回転中に、該主軸の位置決め指令が発せられたときには、
先ず、前記電動機のV/f制御に基づき該電動機を所定の減速勾配で零速まで減速し、その後、前記電動機のベクトル制御に切替え、停止位置と前記主軸の位置を示す位置信号との偏差に基づく位置指令用速度信号を生成し、この位置指令用速度信号によるベクトル制御を行って前記主軸の位置決め制御をすることを特徴とする電動機駆動装置の制御方法。
