Posted 7 Nov 2023 Hello Guys. Is it possible to use an fr-a840 to use in the same time positioning control and also in speed control mode ? In the moment the vfd is in speed control mode. But now i also have to need to stop the conveyor in certain position. It will be a new feature. If its not possible, do i need a hsc ? The speed of the conveyor is 20 m/min and the accuracy should be within 3 mm. Could anybody help me with this. Thanks ahead. Share this post Link to post Share on other sites
