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
Posted 7 Nov 2023 Section 5.5 from here: https://dl.mitsubishielectric.com/dl/fa/document/manual/inv/ib0600503eng/ib0600503engm.pdf But a lot depends on the equipment you have available... What PLC? Is there positionnig card installed on the A840 and motor feedback (encoder)? Share this post Link to post Share on other sites
