Introduction vacon • 3 Synchronize positioning 1. Introduction Frequency converter works as a positioning controller with the help of encoder. Encoder should be installed on motor shaft but also it’s possible to use encoder after gear. When encoder is in motor shaft it’s possible to use closed loop motor control. This makes positioning more accurate. Application support also System Bus communication this communication makes possible to synchronization with two drives. Master drive sends it’s actual position to Follower drive and follower correct it’s speed reference to stay in position window if follower drive fails to stay in window follower sends stop request to master an both drive stops at the same time with minimum position difference.
