Zusammenfassung:	Systems and methods are disclosed for controlling the rotation of turrets with servo motors within a machine line used in the shaping of articles. Error conditions can be detected using the servo motors for resolving issues with the machine line. Control of the turrets by the servo motors allows for each turret to be rotated relative to the other turrets independently for resolving the issues. Absolute encoders are used to return the servo motors and their respective turrets back to being aligned with a virtual axis for synchronous rotation of the turrets within the machine line, despite the turrets not being mechanically coupled together by a series of gears.
