Virtual axes
Virtual axes are axes that do not exist physically. They are used, for example, to implement a master axis in the MOVI‑C® CONTROLLER. In "Tracking" mode, a virtual axis can be used, for example, to couple several axes and move them synchronously to one another.
The virtual axis is calculated in the MOVI‑C® CONTROLLER. This is the reason that virtual axes must be subordinate to a MOVI‑C® CONTROLLER.
INFORMATION
The sequence of initialization and retrievals of the devices in the programs INIT, MAIN and PRIORITY occurs in the sequence of devices below the MOVI‑C® CONTROLLER in the function view (from left to right) in MOVISUITE®. This is necessary so that in tracking mode, for example, the setpoints of the master axis (implemented as virtual axis) can be calculated before the position setpoints of the slaves. In MOVISUITE®, a virtual axis should therefore always be arranged to the left of the devices for which it acts as the master axis. For more information, refer to the "EtherCAT®/SBusPLUS Master" manual.
