The use of the 5-motion Plus interface is only possible with a corresponding aggregate, which has an additional swivel mechanism. It can be controlled by the drive of the c-axis. Optionally, the interface can either assign the drive of the c-axis or the additional tilting axis. The change and adjustment is only possible between the single program steps. Hence the fifth axis is a positioning axis and thus can't be used interpolating.
In contrast to the standard-5-motion-interface the 5-motion plus interface has an own tool changing system. In this way the aggregate can be changed even via a HSK-F63 interface, additionally the tools used with the aggregate can be changed by a smaller interface, too. Because the interfaces are different, a separate tool changer is required.
