The Beckhoff AX2000 and AX2500 drive is available with different (in the case of AX2000 optional) fieldbus interfaces. The following dialogs are for an AX2000 with Beckhoff Lightbus interface (e.g. part no.: AX2003-B200). Nevertheless, the dialogs and descriptions is also suitable for AX2500, since these drives are fully software compatible to the AX2000.
