The VelocityDriveAxisType is an DriveAxisType with a speed command interface. Figure 18 shows a block diagram demonstrating the basic organization and control flow for this axis type. If the Drive is a PROFIdrive the VelocityDriveAxisType is used to represent AC1 Drive Objects using a speed command interface.
