A FrequencyDriveAxisType is a DriveAxisType with a frequency command interface. Figure 20 shows a block diagram demonstrating the basic organization and control flow for this axis type. If the Drive is a PROFIdrive, the FrequencyDriveAxisType is used to represent AC1 Drive Objects using a frequency command interface.
