This property enables or disables fast data information transfer. When axis fast data are enabled, axis status and feedback information is transferred to the host every SERCOS cycle.

Axis status and feedback information are available for the first 8 axes in the system. In a given system, only the data for the defined number of axes are available.

Two bytes are allocated for axis status information. The following status bits are returned. All unused bits return 0.
       ISSETTLED: set to 1 when the axis is settled
       ISMOVING: Set to 1 while the profiler is active
       DRIVEENABLED: set to 1 while the axis is enabled
       DRIVEFAULT: Set to 1 when a fault exists on the drive

Axis position and velocity feedback are returned. Each item is returned as a double precision floating point number (8 bytes) in user units.
