Description
If FB1.SELECT is set to -1, AKD automatically detects the feedback device. When auto-detection is successful, the identified feedback type is stored in FB1.LASTIDENTIFIED. On the next feedback initialization, the auto-detection algorithm will first look for the last identified type, speeding up feedback initialization and shortening drive boot time.
The time to automatically identify the device is shortened when FB1.LASTIDENTIFIED is already set to the correct feedback type.
Note that this parameter must be saved to non-volatile memory with DRV.NVSAVE in order to take effect each time the drive powers up.
