Hi Feedback Flt Retry
Selection
Sets the drive to do an Auto Restart when the drive detects an HFB [High Feedback Sensed] fault.

0 : No Retry

• When L5-41 = 1 and b5-09 = 0 [PID Output Level Selection = Normal Output (Direct Acting)] , the auto-restart
timer will not start timing until after the feedback level decreases to less than Y1-11 [High Feedback Level] (- Y1-14
[High Feedback Hysteresis Level] ).
• The drive will set the output frequency to zero during the auto-restart interval time.
• If you remove the Run (or HAND) Command during the auto-restart interval time, the drive will immediately detect
and reset the fault.
•
When L5-49 = 1 [Fault Retry Speed Search Select = Enabled] , the drive will do a speed search when it resets and
restarts after a fault.
• When you enable Thrust or Pre-Charge Modes, the drive will operate them correctly.
When L5-41 = 1 , the drive operation will change when b5-09 [PID Output Level Selection] changes:
