L5-40
(3670)
Low Feedback Flt Retry
Selection
Sets the drive to do an Auto Restart when the drive detects an LFB [Low Feedback Sensed] fault. 0
(0, 1)
0 : No Retry
1 : Retry
• When L5-40 = 1 and b5-09 = 1 [PID Output Level Selection = Reverse Output (Reverse Acting)], the auto-restart
timer will not start timing until after the feedback level increases to more than Y1-08 [Low 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 L5-40 = 1, the drive operation will change when b5-09 [PID Output Level Selection] changes:
H3-xx = B: PID Feedback
L5-04: Interval Method Restart Time
Y1-08: Low Feedback Level
Y1-09: Low Feedback Lvl Fault Dly Time
Y1-14: Feedback Hysteresis Level
LFB Fault: Low Feedback Sensed
