L5-41
(3671)
Hi Feedback Flt Retry
Selection
Sets the drive to do an Auto Restart when the drive detects an
HFB [High Feedback Sensed]
fault.
0
(0, 1)
0 : No Retry
1 : 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:
H3-xx = B: PID Feedback
L5-04: Interval Method Restart Time
Y1-11: High Feedback Level
Y1-12: High Feedback Lvl Fault Dly Time
Y1-14: Feedback Hysteresis Level
HFB Fault: High Feedback Sensed
