0 : Disabled
1 : Alarm Only
2 : Fault
Note:
When
b5-82 = 2
, PID feedback detection will trigger an alarm if one of these conditions is true:
•
The drive is in HAND Mode
•
The drive is not in AUTO Mode
3 : Run At b5-83
If the drive detects a Wire-Break, the drive will respond as specified by
b5-82
.
Note:
•
A: The keypad shows an
FDBKL [Feedback Loss Wire Break]
alarm.
•
F: The drive detects an
FDBKL [WIRE Break]
fault.
•
R: The drive operates at
b5-83 [Feedback Loss GoTo Frequency]
and shows an
FDBKL
alarm.

*1
The keypad will show the
FLGT [Feedback Loss, Go To Freq b5-83]
alarm. The drive will run at
b5-83
after Utility Delay is expired.
*2
The drive will operate at
Y4-02 [Pre-Charge Frequency]
while Pre-Charge is active.
Note:
•
If the drive is set in a mode where the fault will occur, the drive will detect the fault only when the drive is in operation. If the drive is not in
operation, the drive will detect an alarm. Refer to
for an example where
b5-82 = 2 [Fault]
and the drive is OFF.
•
If the Feedback Loss fault is set to
L5-42 = 1 [Feedback Loss Fault Retry Select = Retry]
, the drive will use the
L5-04 [Interval Method
Restart Time]
timer when it Auto-Restarts.
PID Feedback Loss Detection Start Delay
You can use
b5-86 [Feedback Loss Start Delay]
to delay the PID Feedback Loss Detection at start. Feedback Loss
detection will still be active when
b5-86
timer has started, but the drive will only detect an alarm. When
b5-86
expires, the drive will use the
b5-82
setting to start the appropriate action. Refer to
for more information.
b5-86: Feedback Loss Start Delay
H2-xx = B9: Transducer Loss
H3-xx = B: PID Feedback
FDBKL Alarm: Feedback Loss Wire Break
FDBKL Fault: WIRE Break
