*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
• 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
b5-86:
H2-xx = B9:
H3-xx = B:
Figure 2.29 Time Chart for the Wire Break Detection when b5-82 = 2 [Fault]
PID Feedback Loss Go To Frequency Timeout
The drive will apply this feature only when b5-82 = 3 [Run At b5-83] and it detects a Feedback Loss. Parameter b5-
85 [Feedback Loss GoTo Freq Timeout] sets the length of time that the drive will run at the frequency set in b5-83
[Feedback Loss GoTo Frequency].
• When b5-85 = 0 sec, the drive will operate at the b5-83 speed indefinitely.
• When b5-85 > 0 sec, the drive will only operate at the b5-83 speed for the time specified in b5-85, after which the
drive will fault on an FDBKL [WIRE Break] fault.
