Frequency
FdbkLossGotoFreq
Sets the speed at which the drive will run if a 4 to 20 mA wire
break is detected on the PID Feedback and when b5-12 is set to
3 (Run at b5-13).
Default: 0.0 Hz

(01B2) Feedback Loss of Prime
Level
FdbkLoss LOP Lvl
Detects loss of prime in the pump when a wire break condition
has occurred.
When the measured quantity determined by P1-18 (output
current, kilowatts, or power) drops below this level for the time
set in P1-20 and the output frequency is at the level set in b5-13,
a “Loss of Prime” condition occurs.
The drive responds to the “Loss of Prime” condition depending
on the setting of P1-22, Loss of Prime Selection.
Default: 0.0 A

(01B3) Feedback Loss Go To
Frequency Time Out
FdbkLossGotoTimO
When b5-12 = 3 and the Feedback signal is lost, the drive will
run at the b5-13 speed for the b5-15 time, after which the drive
will fault on Feedback Loss (FDBKL).
Timeout is disabled when set to 0sec and the drive will run
indefinitely at b5-13.
Default: 0 s
Min.: 0
Max.: 6000

(01B4) Feedback Loss Start
Delay
FdbkLossStartDly
When an AUTO Run command is initiated, the drive will not
fault on Feedback Loss (FDBKL) or use the Feedback Loss
GoTo Frequency (b5-13) until the b5-16 time has expired.
Default: 0.0 s
Min.: 0.0
