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).

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.
