Display
The drive will display a "High Feedback Level (HFB)" alarm when the
feedback level rises above the programmed level. The alarm will turn off
when the feedback level falls below the programmed High Feedback Level
minus the Hysteresis Level (P1-13). This function is active during running
in the hand mode, auto mode, pre-charge and thrust-bearing mode.
If P1-01 = 3, parameter P9-18 uses this value to calculate the quick de-
stage feedback level.
The drive will initiate a "High Feedback Fault (HFB)" when the feedback
level rises above the programmed level for a time specified in P1-10. The
drive will coast to a stop when a fault occurs. This function is active during
running in all operation modes.
If P1-01 = 3, the function will stop all drives running on the network when
the system fault occurs.
When the drive is running and the difference between the setpoint and the
feedback exceeds the level in P1-11 for the time specified in P1-12, the
drive will trip on a "Not Maintaining Set-point (NMS)". The drive will
coast to a stop when a fault occurs. A value of 0 disables this function. This
function is only active during running while operating in auto mode.
If P1-01 = 3, the function is active on the lead drive, but will stop all drives
running on the network when the system fault occurs.
Delay time before a Not Maintaining Set-point fault occurs. Pump
protection criteria specified in P1-11 must be met for the drive to fault. The
drive will coast to a stop when a fault occurs. A value of 0 disables Not
Maintaining Set-point fault.
Hysteresis Level used for low and high feedback alarm detection. See
function P1-07 and P1-09.
Used to detect loss of prime in the pump. If output current drops below this
level for the time specified in P1-12 and the output frequency is at fmax, a
"Loss Of Prime" fault occurs. The drive will coast to a stop when a fault
occurs.
If P1-01 = 3, the function is active on the lead drive, but will stop all drives
running on the network when the system fault occurs.

be programmed. The low water input can be used for a low water condition
or in combination with the pre-charge function to indicate the reservoir is
filled. The low water input fault is only active during running while
operating in auto mode.
Delay time before a Loss of Prime fault occurs. Pump protection criteria
specified P1-14 must be met for the drive to fault. On fault the drive will
coast to a stop.
