P1-11
(0C0A) High Feedback Level
High FB Level
Sets the upper detection level for the PID feedback.
Default: 155.0
PSI
Min.: 0.0
Max.: 999.9
P1-12
(0C0B) High Feedback Level
Fault Delay Time
High Lvl FLT Time
Sets the amount of delay time from when the high feedback is
detected until the drive faults on a “HFB High Feedback” fault.
Note:
This parameter is effective only when P1-13 is set
to 0 (Fault (and digital out)).
Default: 5 s
Min.: 0
Max.: 3600
P1-13
(0C0C)
High Feedback
Selection
High FB Sel
0: Fault
1: Alarm
2: Digital Output
Selects drive response during the “High Feedback” condition.
0: Fault
1: Alarm
2: Digital out only
Default: 0
Range: 0 to 2
P1-14
(0C0D) Hysteresis Level
Hysteresis Level
Sets the hysteresis level used for low and high level feedback
detection.
Min.: 0.0
Max.: 100.0
–
P1-15
(0C0E) Maximum Setpoint
Difference
Max Set Pnt Diff
Sets the level that the difference between the setpoint and the
feedback must exceed for the time set in P1-16 to trigger the
drive response set in P1-17.
If P1-17 is set to 1 (Fault and digital out), the will coast to stop.
This function is active when the drive is running during AUTO
Mode.
Setting this parameter to 0.0 disables the function.
Min.: 0.0
Max.: 6000.0

P1-16
(0C0F) Not Maintaining
Setpoint Time
Not Maint SP Tm
Sets the delay time before a “Setpoint Not Met” condition
occurs. The pump protection criteria set in P1-15 must be met
before the timer will start.
Setting P1-15 to 0.0 disables this function.
Default: 60 s
Min.: 0
Max.: 3600

Setpoint Selection
Not Maint SP Sel
0: Fault
1: Alarm
2: Digital Output
Selects the drive response method during the “Not Maintaining
Setpoint” condition.
0: Fault
1: Alarm
2: Digital out only
Default: 0
Range: 0 to 2

P1-18
(0C11)
Prime Loss Detection
Method
Prime Loss Mthd
0: Current (A)
1: Power (kW)
2: Torque (%)
Determines the quantity used to determine loss of prime.
0: Current (A)
1: Power (kW)
2: Torque (%)
Default: 0
Range: 0 to 2
–
P1-19
(0C12) Prime Loss Level
Prime Loss Level
Detects loss of prime in the pump when in Auto or Sleep Boost
Mode.
When the measured quantity determined by P1-18 drops below
this level for the time set in P1-20 and the output frequency is
above the level set in P1–21, 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
Min.: 0.0
Max.: 1000.0
–
P1-20
(0C13) Loss of Prime Time
Prime Loss Time
Sets the delay time before a “Loss of Prime” condition occurs.
The pump protection criteria set in P1-18 and P1-19 must be met
before the timer will start.
Default: 20 s
Min.: 0
Max.: 600
–
P1-21
(0C14)
Loss of Prime
Frequency
Prime Loss Freq
Sets the frequency level above which the “Loss of Prime”
detection is enabled when set to a value other than 0.
When set to 0 (default), the frequency level is determined by the
smaller value between (Fmax - 1 Hz) and (d2-01 - 1 Hz).
Default: 0.0 Hz
Min.: 0.0
Max.: [E1-04]
–
P1-22
(0C15) Loss of Prime Selection
Prime Loss Sel
0: Fault
1: Alarm
2: Digital Output
Sets the drive response method during the “Loss of Prime”
condition.
0: Fault
1: Alarm
2: Digital out only
Default: 0
Range: 0 to 2
–
P1-23
(0C16)
Loss of Prime
Maximum Restart Time
after Fault
LOP Max Rstrt T
Sets the time in minutes that the drive will wait before
attempting another restart when the restart fails or is not
attempted due to a continuing fault condition.
Default: 0.2 min
Min.: 0.2
Max.: 6000.0
–
P1-24
(0C17) Level at Full Speed
Level @ Full Spd
When set greater than 0, this level is used to override the P-gain
and I-limit with a calculated value based on Sleep level, Wake-
up level, Minimum Pump Speed, Transducer Scaling, and
Maximum Frequency.
This feature is disabled when set to 0.
Default: 0.0
Min.: 0.0
Max.: 6000.0
