P1-11
(0C0A) High Feedback Level High FB Level
Sets the upper detection level for the PID feedback.
Note: When P1-03 is set to 3, parameter P9-18 uses the
value set here to calculate quick de-stage
feedback level.
Default: 155.0

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

P1-15
(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 drive will coast to
stop.
This function is active when the drive is running during AUTO
Mode. When P1-01 is set to 3 (MEMOBUS network), the
function is active on the lead drive and will stop all drives
running on the network when the NMS fault occurs.
Setting this parameter to 0.0 disables the function.
Default: 0.0 PSI

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

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

(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]

attempted due to a continuing fault condition.
