P1-03
Feedback Device
Scaling
Sets the scaling of feedback device in user-
set units.
P1-04
Start / Draw Down
Level
The system starts when the feedback level
drops below the start level for the time set
in P1-05. This level also specifies the wake-
up level when the drive is in Sleep Mode.
When this parameter is set to a negative
value, the feedback level must drop that
amount below the setpoint.
Setting this parameter to 0.0 disables the
function. When P1-01, Pump Mode, is set
to 3 (MEMOBUS network), this function is
active only on the first drive in the network.
Note:
When PID operates in
reverse mode, the system
will start when the
feedback has risen above
the start level for the time
set to P1-05.
P1-05
Start Level Delay Time
The system starts when the feedback level
drops below the start level for the time set
in this parameter.
P1-06
Minimum Pump Speed
Minimum frequency at which the drive will
run. Applies to both HAND and Automatic
modes.
Note:
For minimum pump
frequency, the drive will
use the highest setting
from among P1-06, P4-12
(Thrust Bearing
Frequency), or d2-02
(Reference Lower Limit).
P1-07
Minimum Pump Speed
Units
0: Hz
1: RPM
Note:
Changing this parameter
will reset the P1-06 default
value.
P1-08
Low Feedback Level
Sets the lower detection level for the PID
feedback.
P1-09
Low Feedback Level
Fault Delay Time
Sets the amount of delay time from when
the low feedback is detected until the drive
faults on an “LFB Low Feedback” fault.
P1-10
Low Feedback
Selection
0: Fault
1: Alarm
2: Digital out only
P1-11
High Feedback Level
Sets the upper detection level for the PID
feedback.
P1-12
High Feedback Level
Fault Delay 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)).
P1-13

0: Fault
1: Alarm

Description
P1-14
Hysteresis Level
Sets the hysteresis level used for low and
high level feedback detection.
P1-15
Maximum Setpoint
Difference
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.
P1-16
Not Maintaining
Setpoint Time
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.

0: Fault

Prime Loss Detection
Method
0: Current (A)
1: Power (kW)
2: Torque (%)
P1-19
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.
P1-20
Loss of Prime 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.
P1-21
Loss of Prime
Frequency
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).
P1-22
Loss of Prime
Selection
0: Fault
1: Alarm
2: Digital out only
P1-23
Loss of Prime
Maximum Restart
Time after Fault
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.

display when P1-02 = 26.

P1-40
Maximum Pump
Speed
Sets the maximum pump speed.
This parameter does not affect operation
when set to 0.0 or when set to a value higher
than E1-04 x d2-01.
This parameter is internally lower limited to
the minimum pump speed (P1-06, P4-12,
d2-02) when not set to 0.0.
