P9-14
(0E01) Remove Delta Level Remove Delta Lvl
When P9-12 is set to 1, this parameter sets the level above which
the delta feedback (feedback minus setpoint) must rise for the
time set in P9-15 before the lead drive will request to be removed
from the system via the iQPump MEMOBUS network.
When P9-12 is set to 2 and the output frequency has exceeded
the level set in P9-13 for the time set in P9-15, this parameter
sets the level above which the delta feedback (feedback minus
setpoint) frequency must rise before the lead drive will request
to be removed from the system via the iQPump MEMOBUS
network.
Default: 0.0 PSI
<1>
Min.: 0.0
Max.: 6000.0

P9-15
(0E02) Remove Delay Time Remove Dly Time
Sets the delay time before the lead drive is removed from the
system.
Default: 10 s
Min.: 0
Max.: 3600
–
P9-16
(0E03) Stabilization Time Stabilize Time
Sets the time used top stabilize the system when a pump is staged
or de-staged.
Lead/lag control and pump protection are suspended during this
time.
Default: 3 s
Min.: 0
Max.: 3600

P9-17
(0E04) Setpoint Modifier Set-pt Modifier
Sets the value by which the system setpoint is incremented
depending on the number of pumps that are running.
Pump 1: Setpoint
Pump 2: Setpoint + ((X-1) (P9-17))
Default: 0.0 PSI
<1>
Min.: -999.9
Max.: 999.9

P9-18
(0E05) High Feedback Quick
De-Stage
High FB De-stage
Sets the feedback level that will trigger a quick de-stage. Set as
a percentage of the P1-09 value.
The quick de-stage ignores parameters P9-12 to P9-15 and uses
an internal 2 second delay.
Setting this parameter to 0.0 disables the feature.
Default: 97.0%
Min.: 0.0
Max.: 100.0

Default: 0
Range: 0, 1

(0E07) Allow Network Run
Allow Net Run
0: Always
1: First/Altrnation
2: First Only
3: Alternation Only
Specifies when a network Run command is allowed.

2: First only
3: Alternation only
Default: 0
Range: 0 to 3

P9-21
(0E08) Run Priority Run Priority
Sets the lead drive selection priority overriding the P9-01
selection.
If multiple drives have the lowest P9-21 value, then P9-01
determines which drive becomes the lead.
Default: 8
Min.: 1
Max.: 16
–
P9-22
(0E09) System Fault Retry System Flt Retry
Sets the number of times that the iQPump MEMOBUS network
will allow automatic restarts of system faults.
The drive uses L5-04, Fault Reset Interval Time, to determine
when to attempt a system fault restart.
Set this parameter to the same value for all drives on the network.
Default: 5
Min.: 0
Max.: 10
–
P9-23
(0E0A)
Maximum Number of
Running Pumps
MaxPumps Running
Sets the maximum number of pumps that can run on the system. Default: 8
Min.: 1
Max.: 8
–
P9-24
(0E0B) Lead Swap at Sleep Lead Swap @Sleep
Sets the length of time for which the lead drive will be in Sleep
Mode before this drive will request a swap when there is another
drive available with a lower P9-21 setting.
Setting this parameter to 0 will disable the function.
Default: 0 s
Min.: 0
Max.: 7200
–
P9-25
(0E0C) Highest Node Address Highest Node Adr
Sets the highest possible node address in the MEMOBUS
network.
For optimal network performance, set the serial communication
address H5-01 beginning with 01h consecutively up to the last
drive and then set this parameter to that H5-01 address.
Default: 8
Min.: 2
Max.: 8
–
P9-26
(0E0D) Master Time-out
Master Time-out
Sets the minimum amount of time that the slave drives will wait
for a message from the master before performing the action set
in P9-27.
Default: 4.0 s
Min.: 1.0
Max.: 10.0
