When P9-12 is set to 0, this parameter sets the level below which
the output frequency must fall for the time set in P9-15 before
the lead drive will send a request to be removed from the system
via the iQPump MEMOBUS network.
Remove Freq Lvl When P9-12 is set to 2 and the delta feedback (feedback minus
setpoint) has exceeded the level set in P9-14 for the time set in
P9-15, this parameter sets the level below which the output
frequency must fall before the lead drive will request to be
removed from the system via the iQPump MEMOBUS network.
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.
Sets the delay time before the lead drive is removed from the
system.
Remove Dly Time
Sets the time used top stabilize the system when a pump is staged
or de-staged.
Stabilize Time
Lead/lag control and pump protection are suspended during this
time.
Sets the value by which the system setpoint is incremented
depending on the number of pumps that are running.

Sets the feedback level that will trigger a quick de-stage. Set as
a percentage of the P1-09 value.
High FB De-stage 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.

Sets the lead drive selection priority overriding the P9-01
selection.
Run Priority
If multiple drives have the lowest P9-21 value, then P9-01
determines which drive becomes the lead.
Sets the number of times that the iQPump MEMOBUS network
will allow automatic restarts of system faults.
System Flt Retry 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.
Sets the maximum number of pumps that can run on the system. Default: 8
MaxPumps Running
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
Lead Swap @Sleep
drive available with a lower P9-21 setting.
Setting this parameter to 0 will disable the function.
