4.6 Basic iQpump Setup and Application Preset Parameters
n P3-70: Pump 4 Frequency Shutdown Level
Sets the level at which the third lag pump (4th pump in the system) will shut down or de-stage. This parameter is effective
when the P3-01 is set to 0 or 2 (pump staging is based on output frequency). When the output frequency falls below the P3-50
leel for the time set in P3-09, the pump will be de-staged.
No.
P3-40
n P4-01: Pre-Charge Level
Sets the level at which the drive will activate the pre-charge function. At start, if the PID is below the P4-01 setting, the drive
will run at the P4-02 frequency setting for the time set in P4-03. PID control is delayed until the Pre-charge function stops.
The drive will exit the pre-charge function early if the feedback rises above the P4-01 setting or if a Low Water digital input
switch (H1-oo = 8F) deactivates. Pre-charge is useful to slowly fill or pressurize a system.
No.
P4-01
n P4-02: Pre-Charge Frequency
Sets the frequency at which the pre-charge function will run.
No.
P4-02
n P4-03: Pre-Charge Time
Sets the duration of time that the Pre-Charge function will run.
No.
P4-03
n P4-10: AUTO Mode Operator Run Power Down Storage
Selects drive response to power loss with regards to the Run command. When running in AUTO Mode and using a Run
command from the keypad (b1-02 = 0), P4-10 determines whether the drive will automatically start running when power is
reapplied. The factory setting of this parameter requires pressing the AUTO key to start the drive after power loss.
WARNING! Sudden Movement Hazard. If the drive is running at power loss, it will automatically initiate an internal Run command upon
power-up if P4-10 = 1 (Enabled) and could result in death or serious injury from moving equipment.
No.
P4-10 AUTO Mode Operator Run Power Down Storage
Setting 0: Disabled
Setting 1: Enabled
n P4-12: Thrust Bearing Frequency
Sets the frequency used by the drive when determining which acceleration and deceleration time to use. The Thrust Bearing
function is used for applications using submersible motors. The function provides an alternate acceleration time (P4-11) and
deceleration time (P4-13) for protecting the pump bearings.
At start, the drive will use the P4-11 acceleration time until the P4-12 frequency is reached, at which time it will use the active
C1-oo acceleration and deceleration times. At stop, if the output frequency is above the P4-12 setting, the active C1-oo
deceleration time will be used until the P4-12 setting is reached at which time it will use the P4-13 time setting for the rest of
deceleration.
If P4-12 is set greater than P1-06 (minimum Pump Speed), P4-12 will become the frequency lower limit. The drive PID control
must be disabled (b5-01 = 0) for this function to work.
No.
P4-12
n P4-17: Utility Start Delay
Set the delay time after power up until the drive will recognize a Run command present within one second of power up.
