YASKAWA TOEP YAIP1W 02E YASKAWA AC Drive - iQpump1000 Installation & Start-up Guide
Description
Detects loss of prime in the pump.
When the measured quantity determined by
P1-18 drops below this level for the time set
in P1-20 and the output frequency is at the
level set in P4-06, 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.
0 : Disabled
1: Enabled
Sets the time at which the drive output
frequency will ramp up to the reference
frequency set in P4-12.
The drive will accelerate to this frequency
in the time set to P4-11. The drive will
decelerate from the frequency in the time set
to P4-13.
WARNING! Sudden Movement
Hazard. If the drive is powered down
while running, it will automatically
initiate an internal Run command
upon power-up.
Sets the amount of time it takes to bring the
drive from the Thrust Frequency set in
P4-12 to stop when Thrust Mode is active.
When the Run command is removed while
the drive is operating in Thrust Mode above
the Thrust Frequency, the time set in this
parameter is used when the frequency
reference is at or below the thrust
frequency.
0: Disable

0: Wait For Stop
1: Immediate (Auto mode only)
Sets the amount of time each motor will run
before the drive switches to the other motor.
Sets the amount of time that the drive will
delay starting if a Run command is present
at power-up.
When P1-01, Pump Mode, is set to 3
(MEMOBUS network), the drive is
unavailable to the network (Pump Off
Network) when the function is active.
Setting this parameter to 0.0 disables the
function.
0: Normally open (closed indicates the Low
City Pressure condition)
1: Normally closed (open indicates the
Low City Pressure condition)
Sets the amount of time a Low City Pressure
condition needs to be present before the
drive will stop.
Sets the amount of time a Low City Pressure
condition needs to be absent before the
drive will restart.

Description
Sets the amount of time to delay the drive
output and to energize the digital output
(H2-oo = 8B) before the drive is allowed
to run.
Setting this parameter to 0.0 disables the
function.
For normal PI operation during Pre-charge
2, if the PI Feedback signal rises above the
P4-32 level, Pre-charge 2 is cancelled and
the drive resumes normal operation.
For inverse PI operation and during Pre-
charge 2, if the PI Feedback signal goes
below the P4-32 level, Pre-charge 2 is
cancelled and the drive resumes normal
operation.
When set to zero, Pre-charge 2 still runs
when P4-07 is set, but uses P4-01 to
determine if normal operation should
resume.
0: Analog input
Note: Analog input is defaulted
to input A3 (0-10 V).
1: P5-02 (HAND reference)
Sets the frequency reference used when
HAND Mode is active and P5-01 is set to 1.
0: Disabled
1: Enabled
0: Disabled
1: Enabled
Sets the frequency reference used when

Detects loss of prime in the pump.
When the measured quantity determined by
P1-18 drops below this level for the time set
in P1-20 and the output frequency is at the
level set in P5-02, 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.
Detects loss of prime in the pump.
When the measured quantity determined by
P1-18 drops below this level for the time set
in P1-20 and the output frequency is at the
level set in P5-05, 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.
Enables and disables flow meter functions,
sets the scaling for the "Flow Rate" analog
input and output, and sets the display
scaling when "Flow Rate" is used as the PID
feedback.
Sets the scaling for the turbine in pulses per
gallon.
Pulses/Gallon = P6-02 + P6-03
This parameter is internally lower-limited
to 0.0001 ppG.
0: U.S. Gallons / min (GPM)
