YASKAWA TOEP YAIP1W 02E YASKAWA AC Drive - iQpump1000 Installation & Start-up Guide
Description
0: Output frequency
1: Output current
2: Feedback
3: Output speed (RPM)
4: Flow meter (requires flow meter)
Note: Feedback depends on PID
direction operation.
Sleep activates when the selected level type
(P2-01 setting) reaches the programmed
sleep level for the time set in P2-03.
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 when there is only one
drive running on the network.
Setting this parameter below minimum
pump speed (P1-06) disables Sleep Level
(P2-02) and sleep activates at minimum
pump speed.
Sets the delay time before the drive enters
Sleep Mode when the sleep level set in
P2-02 is reached.
Sets the level above which the output
frequency must rise to activate the sleep
function when P2-01, Sleep Level Type, is
set to 0 (Output Frequency / Speed).
Setting this parameter to 0.0 disables the
function and the sleep function will activate
when P2-02, Sleep Level, is reached.
Sets the amount of boost applied to the
setpoint before going to sleep.
Setting this parameter to 0.0 disables the
function.
Sets the amount of time that the boosted
pressure will be maintained before the drive
goes to sleep.
Sets the maximum number of cycles that are
allowed within the time specified in P2-11
before tripping the PoC "Pump Over Cycle"
fault.
One cycle is defined when the drive
transfers from normal operation in AUTO
Mode to Sleep Mode.
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 when there is only one
drive running on the network.
Setting this parameter to 0 disables the
function.
Sets the maximum time allowed between
cycles. When no cycling occurs within the
programmed time, the drive will decrease
the internal cycle register.
0: Disabled
1: Alarm
2: Fault
3: Auto SP Compensation
Allows for the software to automatically
compensate the setpoint in the event of
excessive cycling.
Sets the maximum allowed setpoint
compensation for over-cycling function.
Sets the amount of PI error bandwidth used
to detect the Anti-No-Flow condition.
Avoid setting this parameter value too high,
as operation may become unstable.
Setting this parameter to 0.00 will disable
the function.
Sets the time delay before the drive starts
the increased deceleration rate after Anti-
No-Flow is detected.

Description
Sets the amount below the setpoint which
the feedback must drop to disengage the
Anti-No-Flow and return to normal PI
operation.
Selects the method for adding contactor
pumps to the system.
0: Output frequency (Uses P3-03 and
P3-05)
1: Feedback (Uses P3-04 and P3-05)
2: Feedback + Fout (Uses P3-03, P3-04, and
P3-05)
Selects the method for removing contactor
pumps from the system.
0: Output frequency (Uses P3-09, P3-50
P3-60, P3-70, P3-80, and P3-90)
1: Feedback (Uses P3-08 and P3-09)
2: Feedback + Fout (Uses P3-08, P3-09,
P3-50, P3-60, P3-70, P3-80, and P3-90)
Sets the maximum level used for the
multiplex pumping operation.
Parameter is active only when P3-01 is set
to 0 or 2.
When P3-01 is set to 0, the next available
pump will be added to the system by a
multi-function Discrete Output closure
(H2-0o = 80 to 84) when the output
frequency rises above the level set in this
parameter for the time set in P3-05.
When P3-01 is set to 2, the next available
pump will be added to the system by a
multi-function Discrete Output closure
(H2-0o = 80 to 84) when the output
frequency rises above the level set in this
parameter and the delta feedback (setpoint
minus feedback) has exceeded the level
programmed in P3-04 for the time set in
P3-05.
Sets the level used for the multiplex
pumping operation.
Parameter is active only when P3-01 is set
to 1 or 2.
When P3-01 is set to 1, the next available
pump will be added to the system by a
multi-function Discrete Output closure
(H2-0o = 80 to 84) when the delta feedback
(setpoint minus feedback) has exceeded the
level set in this parameter for the time set in
P3-05.
When P3-01 is set to 2, the next available
pump will be added to the system by a
multi-function Discrete Output closure
(H2-0o = 80 to 84) when the output
frequency rises above the level set in P3-03
and the delta feedback (setpoint minus
feedback) has exceeded the level set in this
parameter for the time set in P3-05.
Note: Programming this
parameter too close to the
system setpoint may cause
the pump system to cycle
excessively.
to the system.
Sets the upper limit of the output frequency
after a lag pump is staged.
The upper limit of the output frequency is
calculated by subtracting the value of this
parameter from parameter P3-03.
Output limit = P3-03 - P3-06
Sets the amount of time that the output
frequency will be limited after lag pump is
staged.
