P2-07
(0C6A) Sleep Boost Maximum
Time
SleepBoost MaxTm
Sets the amount of time that the system (feedback) has to reach
the boosted setpoint. The drive will go to sleep when the amount
of time set in this parameter has been exceeded.
Default: 20.0 s
Min.: 1.0
Max.: 160.0
–
P2-08
(0C6B) Delta Sleep Feedback
Drop Level
D Fb Drop Level
If the PID Error (setpoint minus feedback) exceeds the level
programmed in this parameter within the time window set in
P2-09 and the output frequency is greater than the level set in
P1-06, the sleep operation deactivates and the drive returns to
normal operation.
Setting this parameter to 0.0 disables the function.
Default: 0.0 PSI
<3>
Min.: 0.0
Max.: 6000.0
–
P2-09
(0C6C) Feedback Detection
Drop Time
FB Drop Det. Time
Defines the time window in which the software monitors the
feedback to detect a flow/no-flow condition.
Default: 10.0 s
Min.: 0.0
Max.: 3600.0
–
P2-10
(0C6D) Sleep Mode: Cycling
Protection
Cycle Protection
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.
Default: 0
Min.: 0
Max.: 10
–
P2-11
(0C6E)
Sleep Mode: Maximum
Cycling Protection
Time
Max. Cycle Time
Sets the maximum time allowed between cycles. When no
cycling occurs within the programmed time, the drive will
decrease the internal cycle register.
Default: 300 s
Min.: 0
Max.: 3600

P2-12
(0C6F) Over Cycling Mode
Over Cycle Mode
0: Disabled
1: Alarm Only
2: Fault
3: Auto SP Comp.
0: Disabled
1: Alarm
2: Fault
3: Auto SP Compensation
Default: 0
Range: 0 to 3
–
P2-13
(0C70) Setpoint Compensation Setpoint Comp.
Allows for the software to automatically compensate the
setpoint in the event of excessive cycling.
Default: 0.0 PSI
<3>
Min.: 0.0
Max.: 6000.0
–
P2-14
(0C71)
Maximum Setpoint
Compensation
Max. SP Comp.
Sets the maximum allowed setpoint compensation for over-
cycling function.
Default: 0.0 PSI
<3>
Min.: 0.0
Max.: 6000.0
–
P2-23
(0C7A) Anti-No-Flow
Bandwidth
ANF Bandwidth
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.
Default: 0.40%
Min.: 0.00
Max.: 2.00
–
P2-24
(0C7B) Anti-No-Flow
Detection Time
ANF Det. Time
Sets the time delay before the drive starts the increased
deceleration rate after Anti-No-Flow is detected.
Default: 10.0 s
Min.: 1.0
Max.: 60.0
–
P2-25
(0C7C) Anti-No-Flow Release
Level
ANF Release Lvl
Sets the amount below the setpoint which the feedback must
drop to disengage the Anti-No-Flow and return to normal PI
operation.
Default: 3.0 PSI
<3>
Min.: 0.0
Max.: 100.0

<1> Display units vary depending on the setting for P2-01, Sleep Level Type. When P2-01 is set to 0, the display units are “Hz”; setting 1 is “A”; setting
2 is P1-02 Selection; setting 3 is “RPM”; setting 4 is P6-04 selection.
<2> Display units vary depending on the setting for P2-01, Sleep Level Type. When P2-01 is set to 0, 1, 2, or 4, the display units are “Hz”; setting 3 is
“RPM”.
<3> Unit is determined by P1-02, System Units, setting.
