P1-19 Prime Loss Level
Detects loss of prime in the pump when in
Auto or Sleep Boost Mode.
P1-20 Loss of Prime Time

condition occurs. The pump protection
criteria set in P1-18 and P1-19 must be met
before the timer will start.

Sets the frequency level above which the
“Loss of Prime” detection is enabled when
set to a value other than 0.
P1-22
Loss of Prime

0: Fault
1: Alarm
2: Digital out only
P1-23

Maximum Restart
Time after Fault
Sets the time in minutes that the drive will
wait before attempting another restart when
the restart fails or is not attempted due to a
continuing fault condition.

P2-01 Sleep Level Type
0: Output frequency
1: Output current
2: Feedback
3: Output speed (RPM)
Note: Feedback depends on PID
direction operation.
P2-02 Sleep Level
Sleep activates when the selected level type
(P2-01 setting) reaches the programmed
sleep level for the time set in P2-03.
P2-03 Sleep Delay Time
Sets the delay time before the drive enters
Sleep Mode when the sleep level set in
P2-02 is reached.
P2-04 Sleep Activate Level
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).
P2-05 Sleep Boost Level
Sets the amount of boost applied to the
setpoint before going to sleep.
Setting this parameter to 0.0 disables the
function.
P2-06 Sleep Boost Hold Time
Sets the amount of time that the boosted
pressure will be maintained before the drive
goes to sleep.
P2-07
Sleep Boost Maximum
Time
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.
P2-08
Delta Sleep Feedback
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.
P2-09
Feedback Detection
Drop Time
Defines the time window in which the
software monitors the feedback to detect a
flow/no-flow condition.
P2-10
Sleep Mode: Cycling
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.
P2-11
Sleep Mode:
Maximum Cycling
Protection Time
Sets the maximum time allowed between
cycles. When no cycling occurs within the
programmed time, the drive will decrease
the internal cycle register.
No. Name Description
P2-12 Over Cycling Mode
0: Disabled
1: Alarm
2: Fault
3: Auto SP Compensation
P2-13
Setpoint
Compensation
Allows for the software to automatically
compensate the setpoint in the event of
excessive cycling.
P2-14
Maximum Setpoint
Compensation
Sets the maximum allowed setpoint
compensation for over-cycling function.
P2-23
Anti-No-Flow
Bandwidth
Sets the amount of PI error bandwidth used
to detect the Anti-No-Flow condition.
P2-24
Anti-No-Flow
Detection Time
Sets the time delay before the drive starts
the increased deceleration rate after Anti-
No-Flow is detected.
P2-25
Anti-No-Flow Release
Level
Sets the amount below the setpoint which
the feedback must drop to disengage the
Anti-No-Flow and return to normal PI
operation.
P4-01 Pre-Charge Level Runs the drive at the frequency set in P4-02.
P4-02 Pre-Charge Frequency Sets the frequency reference used when the
Pre-Charge function is active.
P4-03 Pre-Charge Time
Sets the time at which the drive will spend
at the Pre-Charge Frequency 1 during pre-
charge. Maximum pre-charge time is P4-03
+ P4-07.
P4-05
Pre-Charge Loss of
Prime Level
Detects loss of prime in the pump during
Pre-charge 1.
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 P4-02, 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.
P4-06
Pre-Charge Frequency
2
Sets the frequency reference used when the
Pre-Charge function 2 is active.
Setting this parameter to 0.0 disables the
function.
P4-07 Pre-Charge Time 2
Sets the time at which the drive will spend
at the Pre-Charge frequency 2 during pre-
charge. Maximum pre-charge time is P4-03
+ P4-07.
P4-08
Pre-Charge Loss of
Prime Level 2
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.
P4-10
AUTO Mode Operator
Run Power Down
Storage
0: Disabled
1: Enabled
WARNING!Sudden Movement Hazard. If
the drive is powered down while running, it
will automatically initiate an internal Run
command upon power-up.
P4-11
Thrust Bearing
Acceleration Time
Sets the time at which the drive output
frequency will ramp up to the reference
frequency set in P4-12.
P4-12
Thrust Bearing
Frequency
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.
