P4-03
(0CFC) Pre-Charge Time
Pre-Charge Time
Sets the maximum allowed Pre-Charge time.
When P1-01 is set to 3 (MEMOBUS network), the function is
active only on the first drive to run in the network.
Setting this parameter to 0.0 disables the function.
Default: 0.0 min
Min.: 0.0
Max.: 3600.0
P4-05
(0CFE) Pre-Charge Loss of
Prime Level
Pre-Charge LOP
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 P4-02, 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.
Default: 0.0 A
<2>
Min.: 0.0
Max.: 1000.0

P4-06
(0CFF) Pre-Charge Frequency 2 Pre-Charge Freq2
Sets the frequency reference used when the Pre-Charge function
2 is active.
Setting this parameter to 0.0 disables the function.
Default: 0.0 Hz
Min.: 0.0
Max.: [E1-04]
–
P4-07
(0D00) Pre-Charge Time 2
Pre-Charge Time2
Sets the time at which the drive will spend at the Pre-Charge
frequency 2 speed during pre-charge.
Setting this parameter to 0.0 disables the function.
Default: 0.0 min
Min.: 0.0
Max.: 3600.0

P4-08
(0D01) Pre-Charge Loss of
Prime Level 2
Pre-Charge LOP 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.
Default: 0.0 A

P4-11
(0D04) Thrust Bearing
Acceleration Time
Thrust Acc. Time
Sets the time at which the drive output frequency will ramp up
to the reference frequency set in P4-12.
Default: 1.0 s
Min.: 0.0
Max.: 600.0
–
P4-12
(0D05) Thrust Bearing
Frequency
Thrust Freq.
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.
Default: 30.0 Hz
Min.: 0.0
Max.: [E1-04]
P4-13
(0D06) Thrust Bearing
Deceleration Time
Thrust Dec Time
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.
Default: 5.0 s
Min.: 0.0
Max.: 600.0
–
P4-17
(0D0A) Utility Start Delay
Utility Delay
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.
Default: 0.2 min
Min.: 0.0
Max.: 1000.0

1: Normally Closed
Selects the type of pressure switch connected to the “Low City
Press” digital input (H1-0o = 73).
0: Normally open (closed indicates the Low City Pressure
condition)
1: Normally closed (open indicates the Low City Pressure
condition)
Default: 1
Range: 0, 1

Sets the amount of time a Low City Pressure condition needs to
be present before the drive will stop.
Default: 10 s
Min.: 1
Max.: 1000
–
P4-23
(0D10) Low City Off-Delay
Time
