Sleep Activate Level
SLP Act. Level
When P2-01 Sleep Level Type is set for 0 (Output Frequency) or 3
(Output Speed). The sleep function becomes active when output
frequency is greater or equal to the level P2-20. When programmed
to 0, sleep function will become active in above P2-02 Sleep Level.
Display Units for Sleep Level P2-20:
P2-01 = 0, => “Hz”
P2-01 = 1, => “Hz”
P2-01 = 2, => “Hz”
P2-01 = 3, => “rpm”
P2-01 = 4, => “Hz”
A value of 0 disables this function.

Thrust Bearing Acceleration
Time
Thrust Acc Time When enabled (P4-05>0) the drive output frequency will ramp up to
the specified reference frequency in P4-05 in the time specified in
P4-04. <1> PI mode is automatically disabled.

P4-06
Thrust Bearing Deceleration
Time
Thrust Dec Time
This is the amount of time that it will take to bring the drive from
Thrust Frequency (P4-05) to stop when Thrust Mode is active. Any
time the Run Command is removed while the drive is operating in
Thrust Mode above the Thrust Frequency, this deceleration time will
be used once the frequency reference is at or below the Thrust
Frequency.

Loss of Prime Time
Prime Loss Time
Delay time before a Loss of Prime fault occurs. Pump protection
criteria specified P1-14 must be met for the drive to fault. On fault the
drive will coast to a stop.

Sleep Boost Level
Sleep Boost Lvl
Sets the amount of boost applied to the setpoint just before going to
sleep. A setting of 0.0 disables the sleep boost function. (Internally
limited to 25% of P1-03).

Sleep Boost Maximum Time
Sleep Boost Time
Sets the amount of time the system (feedback) has to reach the
“boosted” setpoint. If more than this time elapses, the drive will go to
sleep.

Message Display Description
Sleep Boost Active
The drive is entering the sleep mode and the pressure setpoint is being boosted.
During this time, the U1-01 monitor will be updated with the boosted setpoint.
Alarm Display Description Countermeasures
Freq. Ref <
Pump Min P1-06
The drive's frequency reference is set less than the Minimum Pump Frequency P1-06.
The frequency reference will be lower-limited to P1-06 during this time.
This will only be active when:
-Drive is NOT in PI mode
-Drive is running
-Minimum Pump Frequency is enabled (P1-06 > 0.00)
Increase the frequency reference to a value greater
than P1-06.
Freq. Ref <
Thrust P4-05
The drive's frequency reference is set less than the Thrust Bearing Frequency P4-05. The
frequency reference will be lower-limited to P4-05 during this time.
This will only be active when:
-Drive is NOT in PI mode
-Drive is running
-Thrust Bearing is enabled (P4-05 > 0.00)
Increase the frequency reference to a value greater
than P4-05.
