No.
(Hex.)
Name Description
Default
(Range)
Ref.
Y2-03
(3C66)
RUN
Sleep Delay Time Sets the delay time before the drive enters Sleep Mode when the drive is at the sleep level
set in Y2-02 [Sleep Level].
5 s
(0 - 3600 s)
413
Y2-04
(3C67)
RUN
Sleep Activation Level Sets the level above which the output frequency must increase to activate the Sleep
Function when Y2-01 = 0, 3, or 5 [Sleep Level Type = Output Frequency, Output Speed
(RPM), or Output Frequency (non-PID)].
Note:
When you set this parameter to 0.0, this function will not be active, and the Sleep
Function will activate above the minimum speed (largest value from d2-02 [Frequency
Reference Lower Limit], Y1-06 [Minimum Speed], and Y4-12 [Thrust Frequency]).
0.0
(0.0 - 6000.0)
413
Y2-05
(3C68)
RUN
Sleep Boost Level Sets the quantity of boost that the drive applies to the setpoint before it goes to sleep.
Note:
Set this parameter to 0.00 to disable Sleep Boost Function.
0.00%
(0.00 - 600.00%)
413
Y2-06
(3C69)
RUN
Sleep Boost Hold Time Sets the length of time that the drive will keep the boosted pressure before it goes to sleep. 5.0 s
(0.5 - 160.0 s)
414
Y2-07
(3C6A)
RUN
Sleep Boost Max Time Sets the length of time that the system (feedback) has to reach the boosted setpoint. The
system must reach the boosted setpoint in the time set in this parameter, or it will go to
sleep.
20.0 s
(1.0 - 160.0 s)
414
Y2-08
(3C6B)
RUN
Delta Feedback Drop
Level
Sets the level of the PID Error (set-point minus feedback) to deactivate the Sleep Mode
operation.
Note:
Set this parameter to 0.00 to disable the function.
0.00%
(0.00 - 600.00%)
414
Y2-09
(3C6C)
RUN
Feedback Drop Detection
Time
Sets the time during which the software monitors the feedback to detect a flow/no-flow
condition. Refer to Y2-08 [Delta Feedback Drop Level] for more information.
10.0 s
(0.0 - 3600.0 s)
414
Y2-23
(3C7A)
RUN
Anti-No-Flow Bandwidth Sets the quantity of PI error bandwidth that the drive uses to detect an Anti- No-Flow
condition.
Note:
Do not set this parameter value too high, because operation can become unstable.
0.00%
(0.00 - 2.00%)
414
Y2-24
(3C7B)
RUN
Anti-No-Flow Detection
Time
Sets the time delay before the drive starts the increased deceleration rate after it detects
Anti-No-Flow.
10.0 s
(1.0 - 60.0 s)
414
Y2-25
(3C7C)
RUN
Anti-No-Flow Release
Level
Sets the amount below the setpoint which the feedback must decrease before the drive will
disengage Anti-No-Flow and return to normal PI operation.
Note:
The display unit and scaling change when the System Units change.
0.30%
(0.00 - 10.00%)

(3CFA)
RUN
Pre-Charge Level Sets the level at which the drive will activate the pre-charge function when the drive is
running at the frequency set in Y4-02 [Pre-Charge Frequency].
Note:
The drive will stop when one of these conditions is true:
• The feedback level increases to more than Y4-01
• The pre-charge time set in Y4-03 [Pre-Charge Time] expires
0.00%
