414 YASKAWA SIEPYAIH6B01A HV600 AC Drive Bypass Technical Reference
Note:
Set this parameter to 0.00 to disable Sleep Boost Function.
■ Y2-06: Sleep Boost Hold Time
No.
(Hex.)
Name Description
Default
(Range)
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)
■ Y2-07: Sleep Boost Max Time
No.
(Hex.)
Name Description
Default
(Range)
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)
■ Y2-08: Delta Feedback Drop Level
No.
(Hex.)
Name Description
Default
(Range)
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. 0.00%
(0.00 - 600.00%)
When the drive enters Sleep Mode, the software monitors the feedback to detect a flow-no flow condition. The drive
will deactivate the Sleep Mode operation and will go back to its normal operation when:
• The PID Error is more than this level in the time set in Y2-09 [Feedback Drop Detection Time]
• The output frequency is more than the level set in Y1-06 [Minimum Speed]
Note:
Set this parameter to 0.00 to disable the function.
■ Y2-09: Feedback Drop Detection Time
No.
(Hex.)
Name Description
Default
(Range)
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)
■ Y2-23: Anti-No-Flow Bandwidth
No.
(Hex.)
Name Description
Default
(Range)
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. 0.00%
(0.00 - 2.00%)
Note:
Do not set this parameter value too high, because operation can become unstable.
■ Y2-24: Anti-No-Flow Detection Time
No.
(Hex.)
Name Description
Default
(Range)
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)
