Y2-08 Delta Feedback Drop Level
(3C6B)
RUN
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.

RUN
Note:
Do not set this parameter value too high, because operation can become unstable.

Sets the length of time that the drive will keep the boosted pressure before it goes to sleep.
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.
Sets the level of the PID Error (set-point minus feedback) to deactivate the Sleep Mode operation.
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.
Sets the quantity of PI error bandwidth that the drive uses to detect an Anti- No-Flow condition.
Sets the time delay before the drive starts the increased deceleration rate after it detects Anti-No-
Flow.
