Note:
Sleep activates when the selected level type (P2-01 setting)
reaches the programmed sleep level for the time set in P2-03.
This function is active when the drive is running during AUTO
Mode. When P1-01 is set to 3 (MEMOBUS network), the
Sleep Level function is active when there is only one drive running on the
network.
Setting this parameter below minimum pump speed (P1-06)
disables Sleep Level (P2-02) and sleep activates at minimum
pump speed.
Sets the delay time before the drive enters Sleep Mode when the
sleep level set in P2-02 is reached.
Sleep Delay Time
Sets the level above which the output frequency must rise to
activate the sleep function when P2-01, Sleep Level Type, is set
Sleep Act. Level to 0 (Output Frequency / Speed).
Setting this parameter to 0.0 disables the function and the sleep
function will activate when P2-02, Sleep Level, is reached.
Sets the amount of boost applied to the setpoint before going to
sleep.
Sleep Boost Lvl
Setting this parameter to 0.0 disables the function.
Sets the amount of time that the boosted pressure will be
maintained before the drive goes to sleep.
Sets the amount of time that the system (feedback) has to reach
SleepBoost MaxTm the boosted setpoint. The drive will go to sleep when the amount
of time set in this parameter has been exceeded.
If the PID Error (setpoint minus feedback) exceeds the level
programmed in this parameter within the time window set in
P2-09 and the output frequency is greater than the level set in
D Fb Drop Level
P1-06, the sleep operation deactivates and the drive returns to
normal operation.
Setting this parameter to 0.0 disables the function.
Defines the time window in which the software monitors the
feedback to detect a flow/no-flow condition.
FB Drop Det. Time
Sets the maximum number of cycles that are allowed within the
time specified in P2-11 before tripping the PoC "Pump Over
Cycle" fault.
One cycle is defined when the drive transfers from normal
operation in AUTO Mode to Sleep Mode.
Cycle Protection
This function is active when the drive is running during AUTO
Mode. When P1-01 is set to 3 (MEMOBUS network), the
function is active when there is only one drive running on the
network.
Setting this parameter to 0 disables the function.
Sets the maximum time allowed between cycles. When no
cycling occurs within the programmed time, the drive will

decrease the internal cycle register.

Description
Feedback depends on PID direction operation.
