Sleep & Wake-Up
18.1
Sleep Mode
When the system pressure is high enough (feedback is above setpoint) and the Main drive output frequency is
decreasing, the Lag drives will stop based on the alternating sequence AP1-49 (ALT Sequence). With only the Main
drive running, it will eventually go into Sleep mode.

Main drive Sleep Frequency. Note: If minimum speed (freq) is
set at MC2-46 (PID-31), Sleep Freq must be above minimum.
Low Freq~ High
Freq
When the Main drive output frequency goes below the sleep frequency MC2-41 (PID Sleep0Freq) and the delay
time MC2-40 (PID Sleep 0 DT) has expired, the Main drive will go into Sleep mode.
18.2
Sleep Boost
Sleep Boost can be used to increase the pressure before going into Sleep mode which will extend Sleep mode time.

Sleep Boost.
Low Freq~ High
Freq
When Sleep mode conditions of Sleep Freq (PID-62) and Delay Time (PID-63) are met, before entering Sleep mode,
the output frequency is accelerated to the Sleep Boost Freq PID-61 (Sleep Bst Freq). When the pressure (feedback)
exceeds the sleep boost amount PID-60 (Sleep Bst Set) above the setpoint, the Sleep Boost operation is stopped,
and the drive enters Sleep mode.
18.3
Wake Up
During Sleep mode, when the system pressure (feedback) decreases, the Main drive will resume operation.

When the pressure (feedback) falls below the setpoint by the amount set in the wake up level PID-65 (PID
WakeUp0Dev) and for the delay time set in PID-64 (PID WakeUp0 DT), the Main drive will Wake Up and resume
operation.
