6.21 Sleep Wake Mode
Sleep function is mainly used in pump water supply, air supply control fields requiring
automatic sleep,this function can make inverter output 0 Hz when reaching user setting
preset sleep leve which realize energy saving. Sleep function needs to be combined with
PID function.See process diagram 6-9-6.
If the sleep function is switched on （F8.37 set to 1，F9.28（Close loop run mode）
set to 1（run when stop））， and the system is in running mode，When the output frequency
is detected less than or equal to the sleep frequency（F8.38） and the duration reaches the
sleep delay time（F8.39）, inverter enters the sleep mode automatically（Inverter run in0Hz）；
When PID feedback（Fd .29）is less than PID reference（Fd .28），and the deviation is more
than wake leve（F8.40）， and the duration reaches the wake delay time（F8.41），inverter
enters the wake mode automatically,and the system leave sleep mode automatically and
inverter run again.
