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.
