0 = Sleep disabled
1 = Sleep according to P3.13.5.1 and
P3.13.5.2
NOTE!
Sleep in solar mode can be managed according to P3.13.5.1 and P3.13.5.2
When P3.22.1.5 = 1, the drive will stop if the output frequency is below the value in P3.13.5.1, for
the time in P3.13.5.2. It will restart as after a stop due to low power.
Sleep function allows to program a minimum frequency P3.3.1.1 that is below the efficient range
of the pump. MPPT can reach this low value, leading to a minimum output power and avoiding to
stop the drive in case of temporary reduced irradiation. If the condition persists, sleep logic will
then stop the drive.
