Function
This is the minimum speed for the speed operation in DC current when the MPPT function is enabled.
If speed drops below this threshold for a time 6 *
P812
(6-fold the MPPT Activation Period), the pump
is stopped during the ramp according to the preset ramps (see section 2.6.1) and is restarted when
the time set in parameter
P802
has elapsed.
