Description
Defines the minimum motor speed. At any value
below this speed, the MPPT function is not active
and drive stops functioning. The drive auto
restarts after the time defined in
time. This setting avoids unnecessary operation
of pump at low speed.
Note: Setting the value at 500 can helps to create
suction in the pump.
Speed.
Defines the maximum motor speed.
Speed.
Defines the DC voltage above which
is effective. Below this value, motor speed
factor
follows the V/F factor.
DC voltage.
Defines the factor at which the drive functions
the best. This parameter is effective when DC
voltage is above the value in the parameter
Boost factor.
Boost factor.
Allows drive to wait for this time to restart
automatically when drive trips due to
undervoltage fault, PV cell maximum voltage
fault or when actual speed decreases below the
minimum motor speed defined in the parameter
