description
Sets the difference between the
selected pressure (SETPOINT)
and the effective restart pressure
Sets the nominal frequency of the
motor
The set value MUST be the same
as the value indicated on the
motor plate
Sets the minimum operating
frequency
Sets the maximum operation
frequency.
CAUTION!! Increasing the
maximum frequency above the
nominal frequency may cause
significant motor overload.
Sets the pump stop delay under
dry running conditions
CAUTION: high values of the stop
delay may damage the pump
parameter not active
parameter not active
Sets the interval between two
successive automatic attempts to
restart following stops for "dry
running"
Setting the value to "0" excludes
attempts for automatic restarts
Sets the pump stop delay under
no flow conditions
Sets the inverter response speed
to pressure changes
The response value selected
depends on the characteristics of
the system
