description
Motor rated voltage (as shown in the motor plate)
Average voltage drop due to the inverter is between 20
V and 30 Vrms based on load condition, so when the
input voltage is 230 V the average output voltage will
be between 200 V and 210 Vrms.
Refers to the voltage increase during the start up of the
motor.
Max current absorbed by the motor.
This parameters allows the possibility to limit the
current to the motor limiting as well the hydraulic
performances.
Maximum frequency of the motor. Note: by reducing
the maximum frequency of the motor, maximum
current will be reduced as well.
Minimum frequency of the motor. Note: for 4HS pump
is not advisable to set minimum frequency lower than
40 Hz in order to protect the integrity of the thrust
bearings.
Ramp-up time to reach the speed required to achieve
the set pressure (or frequency value). Longer times
delay the system reaching the pre set value but better
protect system components.
Excessively long ramp-up times can create difficulties in
CM setup, and can also cause false overload alarms.
Ramp-down time to reach zero speed. Longer times
keep the system pressurized, while protecting the
system components.
Excessively long ramp-down times can create
difficulties in CM setup. Excessively short ramp-down
times can cause false overload alarms.
