PUMP
Allows selection of the motor control type suitable for the application and the required performances.
v
Performance: SVCU; Sensorless vector control with internal speed loop based on voltage feedback 
calculation. For applications needing high performance during starting or operation. 
v
Standard: U/F 2 points (Volts/Hz) without internal speed loop
For simple applications that do not require high performance. Simple motor control law keeping a constant 
Voltage Frequency ratio, with a possible adjustment of the curve bottom.
This law is generally used for motors connected in paralell. Some specific applications with motors in 
paralell and high performance levels may require 
PErF
.
v
Pump: U²/F; dedicated to variable torque pump and fan applications that do not require high starting torque.
