[SVC V]
(UUC): Sensorless vector control with internal speed loop based on voltage feedback calculation. For applications
needing high performance during starting or operation.
[Standard]
(Std):
Standard motor law . For simple applications that do not require high performance. Simple motor control law
keeping a constant Voltage Frequency ratio, w ith a possible adjustment of the curve bottom This law is generally used for motors
connected in parallel. Some specific applications with motors in parallel and high performance levels may require

Note:
U0 is the result of an internal calculation based on motor parameters and multiplied by UFr (%). U0 can be adjusted by
modifying UFr value.
