PID Regulator
Refer to detailed description of PID Regulator
parameters (P520 to P528).
When
P203
is changed to
1, P265
is changed
automaticallyto 15 (DI3 = manual/automatic).
Thevector control allows a better performance regarding
to torque and speed control. The CFW-08 vector control
operateswithout motorspeed sensor(sensorless).Itmust
be applied whenfollowing performances arerequired:
- Better dynamics (faster accelerations and stoppings).
-
When more accurate speed control is required.
- When hightorques at lowspeeds are required (

5 Hz).
Ex

mpl
e
s:
in positioning, such as load moving, packing
machines, dosing machines, etc.
The vector control can not be used in multimotor
applications.
The performance of the vector control with a switching
frequency of 10 kHz is not so good as when a switching
frequencyof 5 kHz or 2.5 kHz is used. It is not possible to
usea vector control witha switching frequencyof 15kHz.
For more details about the vector control, refer to item
6.2.3.
