3.1 ABOUT THE CFW-11
The CFW-11 is a high performance Frequency Inverter that makes it possible the control of speed and torque
of three-phase AC induction motors. The principal characteristic of this product is the "Vectrue" technology,
which presents the following advantages:
Scalar Control (V/f), VVW or vector control programmable in the same product.
The Vector control can be programmed as "sensorless" (which means that standard motors, without the need
of encoder) or vector control with motor encoder.
The "sensorless" vector control allows high torque and fast response, even at very slow speeds or during starting.
The "Optimal Braking" function for the vector control allows a controlled motor braking, eliminating in some
applications the braking resistor.
The vector control "Self-Tuning" function allows the automatic setting of the regulators and control parameters,
from the identification (also automatic) of the motor and load parameters.
