3 ABOUT THE CFW700
The CFW700 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.
