The Sensorless Vector Control permits high torques and quick response,
even at very low speeds and during the starting of the motor;
The “Optimal Braking” function allows controlledmotor brakingwithout using
a Dynamic Braking (DB) resistor;
“Self-tuning”auto-tunefunctionwithVectorControl,permittingautomaticsetting
of the control regulators and control parameters by means of the automatic
identification of the motor and the load parameters.
Technical specifications for each model of CFW-09 are described in chapter 9.
