Intelligent Thermal Management

Due to the constant evolution of industrial processes and machines, efficient and effective solutions are increasingly required. The CFW900 has a unique thermal management function that allows its use in environments with different temperatures. From an integrated system, the VSD can measure the ambient temperature and configure itself by varying its switching frequency, thus becoming a versatile VSD and enabling its use in different industrial applications.

WEG High Performance Technology

Vectrue Technology®

Different Types of Controls for Your Application

Induction Motor

• Scalar: motor speed control with slip compensation.
• VVW (Voltage Vector WEG) – voltage vector control: motor speed control with automatic adjustment to load and power supply variations.
• Sensorless vector (without encoder) – induction motors: torque and speed vector control with excellent dynamic response, even at low speeds.
• Vector with encoder: the encoder module makes the interface between the CFW900 and the motor, providing a closed-loop speed and position control with excellent precision and dynamic response across the entire speed range (even with the motor stopped).

PM Motor

• VVW PM is a method to control permanent magnet motors. It is ideal for medium and high speed applications where the main requirement is energy efficiency, such as: fans, pumps and compressors.
