The CFW900 is a high-tech VSD for driving and controlling three-phase induction and permanente magnet motors. It offers excellent static and dynamic performance and highly precise torque, speed and position control. It can be used in a wide range of applications due to its high overload capacity. Thanks to its technology, the CFW900 variable speed drive provides energy savings, safety, increased productivity and quality in the process network in which it is implemented.
Human-Machine Interface
The CFW900 HMI offers a smart, modern and easy-to-use interface with simple and fast interaction.
- Graphic HMI;
- Detachable Keypad;
- Selection of the Direction of Rotation;
- Local/Remote Selection;
- Bluetooth Connectivity® ( Check the availability of local certification);
- RTC – Real-time clock;
- Start Key;
- Stop Key;
- JOG Key.
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.
Connectivity
The CFW900 can be connected to the main industrial communication networks without additional modules, as it has two switch Ethernet ports for EtherNet/IP, Modbus-TCP and MQTT communication, and a serial port (RS485) for Modbus-RTU communication.
The new CFW900 HMI with Bluetooth® connectivity is ideal for panel builders and technical assistants, as, in conjunction with the new WPS Mobile app, it allows parameter monitoring with customized layout and components as well as parameterization, backup, restoration of parameters, and more.
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.
