VFD's Motor Control

New CFW900 Variable Speed Drive

The CFW900 VSD is the most innovative product for driving and controlling motors in industrial machines and processes.

The CFW900 is a high-tech VSD for driving and controlling three-phase induction and permanent 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®
• 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

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.

Main Features

• Supply voltage:
  • 200 to 240 V single- or three-phase: output current 4.6 to 10.0 A (1.1 to 2.2 kW - 1.5 to 3.0 hp);
  • 200 to 240 V three-phase: output current 4.6 to 250 A (1.1 to 75 kW - 1.5 to 100 hp);
  • 380 to 480 V three-phase: output current 2.8 to 242 A (1.1 to 132 kW - 1.5 to 200 hp).

• Small size for better use of panel space;
• USB port incorporated into the HMI;
• Increased processing capacity;
• Possibility of memory expansion with 8GB MicroSD Card with industrial temperature;
• IoT Product - Ready with MQTT protocol in standard product;
• IE2 efficiency rating (IE C 61800-9-2 / EN 50598-2);
• Integrated STO (Safe Torque Off) and SS1-t (Safe Stop 1 time controlled) functions.

Frequency Inverter - CFW11 Series

High Productivity & Savings for Your Business

Offers high technology for control of three-phase induction motors and permanent magnets synchronous motors - Magnet.  The CFW11 series achieves the performance increase for most complex drive systems. Design exclusive for industrial or professional use, the CFW11 presents many innovations adding significant benefits to customers, a lot for its simplicity of installation and operation, based in the Plug-and-Play philosophy also allowing simple and quick installation of its accessories in cluing a Remote Keypad which can be installed on panel doors or machine consoles with IP56 protection degree.

Vectrue Technology®

• Linear and adjustable V/F, VVW (Voltage Vector WEG) and vector control are available on CFW11
• Two types of vector control: sensor less and closed loop vector control (encoder Interface required)
• Sensor less vector control permits high torque and quick response in open loop, even at low speeds
• The self-tuning function sets the vector control or VVW with the motor and to application load used
• By the adjustable V/F control, it is possible, for example, to adjust a quadratic V/F curve, providing energy savings for quadratic torque loads (e.g.: centrifugal pumps and fans)

Optimal Braking®

Applications involving high inertia loads, when applied short time deceleration, a large amount of energy returns from the motor to the VSD. To handle this energy, regular VSDs have to dissipate it as heat in power resistors. Such resistors are usually large, and some installation criteria must be considered due to their heat dissipation. As an alternative to the use of braking resistors, CFW11 features a special braking method in vector control mode known as Optimal Braking®. This innovation delivers a high-performance braking torque without requiring a braking resistor. 

SoftPLC Function

It is a resource that provides PLC features to the CFW11 without the addition of any accessories. It provides flexibility to the product, allowing the user to create his/her own applicative software (user’s program).

The SoftPLC main features are:

• Ladder language programming using WLP software
• Access to all VSD parameters and I/Os
• Configurable PLC, mathematical and control blocks
• Applicative software download, upload and online monitoring via USB connection
• Storage of user application in the CFW11 flash memory module (see below)
• Memory capacity of 15 kB for user application storage

Main Characteristics

• Power supply:
  • 200 to 240 V single-phase: output current from 6 to 10 A (2.0 to 3 cv)
  • 200 to 230/240 V three-phase: rated output current from 7.0 to 211 A (2.0 to 150 cv)
