www.weg.net CFW11 - System Drive The CFW11 is a system drive designed for the control of squirrel cage induction motor as well as permanent magnet type ones. Since it was developed for running on Normal and Heavy Duty mode, a big variety of applications can be achieved. Designed for exclusively industrial or professional use, provides increased productivity with excellent performance and an improvement in the quality of the process in which it is used.

www.weg.net Technical Features Built-In DC Link Reactor JJ Allows the VSD to be installed in any network (there is no minimum impedance restriction) JJ Typical power factor (PF) for rated condition: JJ 0.94 for models with three-phase supply JJ 0.70 for models with single-phase 0.70 for models with single-phase supply/three-phase supply = 0.94 JJ Displacement power factor > 0.
www.weg.net Flexibility is Our Philosophy The CFW11 was developed based on Plug & Play philosophy, identifying automatically the accessories plugged in, as well as easy installation and safe operation with no need for extra configuration.
www.weg.net Applications The CFW11 can be used in both simple and sophisticated applications, due to its broad range of functions and easy configuration, installation and operation. The CFW11, through its vectrue inverter technology, presents excellent static and dynamic performance, precise torque and speed control, dynamic response, positioning precision, and high overload capacity.

www.weg.net Accessories Kit for Power Cable Shielding CFW11 has a kit to simplify the connection of the motor cable shield to ground, providing a low-impedance connection for high frequencies.
www.weg.net Optionals Safety Stop in Accordance with EN 61800-5-2, EN ISO 13849-1, IEC 62061, IEC 61508 Parts 1-7, EN 50178, IEC 60204-1, Cat. 3/PL d acc. and SIL CL2 acc. With the activation of the safety stop function, the PWM pulses of the IGBTs are disabled. Since no torque is applied to the motor thus, it is ensured that the motor remains stopped providing system safety. Note: this optional must be factory fitted (see product coding on page 17).
www.weg.net PLC11 PLC Accessories PLC11 accessory provides the CFW11 with PLC functionality, speed reference generator and motion control functions. It comes in two options: PLC11-01 and PLC11-02 (see differences in the table below). In many applications, these accessories allows the CFW11 to replace an external PLC, reducing application costs.

It ensures that the programming will not be lost as there is a backup of the parameters It permits the transfer of parameters stored in the flash memory module to the CFW11 and vice versa.
www.weg.net USB Connection Trace Function Trace function is used to register CFW11 variables (like current, voltage, speed, etc.) when a given event occurs in the system (eg.: alarm / fault, overload, overvoltage, etc.). When a given event takes place, the trigger function activates data storage process. The stored variables can be visualized in the form of graphs by using the SuperDrive G2 software. Trace function simulates a 4-channel oscilloscope.
