WEG CFW-11 IP54 Variable Frequency DriveTuesday, 2 March 2010
Easy to Use Options
Easy to use configurations and operations are among the important benefits of the CFW-11 line. The Human/ Machine Interface (HMI) control panel, with its cell phone inspired function and jog-selection keyboard, is one way the operator can communicate with the drive, and covers 100% of the drive functionality. Uniquely among V/F drives, the CFW-11 IP54 also offers a USB port allowing functionality and updating of firmware through connection with a lap top. Alternatively, the CFW-11 IP54 is compatible with Profibus, DeviceNet, CANopen, Modbus and Ethernet communication protocols, for factory-wide DCS operation.
Self-configuration with Plug-and-Play accessories Easy and rapid upgrading and customizing of the CFW- 11 IP54 are facilitated by the plug-and-play modular click-in design of the accessory units which are inserted inside the control casing. The CFW-11 IP54 automatically recognizes and configures the accessory and option units for accurate and safe installation while eliminating the time and possible errors of manual configuration. Options available include I/O expansions, encoder interfaces, memory card and communication protocols.
In-built value and cost savings
Further customer value offered by the CFW-11 IP54 includes the internal PLC function that eliminates most requirements for an additional external PLC device. The SOFT-PLC function enables the creation of many possible applications like winding, multipump, cascaded control, crane or elevator.
