WEG expands CFW11 variable speed drive range

WEG has added a frame size H variable speed drive to its CFW11 series to help optimise processes and boost productivity in high power level applications. Available in two versions, covering the voltage range from 380 to 690V and the power range from 450 to 710kW in normal operation, the CFW11 can control both squirrel-cage and permanent-magnet motors and is designed for normal and heavy load operation in industrial and commercial applications.

Plug-in extension modules are available for adapting the variable speed drives to the engineer's needs and are automatically recognised by the device for plug-and-play operation. The standard model also features an integrated micro-PLC, enabling users to program their own applications using the included WLP software.

CFW11 variable speed drives support both voltage vector control and U/f control characteristics for use in safety-critical applications. WEG also integrates protection functions with fault and alarm indications, as well as EN ISO 13849-1 safe shutdown as an optional module.

The CFW11 enclosure is rated IP20 with an IP54 version optionally available with through-hole PCB assembly for the power stage. The CFW11 series supports the Modbus RTU, CANopen, DeviceNet, Pro?bus DP/DPV1, Pro?net, Modbus TCP, Ethernet/IP, Ethercat and BACnet communication protocols.
