Extended operating range of plug-and- play inverter

Published:  13 August, 2009

.Weg has extended the application range of its benchmark CFW-11 variable frequency inverter, with an IP54 variant of the highly successful plug-and-play drive. Integrating all of the features of the standard CFW-11, the IP54 version offers extended scope for operation in harsh environments such as food and beverage, providing high levels of protection against the ingress of dust and splashing water.

In addition to providing safeguards for inverter control operations in tough applications, the IP54- rated CFW-11 offers users the benefits of Weg's patented Optimal Flux technology. This minimises the losses of Totally Enclosed Fan-Cooled (TEFC) induction motors used with constant and variable torque loads, especially at low speeds where motor ventilation systems are inefficient. Optimal Flux overcomes the problem of reduced torque under these operating conditions, and the costs of traditional solutions such as motor oversizing and additional ventilation; providing instead an integrated, low cost solution for keeping motor temperature rise within the thermal limits of its insulation class.

As well as delivering optimised control of motors, even at low speeds, the CFW-11 IP54 provides users with an easy- to- use, universal drive platform; offering plug-and-play technology that is automatically configured, enabling the inverter to suit the widest range of drive applications: standalone, and centralised and decentralised with networks. This flexibility provides a wealth of integration possibilities; lowering total system costs whilst improving productivity In addition, it enables users to standardise on one product for all types of VFD control, with the commensurate benefits of savings on equipment costs, inventory, training and maintenance requirements.
