The following options are available:
VLT® Motion Control Tool MCT 10 offers advanced programming functionality for all Danfoss drive products, greatly reducing programming and set-up time. MCT 10 Basic allows access to a finite number of drives with limited functionality.
With VLT® Motion Control Tool MCT 31 you can determine whether harmonics will be an issue in your installation when drives are added. MCT 31 estimates the benefits of adding various harmonic mitigation solutions from the Danfoss product portfolio and calculates system harmonic distortion.
The Danfoss VLT 12-Pulse Drive offers reduced harmonics for demanding industry applications above 250 kW.
The VLT 12-Pulse Drive is a high efficiency variable frequency converter which is built with the same modular design as the popular 6-pulse VLT drives. It is offered with similar drive options and accessories and can be configured according to customer need. Together with the needed 30°-phase shifting transformer the solution provides durability and reliability at a low cost. Under ideal grid conditions the solution eliminates the 5th, 7th, 17th and 19th harmonics and results in a THiD of around 12% at full load. The needed transformer makes this solution ideal for applications where stepping down from medium voltage is required or where isolation from the grid is needed. The Danfoss VLT 12-Pulse Drive provides harmonic reduction without adding capacitive or inductive components which often require network analysis to avoid potential system resonance problems.
