Control Two Motors from a Single Drive

Control Two Motors from a Single Drive with Danfoss Drives’ new Dual Motor Selection Feature

16 June 2009
Danfoss Drives’ VLT® HVAC Drives are now available with a dual motor selection feature.  Available as a factory-installed option on new VLT HVAC drives, these individual motor overloads and fuses allow users to run two motors simultaneously from either the drive or the bypass.  With this new feature, users no longer need to purchase two drives to control two motors, resulting in reduced up-front costs, a smaller solution footprint and the elimination of start-up and commissioning costs associated with a second drive.
"Danfoss Drives offers a dual motor option on its standard HVAC drive panels. This feature is significant for users in that it enables them to single-source all of their panels, including the dual motor panels, as factory-warranted units. Choosing to purchase this option from Danfoss eliminates the costs and complexities of seeking a 3rd party solution," says Don Cameron, Product Manager.

The dual motor selection option is rated for use in temperatures up to 40°C, and is available with BACnet, Siemens APOGEE™ FLN, Johnson Controls Metasys® N2 and LonWoks serial communications capabilities.   This option is currently available on VLT HVAC Drives through 350 HP (460V or 600V).

Danfoss is a leading manufacturer of precision mechanical and electrical components, with locations in more than 120 countries.  Danfoss created the VLT name when they introduced the world’s first mass-produced VFD in 1968, and the name has set the standard for high performance quality variable frequency drives ever since.
