Decentralised drives cut commissioning time

April 2003 Motion Control & Drives

Danfoss Drives has developed a new range of individual and integrated drive solutions (incorporating distributed control) that feature rugged construction to withstand challenging application environments, while reducing downtime and service-time to a minimum.

"These solutions are particularly well suited to conveyor applications in the automotive, food and beverage and materials handling industries," explains Mick Baugh, Danfoss business unit manager, motion control and flow. "They are available with a power range of 0,37 to 7,5 kW three-phase 380-480 V a.c., and support RS485, Profibus, DeviceNet or AS-i bus communication protocols. Decentral individual drive solutions can be used on any standard AC motor, or can be mounted on the wall or application equipment."

This includes the VLT Decentral FCD 300 and DMS 300 Decentral motor switch, both with IP66 protection for detergent or high-pressure cleaning. The DMS 300 incorporates integrated soft-start and soft-stop functionality for applications where fixed speed operation is required in either the forward or reverse direction. Decentral integrated drive solutions consist of an optimally matched variable frequency power converter and high-efficiency motor that offer minimum mounting and adaptation costs. They include the VLT DriveMotor FCM 300 with IP55 protection (IP56and IP66 optional) and Eta Solution series K. The FCM 300 features a preset adaptation between the drive and motor for precise, energy efficient control. The Eta Solution series K are compact solutions with infinitely variable speed control. Both are compliant to EMC standards. Decentralised (distributed) motion control meets the ever-growing demands for maximum installation flexibility, and reduced lead-time and commissioning of industrial machinery.

Distributed control lowers installation costs, makes cabinet space nearly obsolete, and significantly reduces cabling expenses. It also facilitates quick and easy service, retrofitting and upgrading. Additional features include improved utilisation of narrow space and easy reconfiguration of production flow.
