Product Description

DKR03.1-W220N-BE48-01-FW is a digital drive controller. It is designed and manufactured by Bosch Rexroth. The controller belongs to the DKR series. Its input voltage rating is 400 to 480 Volts AC. The current output rating is 220 Amps. Bosch has designed the controller to support both resolver feedback and digital servo feedback. As a result, the controller can be used with several servo motors manufactured by Bosch Rexroth. The controller comes with an internal blower for cooling. It has a cold air inlet at the bottom and a hot air outlet at the top of the unit. To ensure these air paths remain unblocked, Bosch recommends a minimum spacing of 80 millimeters on the top and bottom sides of the installed controller. During operation, the drive dissipates energy not only via the air vents at the top of the housing but also via the built-in heatsink. The energy dissipated depends on the load. To correctly dimension the cabinet or cooling equipment, it is necessary to know the accurate energy losses. The recommended ambient temperature for optimal controller operation is 0 to 45 degrees Celsius. The recommended site elevation for optimal controller operation is 0 to 1000 meters. Housing of the controller unit belongs to the IP20 protection category. The controller can be used indoors. However, outdoor use requires controller mounting inside a cabinet that provides suitable environmental protection. Command communication interface on the unit is SERCOS, which is a high-speed communication protocol widely used in industrial automation applications. The physical medium used by SERCOS is fiber optic, which enables use of redundant ring topology for high availability network communication. Weight of the unit is 49 kilograms.
