Product Description

The DDS02.2-W050-BE75-02-FW is a Bosch Rexroth drive controller. It belongs to the DDS product line. DDS controllers are designed to either dissipate heat inside or outside the cabinet. Controllers that dissipate heat inside the cabinet need to be mounted in large cabinets. If large cabinets are not available then air conditioning is required. Controllers that dissipate heat outside the cabinet can be mounted in smaller cabinets. The DDS02.2-W050-BE75-02-FW is designed for heat technology i.e. heat dissipation inside the cabinet. The recommended temperature of air that surrounds a working controller is 0 to 45 degrees Celsius. The controller output derates linearly between 45 and 55 degrees Celsius. The maximum derating of 20% is reached at 55 degrees Celsius. Bosch not permit operation of the DDS02.2-W050-BE75-02-FW controller at temperatures exceeding 55 degrees Celsius.

The maximum recommended altitude for controller operation is 1000 meters. The output of the DDS02.2-W050-BE75-02-FW derates non-linearly between 1000 and 5000 meters. The maximum derating of 35% due to high altitudes occurs at 5000 meters. Bosch does not permit controller operation at altitudes that exceed 5000 meters. Rated output of the DDS02.2-W050-BE75-02-FW controller is 50 Amps. The controller supports SERCOS command communication. Two motor feedback methods are supported including digital servo based feedback and resolver based feedback. The DDS02.2-W050-BE75-02-FW operates at 24 Volts DC input. It only works with regulated DC power supplies. Weight of the controller is approximately 7.5 kilograms. Dimensions of the controller are 355 x 105 x 325 millimeters. The minimum amount of free space recommended in front of a mounted controller is 40 millimeters. The minimum required free space on the top and bottom sides of a mounted controller is 80 millimeters.
