R911272287
The R911272287 (DDS03.1-W050-RS01-03-FW) is a basic unit for DDS digital controllers, developed by Bosch Rexroth Indramat. Engineered for versatility, the modular design of these controllers allows them to be tailored to a wide array of specific user needs. Both hardware and software (firmware) of the basic unit can be customised. The R911272287 (DDS03.1-W050-RS01-03-FW) model employs heat technology for cooling, using internal heat dispersal within the controller cabinet. While this may necessitate larger cabinets or air conditioning for adequate heat management, this variant requires less installation effort compared to alternative cooling methods.
Although DDS/controllers are capable of working from 0 to 45 degrees Celsius, optimal operation is achieved under specific conditions. For instance, the permissible maximum relative humidity is 95%, the absolute humidity should not exceed 25 g/m3, and the installation elevation should not surpass 1000 meters. With the IP20 protection class, this 50 Amp rated-output controller predominantly supports resolver-based feedback. Additionally, the unit is provided with a SERCOS-supportive command communication module that is flexible based on user requirements. The firmware, however, must be ordered separately. Weighing around 5.5 kilograms, it is advised that the controller be installed by trained professionals to ensure peak performance.
