The Bosch R911273699 (DDS02.2-A200-BE76-01-FW) is a DDS series drive controller, compatible with various Bosch industrial motors. Featuring an external heat sink, it guarantees that 80% of heat dispersion occurs outside the cabinet, reducing inside accumulation to only 20%. It measures to 355mm x 325mm x 105mm, excluding the heat sink whose dimensions are 345mm x 160mm x 105mm. A minimum space of 80mm is recommended at the controller's top and bottom, with 40mm needed at the front to ensure unhindered airflow. Performance is optimal within an ambient temperature of 0-45 degrees Celsius and up to 1000m above sea level. The IP20 rating enclosure indicates it's not dust or moisture proof. The relative humidity should not surpass 95%, while the absolute humidity level should remain within 25g/m3. Rated for a 200 Amps output, it favors both resolver and digital servo feedback. The installed SERCOS command communication module uses optical fibers for secure data transfer. Installation and operation should be executed by qualified personnel.
