Product Description:
The DDS02.2-W050-BE74-02-FW is a servo drive controller produced by Bosch Rexroth Indramat within the DDS Drive Controllers series. In an automation cell, it links a shared DC bus to an AC servomotor, converting command data and electrical power into precise torque and velocity so that handling axes, packaging stations, or CNC tables follow programmed motion profiles. Closed-loop control lets the drive react quickly to load changes and commanded speed shifts during positioning and continuous-motion tasks. Because the unit is part of a modular rack concept, it can be combined with other DDS modules in multi-axis systems while sharing a common DC bus and uniform diagnostic behavior across the installation.
Data exchange with the PLC occurs over the SERCOS interface, a deterministic fiber-optic ring that transfers setpoints, status words, and parameter data. This communication method supports synchronized motion commands in systems that coordinate multiple axes at the same time. The power stage delivers a continuous phase current of 50 A, matching medium-frame Indramat motors that require sustained torque. The enclosure has an IP20 rating, so the unit is intended for installation inside a protected control cabinet. Full output is supported at ambient temperatures from 0 to 45 °C. Heat is removed by internal air cooling, so cabinet airflow must keep recirculating air within the permitted temperature range.
The feedback port accepts digital servo feedback and resolver feedback, allowing the same controller to operate with newer high-resolution encoder motors as well as legacy resolver-equipped units. This flexibility supports mixed motor configurations within the same machine platform. Non-operating conditions permit storage from -30 to 85 °C without damage to electronic components. Rated performance is specified up to 1000 m above sea level, and higher elevations can reduce cooling capacity because of lower air density. The controller belongs to line 02 and uses second-generation hardware.
