Product Description:
The DDS02.1-W015-RS03-03-FW drive controller is manufactured by Bosch Rexroth Indramat and belongs to the DDS Drive Controllers series. As a digital AC servo drive controller, it regulates current, velocity, and position for compatible servo motors in automated production machinery and material-handling cells. Installed inside a control cabinet, it acts as the axis module that receives commands from motion processors and supplies controlled three-phase power to the motor for precise closed-loop motion in multi-axis systems. In a coordinated machine, the unit serves as the power and control stage for one motor axis while the higher-level controller manages the overall motion sequence.
Communication with higher-level control is handled through the SERCOS interface, a fiber-optic ring that transfers cyclic setpoints and status data with deterministic timing. The power stage is rated for a continuous output of 15 A, so it can drive motors that require moderate continuous torque without oversizing the supply. An IP20 housing permits cabinet mounting where protection is provided by the enclosure rather than by the drive itself. Heat is removed by internal air cooling, so cabinet airflow passes through the heat sink instead of relying on a separate external blower. The unit operates in ambient temperatures from 0 to 45 °C, which suits most factory electrical enclosures that maintain controlled indoor conditions.
The maximum mounting height is 1000 m above sea level, and higher elevations may require derating. Motor position feedback is processed through resolver feedback, which uses analog angle sensing that resists electrical noise in industrial environments. Storage and transport are permitted from -30 to 85 °C, allowing the controller to tolerate typical warehouse and shipping conditions before installation. The controller is part of Line 02 and uses Version 1 hardware for this platform generation. This version placement helps match the unit with the appropriate power supplies and auxiliary cards used in the same generation.
