Product Description:

The DDS02.1-W150-DS29-02 is a digital AC servo drive controller from Bosch Rexroth Indramat and belongs to the DDS Drive Controllers series. It is intended for cabinet-mounted motion axes, where it conditions three-phase inverter output so connected synchronous or induction motors receive regulated current and speed commands. In automated equipment, the controller links the drive train to higher-level CNC or PLC hardware and supports precise torque control for packaging, material handling, and machine-tool applications. Because current regulation is handled at the drive level, the upstream control can focus on axis coordination and process timing. This arrangement supports responsive starts, stops, and speed changes during repeated machine cycles.

The controller exchanges real-time setpoints and diagnostics over the SERCOS interface, allowing deterministic fiber-optic communication with compatible control hardware. Its power stage is rated for 150 A, so the inverter can drive large servo motors across a switching range of up to 8 kHz without current derating in normal use. Heat from the IGBTs is removed by internal air circulation, and the IP20 enclosure is intended for installation in a protected cabinet with filtered airflow. Continuous operation is permitted from 0 – 45 °C, which suits typical industrial ambient conditions when cabinet ventilation is maintained. Using internal airflow instead of external heat sinks keeps the cooling arrangement inside the enclosure and supports compact panel layouts.

Position and speed feedback are handled through digital servo feedback, allowing encoder signals to reach the control loop with high resolution and low latency. This feedback arrangement supports accurate speed regulation and stable position control during acceleration, dwell, and reversal. Installation is permitted up to 1000 m above sea level without power derating, and storage or transport is allowed from -30 – 85 °C. The drive is part of Line 02, and the unit is Version 1. These identifiers help distinguish the controller within the product range and align it with the correct documentation and parameter structure.
