Product Description:

The DDS02.1-A100-DS22-01/S002 drive controller is produced by Bosch Rexroth Indramat within the DDS Drive Controllers series. It governs torque, speed, and position loops for servo motors used in automated production lines, packaging equipment, and material-handling stations. By converting PLC commands into precisely modulated three-phase output, it keeps motion sequences synchronized with machine cycle timing. This operating role supports repeatable movement during indexing, transfer, and positioning tasks. It is suited for machines that require coordinated starts, stops, and speed changes across servo-driven axes.

The controller communicates with the higher-level PLC through the SERCOS interface, a fiber-optic fieldbus that transfers real-time setpoints and diagnostic data in a deterministic cycle. A continuous output capability of 100 A allows it to energize medium-frame servomotors, while internal monitoring helps protect the power stage during changing load conditions. Thermal management uses external air cooling, so ambient air from outside the cabinet moves across the heat sink to remove heat. The housing has an IP20 rating, which provides finger-safe protection for live parts but still requires the unit to be mounted inside an enclosure where dust or liquids may be present. Safe operation is permitted from 0 to 45 °C, so cabinet airflow must keep internal temperatures within that range. This arrangement supports stable electrical performance during continuous machine operation.

The position loop relies on digital servo feedback, allowing the drive to process absolute or incremental encoder signals with very low latency. This feedback method supports accurate commutation and stable servo response during acceleration, deceleration, and reversal. Installation altitude is limited to 1000 m above sea level because reduced air density can lower cooling effectiveness. During storage or transport, the electronics withstand temperatures from -30 to 85 °C, which supports temporary placement in unconditioned warehouse spaces. The unit is Version 1, which identifies the product release used for this controller.
