Product Description:

The DDS02.1-W050-DS23-03 is a digital AC servo drive controller produced by Bosch Rexroth Indramat within the DDS Drive Controllers series. Designed for multi-axis automation systems, the unit links a regulated DC supply to a synchronous or asynchronous servo motor and modulates current to achieve commanded torque and velocity profiles. In factory machinery, it forms the interface between motion commands issued by the PLC and the motor windings, translating control signals and return data into the electrical output needed for closed-loop motion. This arrangement allows the drive to support accurate speed regulation and responsive axis behavior during repeated operating cycles.

Communication with higher-level motion controllers occurs through the SERCOS interface, a fiber-optic ring that carries cyclic setpoints and diagnostic data. The drive can deliver up to 50 A of continuous output current, so associated wiring and protection devices must be sized for that load. Its enclosure is rated IP20, which provides finger-safe protection but does not protect against water, so the unit must be installed inside a closed cabinet. Thermal management relies on air from inside the control cabinet, and the airflow path must remain unobstructed for stable heat removal during operation. Reliable operation is permitted within an ambient range of 0 to 45 °C, allowing normal use in typical industrial enclosures.

Motor position is evaluated through digital servo feedback, allowing the controller to close high-bandwidth loops without external converters. Installation sites may be located up to 1000 m above sea level, where standard cooling and insulation conditions remain acceptable. During storage, the electronics can withstand temperatures from -30 to 85 °C without damage to capacitors or optical components. The unit is Version 1 in Line 02, which identifies its revision within the DDS platform. This version marking helps distinguish the drive from other revisions that use different internal layouts.
