Product Description:

The DDS02.1-W025-DS03-02-FW is a digital AC servo drive controller built by Bosch Rexroth Indramat for the DDS Drive Controllers series. The unit regulates three-phase servo motors by modulating current and velocity loops, allowing precise position control in automated assembly lines, packaging stations, and material-handling axes. It functions as the central power stage between higher-level motion controllers and the servomotor, converting DC-bus energy into controlled three-phase outputs while exchanging real-time status data.

Communication with the motion network is carried over a SERCOS interface, so the drive transmits position words and diagnostic bits within a deterministic optical ring. The continuous motor phase current is limited to 25 A, which sets the sizing range for compatible motors and peripheral wiring. Thermal energy is removed by internal air cooling, meaning cabinet airflow passes through the unit without requiring external heat sinks. Component ingress protection is classified as IP20, which indicates finger-safe terminals but no dust sealing. Position feedback is processed via digital servo feedback, allowing high-resolution encoder data to synchronize torque production. The drive belongs to Line 02 and is released as Version 1.

For reliable operation in plant equipment, the controller maintains full performance across an ambient span of 0 – 45 °C and at installation heights up to 1000 m above sea level without derating. When machinery is stored or shipped, internal components tolerate temperatures from -30 – 85 °C, helping protect the unit during transport and storage. The controller uses firmware ordered separately, while application-specific parameter sets reside in flash memory on a plug-in module.
