Product Description:

The Bosch Rexroth Indramat DDS02.1-W025-RS18-00 is a digital AC servo drive controller in the DDS Drive Controllers series. As an automation component, the unit supplies controlled three-phase power to synchronous or induction servo motors so that speed and torque setpoints from a higher-level CNC or PLC are carried out with precision. When combined with a compatible power supply module, it forms a modular axis drive for material handling, printing, and packaging lines. Its closed-loop operation supports responsive motor behavior during acceleration, deceleration, and steady-state motion.

The controller exchanges real-time commands over a SERCOS interface, keeping position and velocity data synchronized on a fiber-optic ring. Its continuous output is 25 A, which is the maximum motor current the power stage can supply without derating. Heat is removed by internal air cooling, so no external blower is required. The housing has an IP20 rating, which makes live parts finger-safe but requires installation inside an enclosed panel. This arrangement suits cabinet-based servo systems where airflow is already available within the enclosure.

The drive operates in ambient temperatures from 0 – 45 °C and can be stored between -30 – 85 °C, allowing it to remain in unconditioned facilities while powered down. Reliable resolver feedback is processed through the signal module, and this channel supplies rotor angle data required for sinusoidal commutation during startup. Installation is permitted up to 1000 m above sea level before current derating applies, and the unit follows DDS line 02 mechanical dimensions so it can slide onto the same mounting rails as companion axes. The standardized form factor helps the controller fit neatly into multi-axis cabinet layouts without requiring a different rail arrangement.
