Product Description:

The DDS02.1-A150-DS03-01 is a digital AC servo drive controller produced by Bosch Rexroth Indramat within the DDS Drive Controllers series. The unit mounts inside a control cabinet and works alongside Indramat power supplies and servo motors to regulate torque, speed, and position in automated machinery. As a drive controller, it receives setpoint data from a PLC or motion processor and converts those commands into controlled three-phase output for synchronous or induction motors in assembly lines, material-handling axes, and packaging equipment.

Communication with higher-level automation systems takes place over the SERCOS interface, a real-time fiber-optic network that supports tightly synchronized multi-axis motion. The drive can deliver up to 150 A of continuous output current, so it pairs with medium- and high-torque motors without external amplifiers. Thermal energy is removed by external air cooling, meaning ambient air is drawn from outside the cabinet through the heat sink rather than recirculated internally. Its housing carries an IP20 protection rating, so live parts are finger-safe but the controller must stay in an enclosure. Reliable operation is permitted at ambient temperatures from 0 to 45 °C, allowing installation on factory floors that are neither refrigerated nor exposed to extreme heat.

Feedback from the motor is processed through digital servo feedback, enabling precise closed-loop current, velocity, and position regulation without additional resolver converters. The electronic design maintains rated performance up to 1000 m above sea level, and during transportation or extended shutdowns the unit tolerates ambient temperatures from -30 to +85 °C. Within the DDS architecture, it belongs to Line 02, and the function package is version 01 for this controller type.
