Product Description:

The DDS02.1-W050-DL01-01-FW is a digital servo drive controller manufactured by Bosch Rexroth Indramat and assigned to the DDS Drive Controllers series. In an automation rack, this unit produces regulated three-phase output for synchronous or induction servomotors, coordinating torque, speed, and position loops under command from a higher-level PLC in standalone or networked machine sections. The device acts as a closed-loop axis drive, translating motion commands into precise current vectors so that machinery such as packaging stations, printing lines, or material-handling gantries achieves repeatable movement during indexing, positioning, and speed-controlled operation.

Continuous output capacity reaches 50 A of rated current, allowing the connected motor to deliver its full design torque without overheating the drive stage. The controller expels heat through air drawn from inside the control cabinet, so the enclosure must provide clear airflow paths around the heat sink. Its terminal block and logic circuits sit behind a housing rated IP20; this level helps prevent accidental finger contact with live parts but still requires an enclosed panel in dusty or wet locations. The electronics operate from 0 to 45 °C, supporting machine rooms where the temperature is controlled but may still fluctuate. Position feedback is processed as digital servo feedback, enabling high-resolution commutation and automatic parameter recognition for compatible Indramat motors during startup and normal closed-loop operation.

The permissible site altitude extends to 1000 m, maintaining cooling margins and dielectric strength without derating at standard atmospheric pressure. When the equipment is stored or shipped, the drive withstands temperatures from -30 to 85 °C, so spare modules can be kept in non-climate-controlled warehouses before installation. Command data arrive through a single-axis position control interface, allowing precise motion of one mechanical axis per module while keeping each amplifier dedicated to its own axis. Because application-specific software resides in removable PROMs, the operational firmware must be ordered as a separate subitem so the hardware can be matched with the required functional package.
