Product Description:

The DDS03.2-W015-BE45-01-FW belongs to the DDS Drive Controllers series produced by Bosch Rexroth Indramat. As a digital AC servo drive controller, it converts incoming DC-link energy into controlled three-phase output for a matched motor while monitoring feedback loops. Within an automation cell, the unit coordinates motion commands from a PLC or CNC so that axes accelerate, decelerate, and hold position with consistent precision. This operating role makes it suitable for closed-loop motion tasks where stable torque delivery and accurate axis response are required. It can also be used in systems that require coordinated starts, stops, and holding behavior across multiple servo axes.

This controller exchanges real-time data over the SERCOS interface, allowing deterministic network timing between multiple drives and the master. Thermal management is handled by internal air cooling, so the unit draws cabinet air across its heat sink without requiring external fans. Because cooling air is taken from the cabinet, the enclosure should provide clear airflow around the drive. Component surfaces are rated at IP20, so the drive is finger-safe but must be installed in a protected enclosure. The power stage is designed for a continuous output of 15 A, giving adequate headroom for medium-torque synchronous or induction motors in machine tools or packaging lines. Reliable operation is permitted in ambient temperatures from 0 to 45 °C.

Installation height can reach 1000 m without current reduction, supporting plants situated well above sea level. Position accuracy is maintained through digital servo feedback and resolver feedback, letting machine builders choose between high-resolution encoders or rugged resolver sensors on each axis. This feedback flexibility supports motor pairings that favor either high resolution or robust signal transmission. When the equipment is powered down, electronics remain within tolerance during storage or transit from -30 to 85 °C. The controller is part of Line 03 and uses Version 2.
