Product Description:

Bosch Rexroth Indramat manufactures the DDS02.2-A100-BE42-03-FW drive unit as part of the DDS Drive Controllers series. The module is a digital AC servo drive controller intended to regulate synchronous or asynchronous servo motors in automated production cells, material-handling axes, and general motion-control stations. Integrated in a multi-axis rack, it supplies closed-loop control commands to a connected drive while receiving position data from feedback devices, thereby forming the core power-conversion layer in an industrial automation hierarchy.

The drive’s continuous output has a ceiling of 100 A, enabling it to energize high-torque servomotors without additional amplification stages. Command and diagnostic data pass over the SERCOS interface, so axis parameters, status words, and real-time setpoints travel deterministically on a fiber-optic ring linking multiple drives to one controller. Thermal regulation relies on air drawn from outside the control cabinet, meaning the unit pulls ambient air directly across its heat sink and requires filtered louvers. Position and velocity loops can be closed with digital servo feedback, allowing absolute or incremental information to be sampled at high resolution. Mechanical and electrical attributes match those of Line 02, placing the model in the second design generation with standardized backplane and connector layouts.

Supplementary motion transducers, such as resolver feedback, can be selected when rugged angle sensing is preferred over optical encoders, and the drive automatically adapts its commutation method to the connected device. The hardware is identified as Version 2, which aligns the gate-driver electronics and diagnostics with later platform updates while remaining compatible with existing rack power supplies. Application-specific functions are provided through separate firmware, and the module uses the same rack format and connection scheme as related units in this platform.
