Product Description:

The DDS02.1-W100-DS11-00 is a servo drive module developed by Bosch Rexroth Indramat for multi-axis automation. It supplies regulated three-phase power to synchronous or induction servo motors and exchanges real-time motion data with upper-level control hardware. Within an industrial cell, the unit occupies a single slot in a rack and converts DC-link energy into controlled motor phase voltage for accurate velocity and torque control. The controller is intended for cabinet installation in production machinery where several axes share a common DC bus. By modulating motor voltage in real time, it supports smooth acceleration, controlled deceleration, and steady speed regulation during repeated machine cycles.

Communication with the motion coordinator relies on the SERCOS interface, which carries cyclic position commands and diagnostic data over a fiber-optic ring. The power stage can deliver up to 100 A of continuous output. Heat is removed through internal air cooling, so cabinet air passes over the rear heat sink instead of requiring external ducting. Rotor position feedback arrives as digital servo feedback, allowing closed-loop control without analog drift. Tuning of the current loop remains stable even when motor inductance differs from nominal values, which helps the drive maintain predictable response across compatible motor combinations.

The unit is part of Line 02, which matches the connector orientation and keying used by other second-generation modules in this platform. It is built as Version 1, and the controller combines power electronics, signal processing, and protective functions in one enclosure as a digital AC servo drive controller. Mounting holes and bus connector spacing follow the pattern used by the DDS Drive Controllers series, so the module fits standard rack positions used by this product line. The front-mounted module format keeps the control connections accessible from the cabinet front and keeps shared bus interfaces aligned with adjacent axes.
