Product Description:

The DDS03.1-W030-DS29-01 is a digital servo drive controller from Bosch Rexroth Indramat in the DDS Drive Controllers series. It conditions three-phase power and closes the control loop between motion commands and motor response, allowing precise speed and position regulation in automated printing, packaging, and material-handling machinery. Installed in a multi-axis rack with an external supply module, the unit converts higher-level PLC commands into regulated current for compatible Indramat synchronous or asynchronous AC motors and helps maintain stable axis behavior during changing loads. That operating role makes it suitable for synchronized feeding, indexing, and transfer motions where repeatable response is needed across multiple axes.

This controller exchanges cyclic set points and status words over the SERCOS interface, providing deterministic communication for coordinated multi-axis motion. Thermal management uses internal air cooling, and cabinet air passes through the heat sink so no external ducts are required. The power stage is rated for 30 A of continuous output, enabling it to drive medium-frame motors without derating. Position information is processed through digital servo feedback, which supports high-resolution commutation and fast disturbance correction. This allows the connected motor to maintain smooth motion when commanded speed or load changes rapidly. As a Digital AC Servo Drive Controller, it provides field-oriented current regulation, automatic motor parameter recognition, and protective functions against overcurrent, overtemperature, and shorted outputs.

The unit carries Function ID version 01. It is part of Line 03, which uses a common backplane pinout and shared supply bus ratings for this drive platform. This controller is Version 1, so its circuitry and component tolerances match the first production release. The identification scheme also keeps the unit grouped with the correct parameter range for this drive line. It uses the standard diagnostic telegrams and parameter structure for the platform, which helps it fit into established control layouts without requiring custom signal mapping.
