Product Description:

The DDS03.2-W030-BE31-01-FW is a digital AC servo drive controller developed by Bosch Rexroth Indramat and part of the DDS Drive Controllers series. In an automation cell, the unit supplies regulated three-phase power to synchronous or asynchronous servomotors, closes the velocity and position loops through feedback, and exchanges process data with higher-level motion platforms. It is intended for modular rack-based drive systems where multiple axes must operate with coordinated response and consistent control behavior. Because it fits the DIAX04 rack format, the controller supports compact multi-axis layouts without requiring separate mains wiring for each axis.

A SERCOS interface port transfers real-time setpoints and diagnostics over a fiber-optic ring, eliminating analog wiring. The power stage delivers a continuous 30 A of motor current, which suits mid-frame servomotors used for positioning and speed control. Thermal energy is removed by internal control cabinet air cooling, so the drive relies on cabinet airflow rather than an onboard fan. Component ingress protection is limited to IP20, which means the unit is intended for installation inside a closed cabinet. Position information is accepted through digital servo feedback or resolver feedback, allowing compatibility with either feedback method without an extra interface card.

The controller operates from 0 to 45 °C, allowing continuous use within the stated ambient range. When powered down, it withstands storage temperatures from -30 to 85 °C without damage to internal components. Reliable operation is permitted up to 1000 m above sea level, after which current capability must be reduced to limit thermal loading. The unit is marked as Version 2, and the separate 01 function ID identifies the control configuration used by this model. These operating limits should be matched with enclosure ventilation and site altitude during system design.
