Product Description:

The DDS03.2-W050-BE32-01-FW is a digital AC servo drive controller created by Bosch Rexroth Indramat for the DDS Drive Controllers series. In an automation cell, it sits between the DC bus supply and a servo motor, converting command words from the machine controller into regulated phase currents. This role gives the connected axis the torque and speed control needed for coordinated motion in packaging, material handling, or printing equipment. It can also be used where several axes must share motion commands and follow synchronized machine timing.

Real-time communication to higher-level controls is handled through the SERCOS interface, which supports fiber-optic cabling and deterministic timing. The power electronics furnish a continuous output of 50 A, allowing reliable acceleration of mid-frame synchronous motors. Thermal energy is removed by internal air cooling; cabinet air passes over the heat sink so no separate fan tray is required. A protection class of IP20 means live parts are finger-safe, but the device must remain inside a clean control panel. The controller maintains rated accuracy and service life within an ambient span of 0–45 °C. Position data from motors equipped with digital servo feedback is processed directly by the control loop, which supports fine velocity regulation without added interface modules.

For legacy axes, the electronics can also decode resolver feedback, which broadens motor compatibility within mixed installations. Installation is approved up to 1000 m elevation without output derating, so standard plant altitudes do not require reduced performance. Components withstand storage or transport temperatures from -30 to 85 °C, helping protect the circuitry when the unit is moved or kept in an unpowered warehouse. The drive is part of Line 03 and Version 2, and it carries Function ID 01 within the DDS range. This identification separates it from other modules in the rack system and helps match the controller to the intended motor and operating setup.
