Product Description:

The DDS02.1-W025-DS01 is a drive controller manufactured by Bosch Rexroth Indramat and supplied within the DDS Drive Controllers series. It is a digital AC servo drive controller intended to regulate torque, speed, and position of compatible Indramat servo motors in automated production lines, material-handling stations, and assembly cells. By closing the control loop between the servo motor and the higher-level motion processor, it supplies the regulated power required for dynamic axis movement while occupying a single slot in a multi-axis rack.

This controller communicates with the main motion system over the SERCOS interface, allowing deterministic cyclic data exchange for tightly synchronized drives. A continuous output of 25 A is available to the connected motor windings, so sizing calculations can be based on that current ceiling rather than peak values. Heat produced by the power electronics is removed by internal air cooling; air is pulled from inside the control cabinet and passed across the heatsink without relying on external ducts. Command processing is mapped by Function ID 01, a fixed firmware block that defines parameter structure and allowable telegrams. Rotor position is returned through digital servo feedback, enabling high-resolution velocity and position control without analog conversion delays.

Within the controller family it belongs to Line 02, which establishes mechanical dimensions and connector layout for straightforward replacement with units of the same line. Firmware and hardware revisions classified as Version 1 determine the exact microprocessor platform and memory allocation used during commissioning. The industrial pedigree of Bosch Rexroth Indramat ensures spare units follow identical interchange codes, and the controller’s membership in the DDS Drive Controllers series guarantees compatibility with existing rack power supplies, bus modules, and diagnostic tools deployed across modular automation cabinets.
