The DDS02.1-W025-DS01 is a modular drive controller produced by Bosch Rexroth Indramat within the DDS Drive Controllers series. Designed for cabinet-mounted motion systems, it serves as the closed-loop power stage that regulates three-phase servo motors in automated machinery. By converting command data from higher-level controllers into precisely metered current, it supports accurate velocity and position control in packaging, printing, and material-handling axes. Its modular format also allows it to be combined with related supply and control components in a compact rack, which helps keep multi-axis installations organized inside the cabinet.In operation, the controller exchanges cyclic setpoints and diagnostic messages over the SERCOS interface, enabling deterministic fiber-optic communication with CNC or PLC masters. Thermal management relies on internal air cooling, so a built-in fan moves cabinet air across the heat sink without requiring external ducting. The power section supports a continuous output of 25 A, allowing medium-frame servo motors to sustain rated torque during normal duty. Rotor position is returned through digital servo feedback, which supplies high-resolution angle data for commutation and closed-loop motion control. This combination supports stable speed regulation and responsive axis behavior during repetitive machine cycles.The unit belongs to Line 02 and uses the corresponding backplane layout for this controller family. It carries Function ID 01, which identifies the fixed option set assigned to this version of the drive, and the unit is Version 1 in the product line. Classified as a Digital AC Servo Drive Controller, it generates phase-modulated output through PWM transistor bridges to operate compatible synchronous or induction servo motors across a broad speed range. Installation is intended for a protected control cabinet, where the drive can operate alongside matching supply modules and auxiliary cards. The controller layout supports orderly integration of power, feedback, and communication connections within multi-axis automation systems.
