Product Description:

The DDS02.2-W050-BE01-01-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. Mounted inside a control cabinet, it forms the power and control interface between an Indramat supply module and the machine's servo motor, with power conversion and signal processing handled in the same housing. In an industrial automation cell, it generates controlled three-phase output, processes feedback, and communicates with the supervisory PLC to execute position, speed, or torque commands for axes such as pick-and-place gantries, printing rollers, or material-handling stations.

The controller delivers a continuous output of 50 A, allowing it to energize medium-frame motors without derating when acceleration peaks are moderate. Command and diagnostic data are exchanged over a SERCOS interface, so timing is cycle-synchronous and fiber-optic isolation minimizes electrical noise. Heat is removed by air from inside the control cabinet, so cabinet airflow must carry the drive's losses away rather than rely on external fans. For position feedback, the unit interprets digital servo feedback as well as resolver feedback, allowing it to work with Indramat motors equipped with high-resolution encoders and with legacy machines that still use sinusoidal resolvers. This gives the controller flexibility across mixed motor platforms in existing automation equipment.

The unit requires a separate firmware subitem because its control algorithms and parameter sets are stored in removable memory rather than fixed ROM. The controller carries Function ID 01 and is released as Version 2. Within the DDS product structure, it belongs to Line 02, which groups controllers with the same bus voltage, mechanical outline, and connector arrangement. The removable memory arrangement keeps the application software separate from the base controller hardware.
