Product Description:

The DDS02.1-A050-D is a digital AC servo drive controller developed by Bosch Rexroth Indramat for the DDS Drive Controllers series. In an automated cell, it converts DC-bus energy from a supply module into regulated three-phase power and sends speed and torque commands to a paired servomotor. The closed-loop design lets motion commands from a higher-level PLC be executed with fine resolution, which supports repeatable positioning on indexing tables, packaging axes, and similar equipment. This arrangement helps the drive respond quickly to changing loads while keeping axis motion stable during normal machine cycles.

The controller supplies up to 50 A of continuous output current, which is the maximum steady-state motor load the internal power stage can sustain without derating. Its housing has an IP20 enclosure rating, so it blocks solid objects larger than 12 mm and is intended for installation inside a cabinet. Heat is removed by external air cooling; airflow taken from outside the enclosure passes directly over the heat sink and helps manage temperature when several drives share one rack. Position and velocity are monitored through digital servo feedback, allowing the control electronics to adjust switching patterns and maintain commanded setpoints during load changes. Safe operation is permitted within a 0 to 45 °C operating range, and the controller reaches its stated electrical performance only when that temperature window is maintained.

Site planning must respect a 1000 m maximum installation elevation, because higher altitudes reduce cooling effectiveness and may require current reduction. During transport or warehouse storage, the electronics tolerate a −30 to 85 °C storage range without damage to capacitors or protective coatings. The unit is part of Line 02 and is built as Version 1, which indicates the revision level used for this model. These identifiers help place the controller within the DDS product line and match it to the correct mechanical layout and control configuration.
