Product Description:

The DDS02.1-W100-DG01-00 is produced by Bosch Rexroth Indramat as part of the DDS Drive Controllers series. Delivered as a digital AC servo drive controller, it converts high-level motion commands into three-phase power for coordinated motor operation. Within automated cells, the unit supplies regulated current and voltage so that position loops close accurately and cycle times remain repeatable. This lets the controller manage acceleration, steady-speed running, and stopping within a closed-loop axis system. Its compact format lets it mount in multi-axis racks where thermal and electrical compatibility with other DDS modules is important.

It uses internal air cooling drawn directly from the control cabinet, so the cabinet fan must provide constant airflow across its heatsink. The power stage can deliver 100 A, allowing the drive to energize medium-to-high torque motors without current derating. An IP20 housing protects live parts against finger contact and limits dust ingress, making the unit suitable for installation behind a panel rather than on an open machine frame. Electronics operate reliably between 0 to 45 °C, matching typical enclosure climates, and performance remains unchanged up to 1000 m above sea level, where reduced air density only slightly affects heat transfer. Because cooling air is taken from the cabinet interior, enclosure temperature directly affects thermal margin during continuous duty. The unit is Version 1.

Position verification comes from digital servo feedback, so compatible motors must carry Indramat digital encoders. This feedback method sends rotor position data directly to the controller for stable speed and position regulation. When powered down, the unit tolerates ambient extremes between -30 to +85 °C, which supports storage in unconditioned warehouses. The unit carries Function ID 01, and it belongs to Line 02. These identifiers set the available control behavior and place the drive within the second DDS design line.
