Product Description:

The DDS02.1-W025-DA01-01-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. This device supplies regulated three-phase power to synchronous and induction servo motors and interprets feedback for closed-loop positioning within factory automation cells. It mounts inside a control cabinet and links to higher-level PLCs as part of coordinated motion axes used in packaging machines, material handling systems, and machining centers. In operation, it converts command values into controlled motor current so the connected axis can maintain stable speed and position during repeated machine cycles.

The controller accepts motion commands through its analog interface, allowing ±10 V speed or torque references to be fed directly from a master PLC. To maintain thermal performance, it relies on internal air cooling, meaning cabinet air is drawn across the heat sink rather than using an external blower. The power section is sized for a continuous output of 25 A, so it can drive medium-frame servo motors without derating. Position and velocity loops close via digital servo feedback, enabling high-resolution commutation for demanding contouring routines. This unit belongs to Line 02, which groups drive controllers that share the same mechanical dimensions and connector positions.

As a modular product, the DDS02.1-W025-DA01-01-FW is shipped without application code, and its control logic resides in a card whose firmware is supplied as a separate subitem. Drive behavior is set by Function ID 01, a fixed operating profile used for velocity control. Hardware diagnostics and option mapping correspond to Function ID Version 01, so the assigned control functions follow the same version group throughout the unit. The unit is Version 1, and that designation applies to the regulator board, backplane, and power stage used in this drive.
