The DDS02.1-A150-DA07-02 is a drive controller manufactured by Bosch Rexroth Indramat for the DDS Drive Controllers series. As a digital AC servo drive controller, it regulates power delivery and closed-loop motion for synchronous motors in automated machinery. It converts command values into controlled motor current so the connected axis can accelerate, run, and hold speed with consistent response. This makes the unit suitable for machine functions that depend on coordinated servo movement without separate analog amplifier hardware.This model exchanges command and status data through an embedded analog interface, making it suitable for motion systems that still rely on voltage or current reference signals. A continuous output capability of 150 A allows the inverter stage to operate large-frame servomotors without thermal derating during sustained demand. Heat generated in the IGBT bridge is removed by air from outside the control cabinet, so warm exhaust does not build up around nearby electronics inside the enclosure. Rotor position and speed are handled through digital servo feedback, which supports accurate torque regulation and stable response during rapid load changes. The control platform processes feedback signals internally to keep current and speed regulation responsive.The controller belongs to line designation 02 and is supplied in hardware version 1. These identifiers place the unit within a specific DDS product line and indicate the hardware generation used for this model. Internal regulation routines manage velocity control, current control, and diagnostics at high sampling rates, which helps the drive maintain smooth servo behavior during indexing and positioning tasks. It can operate in systems that use analog command structures while maintaining digital closed-loop motor control.
