Product Description:

The DDS02.2-W100-BE37-01-FW belongs to the DDS Drive Controllers series produced by Bosch Rexroth Indramat. As a digital AC servo drive controller, it supplies regulated power to synchronous or induction motors used in automated machinery. It coordinates torque and speed commands received from a higher-level control system over fiber-optic links. By closing current and velocity loops locally, the unit reduces processing demand on the central PLC and helps the axis react more quickly to changing loads or motion commands. That arrangement keeps core motion functions inside the drive, which supports stable speed regulation during repetitive starts, stops, and direction changes.

Communication with the host controller is handled through a SERCOS interface, which transmits real-time setpoints and feedback with deterministic timing. The unit delivers a continuous output current of 100 A, so connected motors and cabling must be sized for the available current. A protection rating of IP20 indicates finger-safe construction, but the controller still requires installation inside a cabinet or other enclosure. Heat is removed by internal air cooling, and the permitted ambient temperature range is 0 to 45 °C for normal operation. The controller is part of Line 02 and uses Function ID version 01, which identifies this variant within the DDS platform.

Motor transducers can be connected as digital servo feedback or resolver feedback, allowing the same drive to support either high-resolution encoder systems or resolver-based feedback loops without extra interface cards. This flexibility helps the controller work with a broader range of compatible motors. It also allows the same cabinet layout to be used with different motor feedback types when the application requires it. Installation heights up to 1000 m do not require current derating in standard plant environments. When the equipment is powered down, the electronics can be stored from -30 to 85 °C during transport or warehouse storage.
