Product Description:

The DDS02.1-W015-RA02-01 drive controller is produced by Bosch Rexroth Indramat and belongs to the DDS Drive Controllers series. It is a digital AC servo drive controller for compatible Indramat motors in multi-axis machinery, providing regulated current and speed control from the same cabinet. In assembly lines, packaging machines, and printing stations, the unit responds to command signals from a central motion controller to coordinate high-response servo axes. This cabinet-mounted design keeps the drive electronics close to the motor connections and supports precise motion control for repeated positioning cycles.

Its control side uses an analog interface, so speed or torque setpoints arrive as ±10 V signals that the internal processor converts into pulse-width-modulated phase currents. The power section provides up to 15 A of continuous output, which is the maximum continuous RMS phase current available to the connected motor windings. Thermal management relies on internal air cooling, so cabinet airflow removes switching losses without a separate external fan module. Rotor position is returned through resolver feedback, allowing stable motor commutation and consistent speed regulation at low speed and during standstill. Because the command channel is analog and the feedback device is a resolver, the controller fits systems built around those signal types.

Configuration data is encoded in the type code rather than presented as a user-selectable option list. The unit carries Function ID 01, which assigns the parameter group used by this controller. It belongs to Line 02, which uses the mounting layout and component spacing associated with second-generation DDS units. The product is Version 1, indicating the first mechanical and electrical release for this current class. These identifiers distinguish the controller from DDS variants that use other command channels, feedback arrangements, or output classes.
