Product Description:

The DDS03.1-W030-RS01-03-FW is a drive controller produced by Bosch Rexroth Indramat within the DDS Drive Controllers series. Designed to regulate synchronous and asynchronous servo motors in automated machinery, the unit converts commanded setpoints from a motion controller into precisely metered three-phase output. In production lines, packaging systems, and material-handling axes, the controller maintains loop accuracy, protects the motor, and interfaces with higher-level PLCs through its integrated fieldbus hardware. By integrating power electronics and communication circuitry in a single module, it reduces panel wiring in distributed multi-axis installations and supports compact control cabinet layouts.

Motion commands reach the controller through a SERCOS interface, so cyclic setpoints and diagnostics share fiber-optic wiring with neighboring drives. The power stage is rated for up to 30 A of continuous output current, allowing direct operation of mid-frame Indramat servo motors without an external booster. Position and velocity loops close on a connected motor encoder that supplies resolver feedback. This analog sensor provides rotor angle feedback to the drive during operation. Thermal management relies on air from inside the control cabinet, and the built-in fan draws enclosure air across the heat sink without additional ducting. The unit carries Function ID 01.

The product is part of Line 03, which matches the bus-bar and terminal layout used in that design line. The unit is Version 1, so its connector pinouts and diagnostics follow that release. The firmware must be ordered as a separate subitem. Its classification as a digital AC servo drive controller means signal processing, regulation, and fault logging occur in software rather than analog circuitry. This arrangement supports consistent motor control behavior across automated motion applications that use the DDS platform.
