Product Description:

The DDS03.1-W050-DS23-02 is a digital AC servo drive controller produced by Bosch Rexroth Indramat within the DDS Drive Controllers series. Installed in a control cabinet, it converts motion commands from a central PLC into regulated three-phase output for machine axes that require accurate speed and position control. Typical uses include indexing feeders, pick-and-place gantries, and printing cylinders where repeatable motion is necessary during continuous production. The module also slides onto a common DC bus with other DDS units, which supports compact multi-axis layouts and keeps power distribution centralized inside the cabinet.

The controller exchanges real-time setpoints over the SERCOS interface, allowing deterministic communication with the higher-level motion system. A continuous phase current of 50 A is available, so medium-frame motors can be driven through demanding acceleration periods without exceeding the unit’s normal operating capability. Its enclosure has an IP20 rating, which means it is intended for installation inside a protected cabinet rather than in open exposure to dust or moisture. Heat is removed by air from inside the control cabinet, so cabinet ventilation must be maintained to keep internal temperatures stable during operation. Reliable operation is permitted between 0 – 45 °C, which suits most indoor industrial environments and supports steady drive performance across normal production shifts.

Position feedback from the motor is handled as digital servo feedback, allowing the drive to process position and speed information directly for closed-loop control. Installation is permitted up to 1000 m above sea level, which covers the elevation of most manufacturing sites without requiring current reduction. When the equipment is not in service, the unit can be stored between -30 – 85 °C without harming normal component integrity. The controller belongs to line 03 and ships as version 1. This revision status helps keep the unit aligned with the corresponding hardware generation used in the DDS platform.
