Product Description:

The DDS02.1-W050-DS50-01-FW belongs to the DDS Drive Controllers series produced by Bosch Rexroth Indramat. As a servo drive controller, it supplies regulated power and closed-loop control to matched Indramat motors within modular automation racks. In these systems, it serves as the link between the common DC bus and the motor so the axis can respond to commanded speed and position changes during continuous machine cycles. By linking motion axes to a common DC bus, the unit simplifies cabinet wiring while supporting coordinated motion in material-handling machines, printing lines, and gantry systems.

A fiber-optic SERCOS interface handles deterministic real-time communication so drive data remains synchronized with the master PLC. The power section is rated for a continuous output of 50 A, giving the drive enough current capacity for medium-inertia motors that experience rapid load changes. Thermal management relies on internal air cooling, with airflow drawn from inside the control cabinet rather than from an external blower mounted on the module. Rotor feedback is processed through digital servo feedback, enabling high-resolution position capture without analog conversion errors. This feedback path supports precise commutation and stable axis control across changing operating conditions. The device is classified as a Digital AC Servo Drive Controller, so current loops, commutation, and diagnostic functions are handled inside the unit.

The controller uses fixed identification values for platform matching across the DDS range. Its Function ID is 01, which places it in a specific control group within the product line. The product is part of Line 02 and is marked as Version 1. Those identifiers separate this unit from DDS controllers with other function groups or design revisions and help keep parameter selection aligned with the controller type.
