Product Description:

The DDS02.2-W050-BE31-01-FW is a modular servo drive controller produced by Bosch Rexroth Indramat and assigned to the DDS Drive Controllers series. Installed in a multi-axis rack, it converts DC bus energy from a shared supply into regulated three-phase output for synchronous or induction motors, allowing precise speed and torque control in packaging machines, material-handling gantries, and similar automated equipment. In a shared rack, this arrangement lets one supply section feed multiple axes while each controller regulates its own motor output, helping coordinated motion systems stay compact. The unit is classified as a Digital AC Servo Drive Controller, and this version is listed as design 2.

Field integration is handled through the SERCOS interface, so cyclic position data and parameter sets are exchanged over a fiber-optic ring without additional I/O cabling. The fiber-optic link also helps reduce electrical interference on command transmission inside busy control cabinets. The power stage can continuously supply up to 50 A, a current level suited for medium-frame motors that must accelerate loads quickly while staying within cabinet thermal limits during repeated motion cycles. Position feedback flexibility is provided by digital servo feedback and resolver feedback, so the controller can process either high-resolution encoder data or analog resolver signals selected in software. Thermal management relies on internal air cooling, which moves waste heat into the cabinet airflow and removes the need for a rear heat sink.

The drive uses separately ordered firmware, allowing the control software to match the selected motor and fieldbus profile. This keeps the software package separate from the power section and supports application-specific setup without changing the controller body. Function ID version 01 keeps the command set and diagnostics fixed for this control version. The controller belongs to Line 02, which identifies its design line within the DDS platform.
