Product Description:

The DDS02.2-W050-BE85-01-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat within the DDS Drive Controllers series. As a compact axis module, it supplies and regulates three-phase servomotors in automated machinery, providing closed-loop current and velocity control between the machine motion section and a higher-level CNC or PLC. It is intended for mounting in multi-axis drive racks used in packaging, printing, and machine-tool installations. In this role, the controller links the rack power section to the motor so commanded motion can be converted into regulated torque and speed during repeated machine cycles.

It communicates with the system control layer through a SERCOS interface, a fiber-optic link that carries real-time motion commands and status data with deterministic timing. The unit can deliver up to 50 A of continuous output current, so it can drive medium-power Indramat synchronous and asynchronous motors without an external amplifier stage. Thermal management relies on air drawn from inside the control cabinet, which means the module uses cabinet airflow rather than a separate blower. For position feedback, it accepts digital servo feedback for high-resolution encoder signals, and it also supports resolver feedback for applications that use an analog feedback device in higher-temperature operating areas. This combination of communication, current capacity, cooling method, and feedback support allows the controller to fit a wide range of axis arrangements within the DDS platform.

Within the modular DDS platform, the controller belongs to Line 02 and is identified as Version 2. The application-specific behavior is set by Function ID 01, which fixes the operating profile used by this controller. The control code resides on plug-in memory, so the stored data can be matched to the intended application without rewiring the drive. This layout separates the drive electronics from the stored control data and keeps the module aligned with the operating structure used by the DDS series.
