Product Description:

The DDS02.1-W150-RS01-01 is a digital AC servo drive controller produced by Bosch Rexroth Indramat and positioned within the DDS Drive Controllers series. Intended for multi-axis motion platforms in machining centers, packaging lines, and material-handling cells, the unit converts real-time command data from a host controller into regulated current and voltage for connected servo motors. By coordinating feedback and power modules, it serves as the central control element in closed-loop industrial automation systems that demand accurate velocity, torque, and position control. In a typical installation, it receives motion commands from a higher-level controller and adjusts motor response to support coordinated starts, stops, and speed changes across linked machine functions.

The controller supplies up to 150 A of continuous output current, permitting operation of medium- to high-inertia motors without saturation during acceleration peaks. The enclosure is rated IP20, so the device must be mounted inside a control cabinet to prevent direct contact with live conductors. Heat generated by the power electronics is removed through air cooling inside the cabinet, which avoids the need for an external blower. Deterministic networked motion is enabled by the SERCOS interface, which carries setpoints, diagnostics, and synchronization data over fiber-optic links. Fiber-optic communication also helps reduce the effect of electrical noise from nearby power equipment. Reliable operation is supported within an ambient range of 0 to 45 °C, matching the conditions of most climate-controlled production areas.

When paired with motors that provide resolver feedback, the drive closes its current and velocity loops every cycle using rotor position data. Installation altitude is limited to 1000 m because reduced air density above that height can lower cooling performance. For storage, the electronics tolerate temperatures from -30 to 85 °C, helping protect internal components during transport or long periods out of service. This storage range is also useful when equipment is kept in unheated warehouse spaces before installation. The unit is part of Line 02 in the DDS product family.
