Product Description:

The DDS02.2-W015-BE84-01-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat in the DDS Drive Controllers series. The unit regulates three-phase servo motors by monitoring current, velocity, and position loops and delivers command and diagnostic data to higher-level motion processors. Within an automation cell, it forms the power stage between a motion controller and the mechanical axis, supplying controlled current and collecting feedback signals for closed-loop positioning.

The drive exchanges real-time data with the motion controller through the SERCOS interface, so command and status wiring is carried on a single fiber-optic ring. Its continuous output capacity is 15 A, which is the maximum phase current the connected motor can receive without overloading the power section. Component heat is removed by air drawn from inside the control cabinet, which eliminates the need for an external fan and requires adequate cross-flow inside the enclosure. The housing is classified as IP20, so fingers and debris larger than 12 mm are blocked, but the cabinet must provide additional ingress protection. Operation is limited to 0 °C and 45 °C, so additional cooling or derating is required when the ambient temperature exceeds this range. Position loops can be closed with digital servo feedback or resolver feedback, allowing the same controller to work with legacy or high-resolution encoder systems.

Installation is limited to 1000 m above sea level because higher altitudes reduce air density and may require current derating. When the controller is powered down, it can be stored or shipped between -30 °C and 85 °C, which protects passive components during transport and storage. The controller requires a separately ordered firmware subitem so the software matches the application and the Line 02, Version 2, and Function ID version 01 identifiers.
