Product Description:

The DDS02.1-W150-DS46-02-FW is a rack-mountable drive controller built by Bosch Rexroth Indramat for the DDS Drive Controllers series. It converts DC bus power into controlled three-phase output so that synchronous or induction servo motors can follow commanded speed and torque profiles in automated packaging, printing, and material-handling equipment. The controller is intended for cabinet installation in multi-axis systems where several drives share supply hardware. Multiple DDS modules can be lined up on a common busbar, which helps consolidate axis hardware inside a single cabinet. This layout is common in machinery that combines several coordinated axes within one enclosure.

It can deliver up to 150 A of continuous output current, giving enough headroom for high-inertia loads without auxiliary amplifiers. Data exchange with the supervisory PLC uses the SERCOS interface, providing deterministic fiber-optic telegrams for motion and diagnostic information. Heat is removed by air drawn from inside the control cabinet, eliminating external ducting and keeping cooling arrangements simple. The motor’s encoder signals are processed through digital servo feedback, so position and speed information are available directly to the control loop. This combination supports stable regulation during acceleration, steady operation, and deceleration across a wide range of servo applications.

The controller belongs to Line 02, so its DC bus connectors and mounting slots match second-generation DDS power supplies. It is identified as Version 1. The unit is a Digital AC Servo Drive Controller and can operate in a regenerative rack to return excess kinetic energy to the supply. That arrangement is useful in applications with frequent braking or reversing because returned energy can be handled within the rack instead of being dissipated only at the axis. Its rack format also helps keep adjacent supply and control modules in an organized layout.
