Product Description:

The DDS02.1-W150-DL20-01-FW is a modular drive controller in the DDS Drive Controllers series from Bosch Rexroth Indramat. Installed on a backplane in the control cabinet, the unit converts shared DC bus voltage into the three-phase output required by a synchronous servo motor. It serves as an axis controller in packaging, printing, and material-handling lines, where speed and position loops must respond quickly between the automation controller and the mechanical load. Because it operates from a common DC bus, it fits multi-axis systems that distribute power from a central supply module. Integrated diagnostic LEDs support status monitoring during operation and cabinet service.

Its communication layer is configured for single-axis position control, so the drive receives incremental moves or absolute position commands directly over the system bus. The power section is rated for 150 A, allowing it to energize medium-to-large Indramat motors during acceleration and regenerative operation. Thermal management uses air from inside the control cabinet, so the enclosure must provide enough airflow to keep the power electronics within their temperature limits. Rotor information returns through digital servo feedback, which sends position, velocity, and diagnostic data over a high-speed serial channel. The unit is part of Line 02, which identifies the second family revision and maintains compatibility with matching supply and bus modules.

The drive uses a modular code scheme, and the control algorithm with its parameter set resides in plug-in firmware. Application software recognizes the unit through Function ID Version 01, and the general hardware release is Version 1. This arrangement helps keep the selected application functions matched to the installed drive features. It also keeps the parameter set and diagnostic tools aligned with the correct control variant.
