Product Description:

The DDS02.1-A150-DS48-00-FW drive controller is produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. As a digitally regulated AC servo drive controller, it links a power converter with motion control logic to command synchronous or induction servo motors used in automated handling, packaging, and machining stations. It is intended for cabinet-installed automation systems where multiple axes must respond to coordinated motion commands. By converting fixed mains energy into a variable, precisely timed output, the unit serves as the interface between higher-level PLC sequences and the mechanical axes that carry out programmed movement. This arrangement lets the drive regulate torque, speed, and position within one control system while responding to changing loads during cyclic machine operation.

The controller delivers a continuous output of 150 A, supplying phase current to large torque motors without external boosters. For deterministic communication, it relies on the SERCOS interface, a fiber-optic ring that passes setpoints and feedback in real time for synchronized multi-axis networks. That communication path supports coordinated command timing across linked axes during interpolation and rapid index moves. Thermal management uses air from outside the control cabinet, which helps keep the enclosure temperature stable while sensitive electronics remain isolated from process dust. Motor position and velocity are captured through digital servo feedback, enabling the drive to perform fine loop corrections at high update rates. The unit is part of Line 02 in the DDS architecture.

The drive is Version 1. Control logic resides in detachable ROM packs, so the software can be selected separately without replacing the power stage. Its standardized connector layouts, bus bars, and cooling airflow support integration with matching supply units in the same platform. The layout also suits cabinet systems where a separate supply module distributes DC bus power to several axes. Classified as a Digital AC Servo Drive Controller, it pairs directly with Indramat supply units to form closed-loop axes for demanding positioning tasks.
