Product Description:

The DDS02.1-W100-DL04-01-FW is a digital AC servo drive controller built by Bosch Rexroth Indramat as part of the DDS Drive Controllers series. Designed for panel-mounted installation, it serves as the power and control link between a supply module and a synchronous or induction servo motor. In an industrial automation system, the unit converts motion commands from a higher-level control into regulated current so the connected axis can achieve the required torque, speed, and position with repeatable performance. Its role is to support closed-loop motion by combining current regulation with motor feedback processing inside a compact cabinet-mounted drive package.

The controller uses single-axis position control for one motor axis, and heat is removed by internal air cooling that circulates cabinet air across the power section. The output stage is rated for a continuous current of 100 A, making it suitable for medium-to-large servomotors in applications that require sustained drive capability. The enclosure has an IP20 rating, so the unit is intended for protected installation inside an electrical cabinet rather than for exposed machine mounting. Reliable operation is permitted in ambient temperatures from 0 to 45 °C, which fits normal factory conditions where the cabinet environment is controlled by standard ventilation.

Motor feedback is handled through digital servo feedback, allowing the controller to read encoder signals for closed-loop speed and position control. The unit can be stored or transported at temperatures from -30 to 85 °C, which supports handling and warehousing before installation. Installation is permitted at elevations up to 1000 m above sea level without cooling adjustment, so the drive fits typical plant locations without special derating. The controller uses separate firmware for application-specific operation, which allows the drive functions to be matched to the intended control task.
