DDS02.1-W025-DS04-01

The DDS02.1-W025-DS04-01 from Bosch Rexroth Indramat sits at the heart of the DDS Drive Controllers series, delivering industry-leading performance for motion control applications. This digital intelligent drive controller offers a continuous current rating of 25 A and a peak current capability of 50 A, ensuring reliable power delivery to your most demanding motors. Designed for a DC 300 V bus supply (270–350 V tolerance), it accommodates a wide range of power requirements. Weighing approximately 8 kg, the unit boasts a compact footprint optimized for cabinet installation. With a rugged IP20 protection class enclosure, it provides industry-standard environmental resilience.

At its core, the DDS02.1-W025-DS04-01 employs a digital intelligent drive controller architecture with an integrated SERCOS command interface for high-speed, deterministic communication. The controller supports a variety of Bosch Rexroth 1MB, MKD, MHD, 2AD, and 1MB motors, delivering up to 7.5 kW of rated power depending on the connected motor. Housed in a robust chassis, the drive features an air-cooled thermal management system that maintains optimal component temperatures. Its electronics offer a total current capacity of 200 mA for ±15 V rails and 1100 mA for the +24 V rail, supporting extensive I/O and auxiliary functions. Built to drive cable runs up to 75 m without signal degradation, the controller ensures stable feedback evaluation and precise motion control.

Operational reliability is achieved through a wide ambient operating temperature range of 0 °C to 45 °C, permitting continuous operation without derating in standard industrial environments. The drive’s IP20-rated enclosure, combined with required grounding provisions, safeguards internal components from electrical noise and potential faults. Designed for control cabinet installation, it thrives in humidity levels from 10% to 95% RH and at altitudes up to 1000 m. The maximum supported motor cable length of 75 m affords installation flexibility, while the unit’s integrated cooling fan and heat-dissipating design minimize maintenance intervals and reduce downtime.

Integration of the DDS02.1-W025-DS04-01 is seamless with existing Bosch Rexroth automation architectures, providing straightforward slot-based expansion via its U1 SERCOS fiber-optic interface and U2 high-resolution encoder interface. Its compatibility with common bus voltages and motor types makes it ideal for robotics, CNC machine tools, packaging systems, and high-precision printing machinery. Engineers will appreciate the controller’s plug-and-play mounting in control cabinets and its compliance with standard grounding and installation practices. With its blend of power density, advanced communication, and environmental resilience, this drive controller enhances performance across a broad spectrum of industrial automation applications.
