The Bosch Rexroth MPN R911277221 (DKR02.1-W300Z-BE11-02-FW) is a drive controller designed for integration in automation applications such as machine tools, printing machines, and handling systems. The controller complies with IP20 protection and requires installation in a dust-free, closed control cabinet with at least IP54 rating. It features a power rectifier, five PCI slots, and a DSS 02.1M command interface card for indirect position detection. Communication with AC motors is supported via optical fiber cables and the SERCOS interface. The unit supports digital servo and resolver feedback, weighs 104 kg, and is rated for a nominal current of approximately 300A. Operating temperature range is +5°C to +45°C, with a maximum installation altitude of 1000 meters above sea level. Maximum braking energy is specified at 240 kWs, and cooling is achieved using a 24VDC blower. Firmware must be ordered separately to match specific configuration requirements.

Frequently Asked Questions

How does the SERCOS interface impact system integration?

SERCOS provides deterministic real-time communication, simplifying synchronization across multi-axis drives. It minimizes latency compared to older analog or fieldbus systems

Why is digital servo and resolver feedback flexibility important?

It allows compatibility with both modern encoders and legacy resolver-based motors. This supports retrofit projects without forcing motor replacement.

What temperature considerations must be observed during operation?

The unit performs reliably between +5 °C and +45 °C. Exceeding these ranges risks overheating or reduced efficiency of the cooling blower.

How does the line series “02” influence replacement parts availability?

Series identifiers ensure compatibility across components within the same design generation. This simplifies sourcing spares and reduces downtime in case of failure.

Does the design version “1” limit firmware upgrade options?

Not necessarily—firmware compatibility depends on hardware revisions and drive series. Always confirm the firmware release notes before attempting an update.
