The R911265631 (DKR03.1-W200Z-BE12-01-FW) is a Bosch Rexroth DKR series controller designed for precise motor control and regulation. It consists of a basic unit with auxiliary modules, command interface cards, and a software module. Command communication utilizes a SERCOS interface. The controller is equipped for digital servo and resolver feedback. It features air cooling with a built-in blower and supports a rated current of 200A. The brake resistor achieves a peak power of 40kW and continuous power of 1kW. Safe operation requires drives to remain still before accessing hazardous areas. The unit must be stored and transported between -30°C and 80°C. A minimum airflow of 300m³/h is required, along with at least 100mm distance between control and power or signal cables. Overloading and improper handling may result in thermal hazards or equipment damage.

Frequently Asked Questions

Why is a SERCOS interface important for machine control?

The SERCOS provides deterministic communication, ensuring precise synchronization between drives and controllers. This reduces jitter and increases reliability in multi-axis systems.

Can the DKR03.1-W200Z-BE12-01-FW be used with both old and modern feedback devices?

Yes, its dual resolver and digital servo feedback support makes it compatible with legacy motors as well as newer high-resolution servo systems. This flexibility eases retrofits and mixed-system integration.

How does the “line series 03” impact compatibility with other components?

Line series defines mechanical and electrical standardization across that generation. Using the same series ensures easier spare parts sourcing and consistent wiring layouts.

What are the implications of a design version 1 unit?

Version numbers typically reflect hardware or firmware iterations. A design version 1 indicates it’s the base release, which may require firmware updates for advanced features.

How does digital servo feedback improve motion precision?

Digital signals reduce noise interference compared to analog feedback. This leads to finer position control and smoother axis movement in high-speed machining.
