The Bosch Rexroth MPN R911293329 (DKR02.1-W200B-BE56-01-FW) is a drive controller designed for installation in control cabinets or protective housings that comply with DIN VDE 0160 standards, ensuring electrical safety and isolation from direct machinery contact. It operates with a maximum ambient temperature of 55°C under adapted data, employing a load-dependent energy dissipation configuration with a built-in blower. The controller uses a SERCOS interface for communication and requires a minimum separation of 100 mm between power and control cables. It is specified with a control voltage of 230VAC ±10%, a control power of 200VA, and a continuous regenerated power capacity of approximately 43 kW. The unit includes a bleeder, supports both digital servo and resolver motor feedback, and features five plug-in module slots, with the fifth slot designated for software modules. It weighs approximately 104 kg and utilizes fiber optic cables for connection to higher-level control units.

Frequently Asked Questions

Why is the inclusion of a bleeder circuit important in this drive controller?

The bleeder dissipates excess regenerative energy during motor deceleration. This prevents overvoltage faults and protects connected components.

Does the SERCOS interface in the DKR02.1-W200B-BE56-01-FW limit integration options?

No, it enables high-speed deterministic communication with most modern motion controllers. However, legacy systems without SERCOS support require a gateway or interface upgrade.

What is the role of resolver feedback compared to digital servo feedback?

Resolver feedback offers robustness in harsh conditions like high vibration or temperature. Digital servo feedback enables precise positioning in demanding motion profiles.

How does the housing design impact protection against environmental factors?

The housing is typically rated around IP20, meaning it is protected against solid objects but not moisture. This limits installation to clean, dry, and controlled environments.

How does the drive’s design version number affect compatibility?

The version number ensures firmware and hardware match with supported components. Using the wrong version can lead to configuration errors or unsupported features.
