The R911273637 (DKR02.1-W200Z-BE12-01-FW) is a Bosch Rexroth servo drive designed for integration with various industrial motors, optimizing rotor position management at low speeds via an internal position control loop and high-resolution feedback. It features closed-loop feedback for precise, real-time position and speed correction. The unit supports synchronization with a PC during commissioning through SERCOS interface and DriveTop/SERCTOP technologies, enabling advanced programming, diagnostics, and parameterization. The drive is engineered for three-phase supplies in the 400–480 V range and operates with 2AD, LAR, 1MB, and LAF motors, supporting power outputs from 10 to 93 kW and rated at 200 A. It uses digital servo and resolver feedback, air cooling with a built-in blower, and belongs to the DKR product series, version 02.1, with function numeric version 01.

Frequently Asked Questions

How does the SERCOS interface benefit the DKR02.1-W200Z-BE12-01-FW in multi-axis systems?

It ensures deterministic, low-latency communication between drives and controllers. This allows synchronized motion across multiple axes without requiring additional communication layers.

What is the practical role of the integrated blower cooling in continuous duty applications?

The blower maintains stable operating temperatures during sustained high current use. This prevents thermal derating that would otherwise reduce drive output capacity.

Can resolver feedback be combined with digital servo feedback in the same setup?

Yes, both feedback types can be integrated to support different motor technologies. This flexibility simplifies retrofitting systems with mixed encoder standards.

What advantage does the DKR02.1-W200Z-BE12-01-FW’s compact footprint provide during cabinet design?

The reduced size allows higher packing density in control cabinets. This saves valuable floor space while minimizing cable routing complexity.

How is the DC-link bleeder circuit relevant to machine safety?

It safely discharges stored energy when the system powers down. This prevents residual voltage from damaging components or endangering technicians.
