The R911295741 (DKR02.1-W200N-BA07-01-FW) is a Bosch Rexroth drive controller engineered for the regulation and supervision of electric motor operations in industrial environments such as machine tools and printing equipment. This unit supports modification prior to commissioning to adapt to specific application requirements. It includes an onboard blower for air cooling, operates with a rated current of 200 A, and utilizes digital servo as well as resolver feedback for precise motion control. The controller features an analog command interface, is configured without a brake chopper and a rigid DC bus, and requires a three-phase power supply of AC 400–480 V (±10%) with a control voltage of 230 V AC (±10%). Design version is 1, and the function numeric codes are 07 and 01. Recommended ambient operating temperature range is 5–45°C.

Frequently Asked Questions

What benefits does a rigid DC bus design bring to system wiring?

It simplifies connections by avoiding additional chopper circuits and reduces points of failure. This allows cleaner layouts in multi-axis configurations.

Can the DKR02.1-W200N-BA07-01-FW handle mixed motor feedback types in one setup?

Yes, it accepts both resolver and digital servo inputs, enabling use with diverse motor technologies. This flexibility helps during retrofits or mixed-drive systems.

Does analog command interface limit system precision compared to digital?

Not necessarily, since the feedback loop is fast enough for sub-millisecond response. Precision depends more on tuning and application-specific demands.

How does the DKR02.1-W200N-BA07-01-FW improve fault handling in automated lines?

It features built-in diagnostics that allow predictive maintenance and early fault detection. This minimizes downtime by isolating issues before failure.

What role do conformally coated electronics play in this controller’s performance?

They protect against moisture, dust, and chemical contaminants. This ensures reliability in harsh industrial environments like food processing or outdoor handling.
