The Bosch Rexroth MPN R911268695 (DKR02.1-W300N-BE11-01-FW) is a drive controller equipped with an isolating transformer, S1 reset key, and two control inputs accessible via the X9 connector. It supports communication through an RS-232 interface for PC or VT-100 terminal connectivity. The controller is compatible with both digital servo and resolver motor feedback, and features a SERCOS command interface. It operates with a nominal current of approximately 300A, a peak current rating of 212A, and supports a storage capacity of 55kW at 4kHz and 43kW at 8kHz. Air cooling is achieved with an integrated blower. The controller functions within ambient temperatures ranging from -30°C to 80°C (operational max 55°C), and can be installed up to an elevation of 1,000m. The unit weighs 104kg and includes a supplementary 1.7kg M1-RAC accessories kit. It is designed without a bleeder or brake chopper, and features a rigid DC bus.

Frequently Asked Questions

How does the DKR02.1-W300N-BE11-01-FW handle multi-axis synchronization?

Its SERCOS interface ensures deterministic timing, allowing multiple axes to remain in sync without additional wiring complexity.

What is the impact of not having a brake chopper in this controller?

Without a brake chopper, the DC bus maintains rigidity, but external energy dissipation may be required in high-inertia stop scenarios.

Can the DKR02.1-W300N-BE11-01-FW operate effectively in continuous duty cycles?

Yes, its integrated blower cooling supports sustained high current without thermal derating under long-duration operation.

How does resolver feedback support improve reliability?

Resolvers are robust against electrical noise and vibration, making them ideal for harsh industrial environments with EMI concerns.

What installation considerations arise from the 300 A current rating?

Proper cabling gauge and busbar design are essential to safely handle sustained currents and prevent overheating.
