The R911310710 (DKR02.1-W300N-BA05-01-FW) is a Rexroth Indramat DKR series drive controller engineered for precise motor control in industrial automation. This unit connects to a grounded three-phase AC supply and directs regenerated braking energy back to the mains, incorporating optional integrated brake resistors for deceleration during mains failure. Modules for adaptation to varied applications include a basic unit, plug-in modules, software module, and command interface cards, with labeling for identification. It utilizes air cooling via a built-in blower, operates on a 230V AC control voltage at 50/60Hz, and supports a peak current of 212A with a nominal current rating of approximately 300A. The controller features analog interface command communication, digital servo, and resolver feedback. The configuration is without a brake chopper, using a rigid DC bus.

Frequently Asked Questions

Does the DKR02.1-W300N-BA05-01-FW support integration with modern fieldbus systems?

While primarily designed with analog interfaces, it can be paired with converters to link to fieldbus networks. This ensures compatibility with advanced automation infrastructures.

How does the rigid DC bus in the DKR02.1-W300N-BA05-01-FW improve reliability?

The rigid design minimizes fluctuations and improves stability across connected modules. It also reduces the likelihood of voltage drops during load peaks.

Do the cooling fans in the DKR02.1-W300N-BA05-01-FW require periodic replacement?

Yes, the built-in blower may need servicing or replacement after prolonged continuous use. This ensures optimal airflow and prevents overheating during heavy-duty operation.

Why does the Bosch Rexroth Indramat DKR02.1-W300N-BA05-01-FW rely on digital servo/resolver feedback?

It enables higher accuracy by synchronizing motor position and speed data. This is especially important in robotic and CNC machining applications.

Does the DKR02.1-W300N-BA05-01-FW allow retrofit into existing servo drive cabinets?

Yes, its modular layout simplifies replacement in existing enclosures. This reduces installation downtime and minimizes the need for cabinet modifications.
