The R911277676 (DKR02.1-W300N-BE11-02-FW) is a Bosch Rexroth Indramat drive controller engineered for precise control and monitoring of electrical motors in industrial applications. It supports digital servo and resolver feedback through the X4 port and utilizes the SERCOS interface for communication. The unit handles an AC supply voltage of 3 x 400-480V, provides a nominal current of approximately 300A, and achieves continuous output power of 55/43 kW at a constant current of 141/110A. Heat dissipation is managed via an integrated blower, rated at 1200W. The controller features a rigid DC bus without a bleed resistor or brake chopper, implements IP20 housing protection, and operates at ambient temperatures up to +45°C without derating.

Frequently Asked Questions

How does using a SERCOS interface affect system integration?

SERCOS provides deterministic, real-time communication with controllers. This ensures reliable synchronization across multiple drives and sensors.

What impact does the rigid DC bus design have on installation?

It removes the need for extra brake resistors, simplifying cabinet wiring. This directly cuts down on installation time and cost.

How does this controller maintain accuracy under dynamic loads?

Advanced digital servo control adjusts torque and speed in real time. This allows the drive to maintain precision during sudden changes in load.

Why is nominal current alignment important in this drive?

The 300A nominal current matches the continuous rating, so the system can run near capacity without derating. This improves reliability in constant high-load operations.

What applications benefit most from this controller’s design?

It excels in machine tools, spindles, and packaging machinery where rapid acceleration and high torque are needed. Its simplified cabinet requirements make it ideal for tightly packed automation cells.
