The Rexroth Indramat MPN R911276572 (DKR02.1-W200N-BE11-01-FW) is a DKR series drive controller engineered for accurate regulation of Indramat motors in applications such as NC machine tools and printing equipment. It operates on a three-phase AC input of 400-480 V at 50–60 Hz, with a rated output current of 200 A. The device includes an integrated blower for air cooling and utilizes digital servo and resolver feedback for motor feedback. Its modular architecture consists of dedicated slots for a command communication interface (SERCOS), a software module, and up to three additional optional modules. The unit is supplied without a brake chopper and supports a rigid DC bus configuration.

Frequently Asked Questions

What is the impact of the 200 A continuous current rating on machine selection?

It allows the drive to power larger servo motors or multiple axes with consistent torque output. This makes it suitable for heavy-duty applications like metal cutting or large-scale packaging.

Does the absence of a brake chopper in the DKR02.1-W200N-BE11-01-FW affect energy management?

Yes, braking energy cannot be dissipated internally and must be managed by external resistors or system design. This requires integrators to plan for energy feedback in regenerative applications.

How does SERCOS interface benefit real-time motion control?

It enables deterministic communication with low latency across multiple drives. This synchronization ensures precise coordination in multi-axis machinery.

Is the DKR02.1-W200N-BE11-01-FW suitable for robotics applications?

Yes, its fast feedback handling and stable current supply support high-speed axis movements. Robots benefit from reduced positioning error during repetitive tasks.

How does the drive’s cooling method affect enclosure requirements?

Since it uses forced-air cooling, enclosures must allow adequate ventilation paths. Poor airflow may reduce performance and shorten component life.
