The R911280726 (DKR02.1-W300N-BE56-01-FW) is a drive controller designed for precision control of Rexroth Indramat motors including LSF/LAF linear motors, 1MB frameless spindle motors, and 2AD/ADF AC main spindle motors. It operates with a three-phase AC input of 400–480 V (±10%) and requires a single-phase AC input of 230 V for control power with a 200 VA demand. The unit supports a rated current of 300 A with a peak capability of 212 A. SERCOS interface provides the command interface, while both digital servo and resolver feedback are supported for motor feedback. Cooling is achieved via a built-in air blower; no bleeder or brake chopper is present—indicating a rigid DC bus configuration. The module is built for modularity with a functional numeric code of 56, version 01, and measures 1000 x 440 x 290 mm, weighing 104 kg. Firmware is not included and must be sourced separately.

Frequently Asked Questions

What applications benefit from the DKR02.1-W300N-BE56-01-FW’s 300A current rating?

High-current capacity makes it suitable for heavy-duty automation, robotics, and material handling where large servo motors are used.

How does the absence of a brake chopper affect installation?

Without a brake chopper, the DC bus design is simpler but requires external braking solutions if regenerative loads are expected.

What is the advantage of using SERCOS as the command interface?

SERCOS ensures deterministic communication, enabling precise synchronization across multiple drives in complex motion systems.

Why is a built-in blower cooling method beneficial?

It simplifies thermal management by avoiding external cooling infrastructure, but placement must ensure unobstructed airflow.

How does digital servo and resolver feedback improve performance?

It provides high-resolution position and speed data, enabling accurate control even under variable load conditions.
