The R911293871 (DKR03.1-W200N-BT19-01-FW) is a Bosch Rexroth drive controller engineered for precise regulation of electric motors, including compatibility with spindle motors (such as 1MN, ADF, and 2AD) and linear motors (LSF, LAF). It features a 200 A rated current, operates on a 3-phase AC power supply (400 ... 480 V, ±10%) and a 230 V AC control voltage (±10%), and is designed for installation at elevations up to 1000 m with an operating temperature range of +5°C to +45°C. The controller uses a built-in air blower for cooling and supports digital servo and resolver feedback through a SERCOS interface, with configuration options including a rigid DC bus and no bleeder or brake chopper. It is suitable for integration in systems requiring accurate motor control and a wide speed range.

Frequently Asked Questions

How does the DKR03.1-W200N-BT19-01-FW handle excess energy without a brake chopper?

It uses a rigid DC bus design that directs regenerative energy back into the system instead of dissipating it as heat. This reduces component count and simplifies installation.

What is the advantage of the built-in blower cooling system?

The blower maintains consistent airflow over internal electronics, reducing thermal stress. This extends component life and avoids the need for external cooling infrastructure.

Can the DKR03.1-W200N-BT19-01-FW integrate with legacy motor types?

Yes, it supports resolver and digital servo feedback, allowing compatibility with older motors. This enables upgrades without replacing existing motor hardware.

How does the rigid DC bus contribute to reliability?

By eliminating the need for external bleeder circuits, fewer components are exposed to failure. This design also reduces energy loss and wiring complexity.

How does digital servo feedback enhance precision?

It provides high-resolution position sensing, enabling tight control of speed and torque loops. This results in smoother motion and reduced positioning error.
