DKR02.1-W200N-BT26-01-FW
DKR Drive Controllers
The Bosch Rexroth Indramat DKR02.1-W200N-BT26-01-FW from the DKR Drive Controllers series delivers robust drive control with a rated current (A) of 200 and advanced feedback options. It supports a high-speed SERCOS interface, ensuring deterministic communication and synchronization across multi-axis systems. The controller features a rigid DC bus design without a bleeder or brake chopper (No bleeder/ Without brake chopper, rigid DC bus), minimizing power losses and heat generation. Its compact chassis integrates a Cooling Method: Air (built-in blower) to maintain optimal operating temperatures in crowded control cabinets.
The DKR02.1-W200N is built to Design Version: 1 specifications and aligns with Line Series: 02 to ensure mechanical and electrical compatibility within existing installations. Equipped with Motor Feedback: Digital servo and resolver feedback, it delivers high-resolution position and velocity data for precise motion profiles. Firmware consistency is guaranteed by the Function Numeric Version: 01 platform, streamlining updates and reducing configuration errors. As part of the Product Series: DKR, this controller supports standardized mounting, cabling, and diagnostics tools across the Bosch Rexroth ecosystem.
Engineered for demanding automation tasks, the DKR controller excels in packaging, printing, and machine-tool applications that require rapid acceleration and fine torque control. Its robust modular design and integrated cooling blower reduce mean time to repair and simplify preventive maintenance. The result is a drive controller that combines high performance, reliability, and ease of integration in dynamic industrial environments.

Frequently Asked Questions
Why is the rigid DC bus design important?
A rigid DC bus minimizes energy loss and avoids extra heat, making cabinets easier to cool. It also improves efficiency in continuous-duty environments.
What cooling considerations are needed during cabinet design?
The integrated blower pushes air through the chassis, but spacing for airflow in dense cabinets is still essential. Overcrowding reduces cooling efficiency and shortens service life.
Can the DKR02.1-W200N-BT26-01-FW operate with both resolver and digital feedback?
Yes, it accepts both, allowing flexibility depending on motor type and resolution needs. This dual feedback support simplifies upgrades without replacing existing motors.
How does firmware consistency impact maintenance?
Having a fixed firmware platform reduces mismatches across drives in a system. This speeds up commissioning and prevents costly downtime from configuration errors.
How does modularity affect replacement time?
The controller’s modular layout allows individual parts to be swapped without disturbing the whole system. This reduces mean time to repair and simplifies preventive maintenance.
