DKR02.1-W200N-BE24-01-FW
DKR Drive Controllers
DKR02.1-W200N-BE24-01-FW, Bosch Rexroth Indramat, DKR Drive Controllers deliver a 200 A rated current for precise motion control in industrial servo systems. The controller features a built-in blower cooling mechanism to maintain optimal thermal stability under load. Integration is simplified via the SERCOS interface for high-speed deterministic communications. A No bleeder/Without brake chopper, rigid DC bus architecture ensures clean DC link operation without external braking resistors.
The design incorporates a solid Design Version 1 chassis within the Line Series 02, tailored for rugged factory environments. It accepts Digital servo and resolver feedback on the motor feedback channels, enabling sub-microsecond loop response and high positioning accuracy. As part of the Product Series DKR, the unit is identified by its Function Numeric Version 01, guaranteeing compatibility with legacy DKR modules. The air-cooled topology relies on an Air (built-in blower) scheme that removes fans and reduces maintenance while preserving IP20-level protection.
Engineers appreciate the controller’s compact footprint and seamless integration into OEM machine designs, from printing presses to CNC lathes. Its robust thermal management and absence of external brake choppers enhance reliability in continuous-duty applications. With a global one-year warranty and altitude rating below 1000 meters, the DKR02.1-W200N-BE24-01-FW is an ideal choice for production lines demanding precision, uptime, and straightforward serviceability.

Frequently Asked Questions
How does the DKR02.1-W200N-BE24-01-FW handle excess heat during continuous duty?
It uses an integrated blower system that circulates air across internal components. This avoids reliance on external fans and minimizes thermal drift during extended operation.
What advantage does a rigid DC bus architecture provide in this controller?
It ensures stable DC link operation without requiring external braking resistors. This simplifies installation and reduces electrical noise in multi-axis systems.
Why is SERCOS communication relevant for this drive?
SERCOS provides deterministic, high-speed synchronization between drive and control hardware. This enables sub-millisecond command execution critical in precision machining.
How does digital servo feedback improve accuracy?
Digital feedback allows higher resolution and faster signal processing compared to analog encoders. This results in finer motion control and reduced position error.
What considerations exist for altitude installation limits?
Operation is rated below 1000 meters to maintain cooling efficiency. Higher elevations may require derating or additional thermal management strategies.
