Product Description:

The DKR03.1-W200Z-BE37-01-FW is a drive controller manufactured by Bosch Rexroth Indramat for the DKR Drive Controllers series. It serves as the power and control interface between an industrial motion controller and a connected servo motor, regulating torque, speed, and position for coordinated motion in automated equipment. This role allows the controller to support axis functions such as acceleration control, steady running speed, and repeatable positioning in material handling, packaging, and other industrial machinery. The part code identifies the unit's configuration within the series and separates this model from other versions that use different cooling arrangements or line assignments.

The unit communicates with the automation host over the SERCOS interface, a real-time fiber-optic network that transfers setpoints, diagnostic data, and parameter blocks with very low latency for synchronized machine motion. Thermal management is performed by a built-in air blower, so the integrated fan moves ambient air through the heat sink without requiring an external liquid circuit. The unit is Design Version 1 and Function Numeric Version 01, which identify its assigned design and function grouping within the product series.

The unit is in line series 03, which uses standardized enclosure dimensions and connector locations for consistent installation in compatible drive systems. Feedback processing accepts digital servo and resolver feedback, allowing the drive to close position loops with either high-resolution encoders or legacy resolvers without external converters. Within the DKR Drive Controllers series, the embedded motor feedback evaluator also supports stall detection and thermal model functions that can shut down the inverter when operating limits are approached to help protect the connected motor and power stage during abnormal load conditions.
