Product Description:

The DKR02.1-W200N-BE37-01-FW is a drive controller in the DKR Drive Controllers series. It is intended for high-power servo axes in metal-cutting, printing, and handling machines where precise velocity and torque regulation are required. By converting incoming three-phase power into a controlled DC link and modulating it for synchronous or asynchronous motors, the unit supports closed-loop motion control in complex automation cells. This allows the controller to regulate acceleration, steady-state speed, and load response with the consistent behavior expected in coordinated machine movements.

I/O to the machine control is handled through the SERCOS interface, so commands and parameter data travel over a fiber-optic ring. The drive accepts digital servo and resolver feedback, allowing operation with resolver-equipped motors as well as motors that use single-turn or multi-turn encoder systems. Internal temperature is managed by a built-in air blower that moves air through dedicated ducts and exhausts it at the top of the electronics rack. During deceleration, the unit uses no bleeder or brake chopper with a rigid DC bus, so regenerated energy must be routed to a common bus or handled by external braking equipment. The unit is manufactured by Bosch Rexroth Indramat. This supports use alongside related motors and drive components from the same platform.

The controller belongs to Line series 02, which places it in the second design line of this product range. It uses Design version 1 for this mechanical and electrical revision. The unit carries Function version 01 for its motion-control feature set. It is part of Product series DKR. These identifiers help distinguish the controller's revision and feature grouping without changing its role as a rack-mounted power and control module.
