Product Description:

The DKR 3.1-W200N-BE04-00 drive controller is produced by Bosch Rexroth Indramat within the DKR Drive Controllers series. Engineered for multi-axis motion platforms, the unit regulates power converters and synchronizes servo motors in automated machinery. It integrates seamlessly with Rexroth power sections and supervises deceleration energy, motion profiles, and fault handling routines for presses, gantries, and machining centers.

In operation the controller exchanges real-time setpoints through the SERCOS interface, enabling deterministic coordination with CNC or PLC hosts. Thermal management relies on Air (built-in blower) cooling that directs internal flow across heat-producing power modules. The DC link is configured with without brake chopper hardware, so excess regenerative energy must be handled by upstream infrastructure; this arrangement also establishes a rigid DC bus that keeps link voltage stable during heavy acceleration. By omitting energy-dissipating elements, the electrical design keeps cabinet heat load low and simplifies wiring schemes. Closed-loop positioning is supported because the power section can process digital servo and resolver feedback arriving from connected motors, allowing accurate velocity and position control across a wide torque range.

This unit comes from the DKR Drive Controllers series manufactured by Bosch Rexroth Indramat. The hardware identification shows design revision 1, which pinpoints the mechanical layout and connector placement used throughout the cabinet system. Control firmware is classified as function numeric version 00; matching this code with servo-drive parameter files ensures compatibility when the controller is exchanged or installed as a spare. Together, these identifiers simplify lifecycle management by giving technicians a consistent reference when ordering, commissioning, or updating drives across multiple machines.
