Product Description:
The DKR03.1-W200B-BE37-01-FW is a digital drive controller developed for high-torque servo axes in automated machinery. It belongs to the DKR Drive Controllers series manufactured by Bosch Rexroth Indramat, and the “DKR” prefix in its code explicitly designates that product series. Inside an automation rack, the unit modulates DC link energy into a regulated three-phase output for synchronous or asynchronous motors, providing the velocity and position loops required for presses, gantries, and machining centers.
The controller exchanges cyclic motion telegrams over the SERCOS interface, a fiber-optic command bus that supports sub-millisecond synchronization between multiple axes. Regenerated kinetic energy is routed to an internal resistor because the drive is supplied with bleeder; this arrangement limits the DC bus voltage during deceleration events. Thermal management relies on air cooling with built-in blower, so cabinet airflow planning can be simplified to a single exhaust path. The blower’s constant flow maintains component temperatures under continuous load. For position verification it accepts digital servo and resolver feedback, enabling mixed encoder topologies on one axis without external converters.
Hardware identity is captured by design version 1, while application behavior is mapped through function numeric version 01; together they define firmware compatibility within the control family. The hardware belongs to line series 03, aligning its power section and connector layout with later platform releases. Within the larger architecture of the DKR product line, these identifiers allow field technicians to substitute boards and parameter sets without requalification. Standard commissioning tools recognize the selected drive controller and apply the correct diagnostic menus and tracing routines during service.
