Product Description:

The Bosch Rexroth Indramat DKR 3.1-W200Z-BE28-00 is an AC drive controller in the DKR Drive Controllers series. It governs rotary axes in automated machine tools, packaging lines, and material-handling stations by converting high-level motion commands into regulated three-phase output for the connected motor. Installed between the plant power bus and the servo windings, it maintains commanded velocity and torque profiles while monitoring current flow and internal temperature during operation. This arrangement allows the controller to support repeatable axis motion while keeping the motor response aligned with the demands of the machine cycle.

The power stage exchanges telegrams with CNCs or PLCs through the SERCOS interface, providing deterministic fiber-optic communication for closed-loop control. Internal components are cooled by a built-in air blower, so heat can be removed without adding separate external cooling equipment to the cabinet. The inverter can supply a continuous current of 200 A, which suits applications that require sustained motor output over extended duty periods. The unit is Design Version 1, indicating the first electrical and mechanical release of this model and helping identify its product generation within the series.

A listed overload current value is 141 A, which is provided as part of the unit's operating data. The controller is a Digital Intelligent AC Drive Controller, so diagnostic, monitoring, and parameter storage functions are handled by embedded logic inside the unit. The drive uses Function Module Version 00 for its application configuration. Position data can be processed from both digital servo feedback and independent resolver feedback, allowing the controller to work with different compatible motor feedback systems on the same platform.
