Product Description:

The DKR03.1-W200Z-BE23-01-FW is a drive controller produced by Bosch Rexroth Indramat as part of the DKR Drive Controllers series. Installed inside multi-axis cabinets, it forms the power and control bridge between an industrial PC or PLC and the servo motors used in printing, converting, and handling equipment. By modulating its output stages in step with command data and motor feedback, the unit supports precise positioning, stable velocity regulation, and controlled torque limiting during continuous or rapid-cycle motion. This layout allows a machine axis to respond quickly to changing commands without relying on mechanical relays.

Its command layer relies on the SERCOS interface, a fiber-optic ring that carries synchronized setpoints with jitter below one microsecond for coordinated motion across several axes. Thermal management is provided by a built-in air blower, so an internal fan moves cabinet air across the heat sink and no external ducting is required. For position verification, the controller accepts digital servo and resolver feedback, allowing it to operate with motors fitted with either high-resolution encoders or rugged resolver transducers. The control loop can therefore work with different motor feedback types while maintaining synchronized axis behavior during repetitive production cycles.

The unit is design version 1 and part of line 03. Its function numeric version is 01, which ties the parameter set and diagnostic messages to a specific release level. The product flag DKR identifies the controller within the series, and these codes are used with the model number to keep the selected operating functions consistent with the installed hardware. Because the identifiers are fixed for this unit, the control structure remains matched to its intended drive configuration.
