Product Description:

The DKR02.1-W300Z-BE11-01-FW is a drive controller manufactured by Bosch Rexroth Indramat for the DKR Drive Controllers series. It operates as a servo amplifier that conditions line power and delivers regulated three-phase current to AC motors, allowing precise speed and position control in automated presses, machining centers, and material-handling axes where repeatable motion and steady torque are required throughout the duty cycle. For closed-loop operation, it accepts digital servo and resolver feedback, enabling the drive to process high-resolution position data while still supporting older resolver-equipped motors in mixed installations or retrofit systems.

This controller communicates with the host PLC over the SERCOS interface, giving deterministic cycle timing and parameter exchange across a fiber-optic ring so coordinated axes can respond to synchronized command updates without timing drift between devices. Its output stage is rated for a continuous current of 300 A, which lets the unit supply large synchronous or induction motors during sustained load and demanding acceleration periods. Thermal loads are removed by air cooling with a built-in blower; the integrated fan moves cabinet air across the heat sink to stabilize semiconductor temperatures during high-duty operation and repeated load changes. The product is design version 1, which identifies its component placement and connector pinouts.

The unit uses Function Numeric Version 01 and is part of Line 02 in the type designation. These codes identify the correct parameter group and the matching revision level for the controller, helping keep startup settings aligned with the installed hardware and reducing confusion when similar modules are used in the same cabinet. The internal logic, gate drivers, and protective functions follow the standard layout used across this product line, so operating behavior remains consistent with related modules that share the same control platform.
