Product Description:

The DKR03.1-W200N-BA01-01-FW is a Bosch Rexroth Indramat drive controller from the DKR Drive Controllers series. It is designed for cabinet-based automation systems where motor speed, torque, and axis behavior must be regulated through a dedicated drive controller. In operation, the unit processes command signals and motor feedback to adjust the output stage in real time, helping maintain stable motion during demanding machine cycles such as machining, forming, and material handling.

This configuration uses an analog command interface, allowing it to receive control signals from compatible CNC or PLC hardware. Cooling is handled by a built-in blower, which moves air across the heatsink to manage operating heat without requiring a liquid-cooling circuit. Motor feedback is supported through digital servo and resolver feedback, helping the controller maintain accurate commutation and drive response. The unit is configured with no bleeder or brake chopper and a rigid DC bus, so regenerated energy must be handled by the larger drive system. Its 03 line designation identifies the controller’s construction stage within the DKR family.

The type code also defines the unit’s version and control configuration. Design version 1 identifies the mechanical release of the controller, while function code 01 and function numeric version 01 specify the installed functional configuration for the application. The DKR platform supports consistent mounting and connection practices across compatible controllers, making it suitable for multi-axis systems where standardized cabinet layout and drive replacement planning are important.
