Product Description:

The DKR03.1-W200N-BE11-01-FW is a drive controller produced by Bosch Rexroth Indramat. It belongs to the DKR Drive Controllers series and is used to regulate torque, speed, and position of AC servomotors in automated machine axes. The unit forms the power conversion and control stage between the automation system and the motor. It converts three-phase mains power into a controlled DC link and then into synchronized output pulses for precise motion in metal-cutting, printing, and material-handling equipment. In a typical installation, it receives motion commands from a higher-level control and converts them into motor current that matches the requested acceleration and holding behavior. This arrangement lets the axis respond accurately during startup, contouring, and braking events.

Cooling air is moved through the heat-sink channels by a built-in air blower, so the controller removes thermal load without external ducting. Command data enter through the SERCOS interface, allowing cyclic setpoints, status words, and diagnostic data to travel over a real-time fiber-optic ring. Rotor position is processed through digital servo and resolver feedback, which supports closed-loop current and speed control with one hardware option. This combination allows the drive to monitor rotor movement and maintain stable control across changing load conditions. The power section uses a rigid DC bus without a bleeder or brake chopper, so regenerated energy must be handled by the upstream supply. The unit is part of Line 03, which places it in the third design line of this controller platform.

The unit is design revision 1 and carries function numeric version 01, which keeps its parameter structure aligned with that revision. The designation DKR identifies the controller family used for this model. These coded identifiers distinguish the control variant and operating behavior assigned to the unit. Wiring practice, ambient conditions, and EMC limits must follow the published operating requirements so the controller can maintain stable motion control in multi-axis systems.
