Product Description:

The DKR02.1-W200N-BA03-01-FW is a drive controller produced by Bosch Rexroth Indramat and belongs to the DKR Drive Controllers series. It delivers regulated DC power and closed-loop control signals to Indramat servo axes used on gantries, machining centers, and transfer lines. By coordinating torque, speed, and position in real time, it forms the link between the motion program generated by the CNC or PLC and the mechanical axis that performs the work in an automated cell. Because the control loop is handled inside the drive, the machine control can send motion references while the unit manages the fast electrical response needed at the motor. This arrangement supports accurate axis movement during continuous industrial operation.

Command signals reach the unit through an analog interface, so the controller maps ±10 V velocity or torque references directly into drive output without fieldbus conversion. Thermal management is handled by a built-in air blower; the integral fan forces cabinet air across the power stage to keep semiconductor junction temperatures within limits during continuous duty. Motor position is monitored through digital servo and resolver feedback, allowing the controller to interpret either encoder format and maintain accurate current-loop control. Support for both feedback types helps the unit fit systems that use different motor feedback devices. The DC link has no bleeder, so excess regenerative energy is returned to the line or must be absorbed externally because no brake chopper is fitted in the drive.

This controller uses Design version 1. Within the naming key, Function code 03 marks the application-specific parameter group, while Function version 01 indicates the initial revision of that parameter set. The controller is part of Line series 02, which matches the housing and interface generation used for this model. These identifiers distinguish this unit from other controller variants that use different option combinations and internal layouts.
