Product Description:
The DKR 3.1-W200N-BE24-00 is an AC drive controller manufactured by Bosch Rexroth Indramat for the DKR Drive Controllers series. It regulates power supplied to synchronous and induction motors in automated machinery, coordinating torque, speed, and position loops within multi-axis motion platforms. By converting mains energy into DC-link power and modulated output phases, the unit acts as the central interface between the plant’s electrical supply and the motion components commanded by a PLC or CNC. This arrangement allows the controller to manage motor current in response to real-time commands while reporting operating data to the higher-level control system.
The drive exchanges motion commands and status data through a SERCOS interface, allowing deterministic fiber-optic communication with higher-level controllers. Thermal management is handled by a built-in air blower, so the cabinet layout must provide sufficient airflow around the unit to maintain reliable cooling. The controller has a nominal current rating of 200 A, representing the continuous RMS phase current that the power stage can sustain without derating under the stated operating conditions. The unit has Design Version 1, which supports the corresponding electrical and mechanical configuration of the controller. Its installed control card is designated Function Module Version 00, indicating the baseline module configuration for this model.
Motor feedback processing accepts digital servo and resolver feedback, enabling operation with high-resolution digital feedback devices and analog resolver transducers. During acceleration or sudden load changes, the inverter can deliver a peak armature current of 141 A for short-term dynamic demands. The controller uses a rigid DC bus without a bleeder, so regenerative energy must be returned to the mains or absorbed by suitable external components. The unit is classified as a Digital Intelligent AC Drive Controller, combining power electronics with embedded signal processing for closed-loop motion control. Its feedback capabilities allow the control system to monitor rotor position and velocity, correct motion errors, and maintain stable operation as the connected mechanical load changes.
