Product Description:

Bosch Rexroth Indramat supplies the DKR02.1-W200N-BA09-01-FW as part of the DKR Drive Controllers series. As a Digital Intelligent AC Drive Controller, this unit coordinates high-power servo axes in automated machine tools and production lines. The design integrates line-side rectification, inverter stages, and drive intelligence in a single housing, so it converts three-phase mains energy into regulated motor current for precise velocity and torque control. It is intended for applications that require coordinated motion and stable current control under varying load conditions.

At a switching frequency of 4 kHz, the drive sustains a continuous output of 120 A, delivering approximately 47 kW to the attached motor. Control electronics are supplied from a separate AC 230 V ± 10% source, while the power section is rated for 3x AC 400 to 480 V ± 10%. Internal thermal management relies on a built-in air blower that forces cooling air across the heat sink. Because the DC bus is rigid and the unit has no bleeder or brake chopper, excess regenerative energy must be handled externally. This arrangement is suited to installations where braking energy is managed by the surrounding drive system rather than inside the controller.

During transient events, the inverter can rise to a peak of 141 A, providing short-term current headroom without pushing the continuous rating into overload. These operating conditions contribute to a total heat dissipation of 1600 W, so panel ventilation must be able to remove that thermal load. The controller has a mass of 104 kg, which affects cabinet support and handling during installation. Command signals enter through an analog interface, and motor feedback can be digital servo feedback or resolver feedback, allowing flexible loop configuration. The unit is design version 1, belongs to line series 02, and uses function module version 01 to match related DKR accessories.
