Internal Product Review
The DKR02.1-W200 is a digital intelligent AC drive controller that feels well suited to demanding industrial motion systems. Air cooling with a built-in blower supports steady thermal control, and the AC 230 V control voltage helps with straightforward integration. Continuous output of about 47 kW with 120 A at 4 kHz makes this unit a strong choice for sustained drive performance.

Product Description:
The DKR02.1-W200 is a digital intelligent AC drive controller manufactured by Bosch Rexroth Indramat and assigned to the DKR Drive Controllers series. Designed for high-power servo and spindle axes, the unit supplies regulated three-phase output to large motors while coordinating feedback through the machine automation network. Within industrial automation, it converts line power into controlled current so that positioning, speed, and torque remain consistent under dynamic loading. It is intended for cabinet-based motion systems that require stable regulation on demanding axes.
This controller connects to plant mains with a rated power voltage of 3x AC 400 to 480 V, and that range lets the device tolerate ±10% fluctuations without derating. Its internal logic, contactors, and blower draw from a separate control supply of AC 230 V, which helps keep auxiliary functions available during mains disturbances. At a 4 kHz switching frequency, the power stage can deliver a continuous armature current of 120 A, and the circuitry is rated for a peak value of 141 A during acceleration or shock loading. At the same 4 kHz operating point, the controller provides a continuous drive power of 47 kW, allowing it to run large-format machining or printing heads without thermal cutback. A built-in air blower forces cooling air through the heat sink so that electronic losses are removed while cabinet space is conserved.
Thermal management is quantified by a total heat dissipation of 1600 W, a figure that guides enclosure ventilation and explains the presence of the integrated fan. The drive hardware, including inductors and bus capacitors, is engineered for a nominal current rating of 200 A, providing design headroom above the continuous value stated earlier. Mechanical integration is influenced by the weight of 104 kg, so slide-in frames or similar support methods are typically used during installation. The unit is part of line 02 and is identified as design version 1.
