Product Description:
The DKR03.1-W200Z-BE37-00 is a drive controller built by Bosch Rexroth Indramat within the DKR Drive Controllers series. It is used in multi-axis industrial machinery to regulate current, speed, and position loops for coordinated servo motor control. The unit reads digital servo and resolver feedback from the connected motor so closed-loop performance can be maintained during rapid load changes. This makes it suitable for synchronized motion tasks in equipment such as transfer systems, machine tools, and packaging lines. The product is part of line 03, has design version 1, and has function module version 00.
Communication with higher-level control systems is handled over the SERCOS interface, allowing deterministic command exchange while the power stage switches at 4 kHz. At that switching frequency, the drive can deliver a continuous phase current of 92 A, which corresponds to about 35 kW of mechanical power with a matched servo motor. Internal logic and I/O are powered by an AC 230 V ±10% control supply, and a built-in air blower moves cooling air through the heat sink to help stabilize semiconductor temperature. The power section is built for current rating 200, placing the unit in the higher-output range of this controller platform. This arrangement supports reliable thermal control when the drive is installed in an enclosed electrical cabinet.
During acceleration or short overloads, the power stage can supply a peak current of 141 A without exceeding its intended thermal range. Mains terminals accept a three-phase input of 3×AC 400–480 V ±10%, which suits standard industrial power systems in the 400 V class. Under full load, the module dissipates 1200 W of heat, so cabinet airflow must be planned accordingly to prevent heat buildup around the controller. The assembly has a mass of 49 kg, which should be considered when planning mounting support and equipment handling. Its combination of high current capacity and substantial heat dissipation makes correct enclosure layout important for stable operation.
