Product Description:
The DKR02.1-W200N-BT59-01-FW is an AC drive controller manufactured by Bosch Rexroth Indramat within the DKR Drive Controllers series. It functions as a closed-loop power stage that delivers controlled three-phase power to servomotors, enabling rapid positioning and stable speed regulation in automated machinery. As part of the Digital Intelligent AC Drive Controller group, it is intended for demanding axes where coordinated motion and high continuous current are required.
The unit exchanges setpoint and diagnostic data through a SERCOS interface, allowing deterministic communication with motion PLCs. During continuous operation at a switching frequency of 4 kHz, it can supply 120 A of output current, which corresponds to a continuous mechanical power capability of 47 kW under rated conditions. The control circuits use a supply of AC 230 V ± 10%, so the installation must provide a stable single-phase source. Thermal management is handled by a built-in air blower that moves cooling air through heat-sink channels, maintaining safe semiconductor temperatures without external liquid cooling. A rigid DC bus is used because no bleeder or brake chopper is installed, so regenerated energy must be handled by the connected drive system.
The drive can deliver up to 141 A for short intervals to cover acceleration peaks, and it accepts a mains supply of 3×AC 400–480 V ± 10%, matching common plant power networks. Overall heat loss reaches 1600 W, which is important for enclosure ventilation planning. With a transport weight of 104 kg, the mounting structure must support substantial mass during installation and operation. The unit has current rating code 200, design version 1, function module version 01, and line series 02. Digital servo and resolver feedback channels are supported for precise motor position verification during closed-loop control.
