Product Description:
The DKR02.1-W200B-BE32-01-FW is a Digital Intelligent AC Drive Controller built by Bosch Rexroth Indramat within the DKR Drive Controllers series. The product is part of Line 02, uses design version 1, and incorporates function module version 01. This controller supplies regulated three-phase power to large servo motors and manages positioning tasks through integrated processing and feedback channels, making it a central component in automated machine tools, presses, and handling systems. It is intended for industrial axes that require stable current regulation and consistent motion response during continuous operation.
The unit communicates with higher-level PLCs through a SERCOS interface, allowing deterministic command exchange and real-time status updates. At a 4 kHz switching frequency, the controller delivers a continuous output current of 120 A and continuous power of 47 kW. For short acceleration bursts, the controller can deliver a peak current of 141 A, giving additional torque headroom before thermal limits intervene. Internal losses, fan power, and bleeder dissipation combine to a total heat output of 1600 W, so cabinet ventilation must remove this heat to keep electronic components within the operating temperature range. The controller accepts digital servo and resolver feedback channels, and power is supplied from a three-phase mains connection rated at 400 to 480 V AC ±10%.
An internal brake resistor continuously absorbs up to 1.5 kW of regenerative energy released during deceleration, and it can store a maximum of 240 kWs before thermal protection activates. Control electronics draw auxiliary power from a separate AC 230 V ±10% source, which allows communication activity and stored settings to remain available when the main contactor is open. Forced-air cooling is provided by a built-in blower to support heat removal during sustained operation. The overall assembly weighs 104 kg, which affects panel layout and handling during installation. This separate control supply also supports orderly system behavior during shutdown states or brief interruptions of the main power path.
