Product Description:

Bosch Rexroth Indramat's DKR03.1-W200N-BE14-02-FW belongs to the DKR Drive Controllers series and is identified as a digital intelligent AC drive controller for multi-axis industrial machinery. By converting fixed-frequency mains power into regulated output for synchronous and asynchronous motors, the unit coordinates velocity, torque, and positioning tasks that are common in automated transfer lines, handling robots, and precision machining centers. This arrangement allows one controller to support demanding motion functions in systems that require accurate speed regulation and repeatable axis movement.

The drive exchanges setpoints and status data through a SERCOS interface, allowing deterministic fiber-optic communication with higher-level motion controllers. At a 4 kHz PWM frequency, it can deliver a continuous output of 92 A, enabling about 35 kW of shaft power without derating. Internal logic and I/O circuits are supplied from a separate AC 230 V control line, so the power stage can be isolated while diagnostics remain active. Thermal energy created by the switching devices is removed by a built-in air blower cooling system that directs airflow through the heat sink fins. For acceleration peaks, the inverter provides up to 141 A, giving additional margin for startup or rapid load changes.

The rigid DC-bus design operates without a brake chopper, so excess regenerative energy must be absorbed externally, an arrangement that suits applications using a common supply or mechanical flywheel. Resolver and digital servo feedback channels are processed simultaneously, allowing compatibility with motor families that require dual transducer support. When connected to a mains window of 3xAC 400 to 480 V, the controller's power section releases up to 1200 W of heat that must be removed by the cabinet ventilation system. Despite the high output range, the housing weighs only 49 kg, allowing panel installation with standard lifting equipment.
