DKR04.1-W400E-BE56-01-FW

The Bosch Rexroth Indramat DKR04.1-W400E-BE56-01-FW drive controller is a high-performance module in the DKR Drive Controllers series. Designed for advanced motion control, it features an external bleeder with brake chopper and a rigid DC bus to maintain stable voltage under dynamic loads. With a SERCOS interface for precise command communication and an air cooling method (built-in blower), this unit ensures efficient thermal management for continuous operation.

Built on a robust Design Version 1 platform, the DKR04.1-W400E-BE56-01-FW delivers a rated current of 400 A to support demanding industrial servomotors. It accepts digital servo and resolver feedback signals to guarantee accurate speed and position control, while its Line Series 04 hardware architecture allows seamless integration into existing automation networks. The combination of a reliable rigid DC bus and advanced SERCOS command interface sets this controller apart, enabling rapid emergency stops and tight synchronization across multiple axes.

Built for versatility, the controller’s external bleeder and brake chopper combination provides enhanced safety during deceleration, reducing wear on mechanical components. Its built-in blower cooling supports operation in harsh environments by preventing thermal overload. As part of the DKR product series, it is fully compatible with Bosch Rexroth Indramat motion platforms, ensuring plug-and-play setup. This drive controller’s durability and efficiency translate into reduced downtime, precise motion control, and optimized energy usage, making it ideal for high-speed and high-torque industrial applications.
