DKR03.1-W100N-BE79-01-FW

The DKR03.1-W100N-BE79-01-FW drive controller by Bosch Rexroth Indramat is part of the renowned DKR Drive Controllers series, engineered to deliver precise motor control for industrial automation applications. Rated for three-phase AC 3 × 400–480 V input and a control voltage of AC 230 V ±10% at 50–60 Hz, this unit supports a Rated Current (A) of 100 A and employs an Air (built-in blower) cooling method to ensure stable operation in demanding environments. Its primary function is to govern the speed, torque, and position of electrical motors in printing machines, NC machine tools, and similar equipment, providing reliable power delivery and motion control.

In terms of technical specifications, the DKR03.1-W100N-BE79-01-FW operates at switch frequencies of 4 kHz and 8 kHz, delivering continuous currents of 71 A and 60 A, respectively, with continuous power ratings of 26 kW and 22 kW. It also handles a peak current of 71 A for instantaneous power spikes, enabling it to manage rapid load changes without performance degradation. The controller’s command communication is handled via the SERCOS interface, ensuring deterministic real-time data exchange. Motor feedback is provided through Digital servo and resolver feedback, which enhances positioning accuracy and dynamic response. The drive dispenses heat at rates of 900 W through its power section and 600 W via the air channel, maintaining optimal thermal performance.

Additional features include a robust protection class of IP20 and a compact build weight of approximately 49 kg, excluding accessories. The drive is designed without a bleeder resistor (No bleeder/Without brake chopper), simplifying maintenance and reducing component count. Its modular base unit, DKR03.1-W100-B, supports five plug-in card slots—four for interface options and one for the software module containing the operating software and drive parameters. Function Numeric Version 01 and Design Version 1 ensure compatibility across the DKR product family. By combining high current capacity, advanced feedback options, and a built-in blower, this controller delivers exceptional efficiency, reliability, and ease of integration for demanding industrial environments.
