The Rexroth Indramat drive controller MPN R911279153 (DKR04.1-W400N-BA01-01-FW) is engineered for precise industrial applications. This unit operates with a 3xAC 400–480 V ±10% power supply and AC 230 V ±10% control voltage, supporting system frequencies of 50–60 Hz and a control voltage frequency tolerance of ±2 Hz. It features an air cooling system with an integrated blower, and accommodates an external brake resistor for reliable deceleration independently of mains supply. The controller provides a peak current of 212–282 A and peak power output ranging from 92 to 125 kW. The design includes an analog command interface, supports digital servo and resolver feedback, and has a rated current of 400 A. It has a product mass of approximately 150 kg and utilizes a rigid DC bus without a brake chopper bleeder configuration.

Frequently Asked Questions

What implications does the 400 A rated current have for motor selection?

It supports large, high-torque motors commonly used in heavy machining and robotics. The wiring and protective devices must be sized accordingly to handle continuous current.

How does the design version ‘1’ impact spare parts compatibility?

A design version indicates a specific hardware revision. Maintenance teams must match spare parts and firmware versions to avoid incompatibility.

Why is function numeric code important when configuring the system?

It defines specific operating modes and parameter sets of the drive. Using the wrong code can result in improper operation or failure to integrate with the control system.

What are the real-world risks of not having a brake chopper in regenerative applications?

If the motor feeds energy back into the DC bus without dissipation, bus voltage can rise dangerously. This can cause overvoltage trips or damage unless external measures are installed.

In robotics applications, how does the DKR04.1-W400N-BA01-01-FW benefit precision control?

Its combination of high rated current and digital feedback ensures fast, accurate torque response. This allows precise motion control in multi-axis robotic systems.
