The Rexroth Indramat R911280236 (DKR02.1-F300N-BE84-01-FW) is a liquid-cooled drive controller for electrical motor applications, supporting direct connection to a 3-phase AC 400–480V power source (±10%) at 50/60 Hz. It achieves a rated current of 300 A, with continuous output power at 43 kW, and regeneration up to 93 kW. The device operates with switching frequencies of 4/8 kHz, accommodating continuous currents of 141/110 A, and power losses of 1800W dissipated via cooling. It integrates an ESM02.3 firmware module, supports SERCOS interface, and enables digital servo and resolver feedback. The unit has no brake chopper, offers IP20 protection, functions within temperatures up to +45°C, and weighs approximately 104 kg.

Frequently Asked Questions

In which situations is liquid-cooled drive technology preferred over air-cooled types?

Liquid cooling is chosen where space is limited or ambient air circulation is insufficient, such as enclosed machine tool cabinets.

Can the DKR02.1-F300N-BE84-01-FW be applied in multi-axis systems?

Yes, its SERCOS interface enables synchronization with multiple axes, making it suitable for complex CNC or robotic systems.

How does line series 02 influence support and upgrade options?

Drives in a common line series share architecture, simplifying service, firmware updates, and replacement within that family.

What installation consideration arises from the 300 A current capacity?

The drive requires appropriately rated power cabling and protective devices to safely handle high current during continuous duty.

Why is a no-bleeder configuration significant in the DKR02.1-F300N-BE84-01-FW?

Without a brake chopper, excess regenerative energy must be managed externally, often requiring system-level energy handling solutions.
