The R911276834 (DKR02.1-W300B-BE23-01-FW) is a Rexroth Indramat DKR02 series drive controller engineered for control of AC mains, frameless, and linear motors commonly applied in printing and NC-controlled machine tasks. Operating with a power input of 3 x AC 400–480 V (±10%), 50–60 Hz, and a control voltage of 230 V AC (±10%), this unit is specified for a rated current of 300 A. It supplies a continuous current of 141 A at 4 kHz and 110 A at 8 kHz, with heat dissipation rated at 1.8 kW. The controller includes an integrated air-cooling blower, bleeder configuration, and supports digital servo/ resolver feedback. Command communication is via the SERCOS interface.

Frequently Asked Questions

How does the SERCOS interface improve control performance in the DKR02.1-W300B-BE23-01-FW?

It enables deterministic, high-speed communication between the controller and automation devices. This reduces latency in motion commands and ensures precise synchronization in multi-axis systems.

Why is a bleeder circuit included in this drive controller?

The bleeder safely dissipates excess regenerative energy during braking cycles. This protects both the motor and controller from overvoltage conditions in dynamic applications.

What type of industries typically require a controller rated for 300A current capacity?

Heavy-duty sectors like metal forming, printing, and packaging rely on such ratings to handle high-inertia loads. These applications demand rapid torque delivery and continuous high current draw.

How does the DKR02.1-W300B-BE23-01-FW support regenerative braking applications?

The integrated bleeder allows energy dissipation when motors decelerate quickly. This avoids the need for external braking resistors in many setups.

What environmental conditions must be considered when installing a blower-cooled drive controller?

Dust, oil mist, or corrosive air can clog or degrade the blower system. Filters or sealed cabinets are recommended for harsh industrial environments.
