The R911284828 (DKR02.1-W300B-BE76-01-FW) is a drive controller from the Indramat DKR series, designed to operate with a 3-phase AC supply voltage of 400–480V and an AC 230V control voltage. It offers a continuous power output of 55/43 kW at a rated current of 141/110 A, with a switchable frequency between 4 and 8 kHz. The controller supports digital servo and resolver feedback for motor control, and enables communication via a SERCOS interface in the U1 slot. This unit, with air cooling provided by an integrated blower, dissipates 1,800 W of heat (1,200 W released via blower). The built-in bleeder resistor can absorb up to 240 kWs, and connections are provided for motor temperature monitoring and a holding brake. The enclosure meets IP20 protection standards, and the unit has an approximate weight of 104 kg, excluding additional components.

Frequently Asked Questions

What is the impact of the 300 A current capacity on motor applications?

It allows driving larger servo motors with steady torque output. This makes it suitable for machinery that requires high force and precision motion simultaneously.

How does the DKR02.1-W300B-BE76-01-FW handle thermal management in continuous operation?

It uses an integrated blower for direct air cooling, reducing heat buildup. This ensures stable performance under heavy load without relying on external cooling systems.

How does dual feedback (resolver and digital servo) benefit motion control?

It enables accurate position tracking while allowing adaptive tuning. This improves performance in applications with varying loads or high dynamic demands.

How does the SERCOS interface affect system communication?

It provides deterministic real-time data exchange between drives and controllers. This ensures synchronization critical in multi-axis machine setups.

How does built-in blower cooling affect long-term maintenance?

It reduces dependency on external fan assemblies that often require servicing. This lowers downtime and overall maintenance costs across production cycles.
