The R911296455 (DKR05.2-W500N-BE12-01-NNSN-FW) is a Rexroth Indramat drive controller designed for use in digital intelligent drive systems in industrial equipment such as printing machines, handling systems, machine tools, and robotics. It supports direct connection to a three-phase power supply (50/60 Hz), offering switching frequencies of 4 kHz and 8 kHz and continuous power outputs of 93 kW and 66 kW, respectively. Key specifications include 500 A nominal current, 165 kW rated motor power at 400 V, and 6.2 kW power dissipation. The unit includes configurable plug-in modules, SERCOS interface, digital servo and resolver feedback support, and a firmware module for parameter storage. Cooling is provided by a built-in air blower. It features a main switch on the door, lock compatible with a 7 mm three square socket wrench, rigid DC bus without bleeder, and is finished in pebble gray. The controller operates in ambient temperatures from +5 to +45 °C and has an IP20 protection rating. Weight is 550 kg.

Frequently Asked Questions

Does the DKR05.2-W500N-BE12-01-NNSN-FW support high-speed communication with controllers?

Yes, it uses the SERCOS command interface, which provides deterministic and high-speed data exchange. This allows synchronized motion control across multiple axes in automation systems.

How does the 6.2 kW power dissipation affect the DKR05.2-W500N-BE12-01-NNSN-FW’s performance?

Efficient heat management keeps the system stable under continuous high-current operation. This minimizes overheating risks and extends the drive’s operational reliability.

Do the digital servo and resolver feedback systems enhance motion accuracy?

Yes, they provide real-time feedback for speed and position, enabling precise control. This results in smoother motor response and higher production accuracy.

How does the built-in blower cooling system benefit the DKR05.2-W500N-BE12-01-NNSN-FW during operation?

The blower cooling maintains an optimal temperature range, even during extended load cycles. It helps prevent component stress and ensures consistent drive efficiency.

Why is the nominal current of 500 A significant in the DKR05.2-W500N-BE12-01-NNSN-FW?

It enables the drive to handle high torque demands without performance degradation. This capacity supports the operation of powerful industrial motors under heavy loads.
