The R911266197 (DKR02.1-W300N-BE23-01-FW) is a drive controller from Bosch Rexroth designed for use in industrial motion control systems. It is powered by a three-phase AC supply at 400–480 V and includes an integrated mains contactor. This unit supports a nominal output current of approximately 300 A and operates effectively with a 4/8 kHz switching frequency. It supports continuous regenerated power of 43 kW and a peak regenerated power of 93 kW. Communication with connected systems is managed via a SERCOS interface, while motor feedback utilizes both digital servo and resolver options. The controller is configured through specific numeric codes and provides IP20 ingress protection. Cooling is achieved using a built-in blower, and the device is specified for operating temperatures between +5°C and +45°C at altitudes up to 1000 meters. No bleeder or brake chopper is integrated; it features a rigid DC bus.

Frequently Asked Questions

Why is resolver feedback included alongside digital servo feedback in the DKR02.1-W300N-BE23-01-FW?

Resolver feedback provides robust position detection in harsh environments. This redundancy enhances reliability when precise motor positioning is critical.

How does the lack of a brake chopper in the DKR02.1-W300N-BE23-01-FW affect performance?

Without a brake chopper, energy is returned through the DC bus instead of dissipated as heat. This improves efficiency but requires stable system integration.

How does the Function Numeric Version 01 firmware benefit operation?

This firmware includes built-in motion algorithms for faster commissioning. Users benefit from advanced motion profiles without requiring custom programming.

Why is a blower-based cooling method used in the DKR02.1-W300N-BE23-01-FW?

The blower provides forced air circulation to maintain safe operating temperatures. This cooling method allows the unit to perform reliably during continuous heavy-duty cycles.

What role does the SERCOS interface play in synchronization?

The SERCOS interface ensures real-time, deterministic communication. This enables precise coordination across multiple axes in complex automation setups.
