The R911286211 (DKR03.1-W200N-BT49-01-FW) is a drive controller from the Rexroth Indramat DKR series, engineered for the monitoring and control of electric motors including ADF/2AD main spindle motors, linear motors, and 1MB frameless spindle motors. It operates on a grounded 3xAC 400–480 V supply and features an air-blower cooling system in the integrated housing. The drive supports SERCOS communication, digital servo and resolver feedback, delivers 92 A continuous current at 4 kHz or 78 A at 8 kHz, has a peak power output of approximately 55 kW, and maintains continuous regenerated power around 30 kW. The configuration is specified as rigid DC bus, with no bleeder or brake chopper integrated. The firmware is stored on an internal EPROM.

Frequently Asked Questions

What is the impact of using air cooling in the DKR03.1-W200N-BT49-01-FW?

Air cooling requires proper airflow clearance in the cabinet, making installation design critical. It simplifies maintenance compared to liquid cooling but limits use in dusty or high-temperature environments.

How does a SERCOS interface affect system integration?

SERCOS provides deterministic communication with precise synchronization of multiple axes. This ensures predictable motion control performance in automated systems.

What role does the function numeric version (01) play in system configuration?

It defines the drive’s feature set and firmware alignment within the series. This helps engineers match drives across projects while maintaining consistent behavior.

What housing class does the DKR03.1-W200N-BT49-01-FW use, and what does it mean for installation?

The IP20 housing protects against accidental contact but not against dust or liquids. This means the unit must be installed inside a protected cabinet or enclosure.

How does rigid DC bus design influence energy management?

It eliminates onboard braking choppers, so DC bus energy remains within the system. This is efficient for shared DC link systems but less flexible for standalone regenerative braking.
