The R911279681 (DKR03.1-W100N-BE93-01-FW) is a drive controller from the Bosch Rexroth DKR series designed for industrial automation. It is specified for operation at ambient temperatures from +5°C to +45°C and supports installation altitudes up to 1000 meters, tolerating a maximum temperature of +55°C. Power input is via a 3-phase AC supply (400–480V, 50–60 Hz) with 230V control voltage. The unit provides a continuous power output of 26 kW at a continuous current of 71 A and supports a 4 kHz drive frequency. Key features include SERCOS command interface, digital servo and resolver feedback, five interface slots, a basic DKR03.1-W100-B unit, air cooling via a built-in blower, IP20 protection, and a continuous regenerated power supply of 22 kW with 900 W heat dissipation. This configuration does not include a bleeder or brake chopper.

Frequently Asked Questions

Does Bosch Rexroth DKR03.1-W100N-BE93-01-FW motor drive sustain thermal stability at maximum 55 °C ambient conditions?

Yes, the built-in blower regulates airflow, dissipating up to 900 W heat load, sustaining controlled thermal behavior during prolonged motor duty cycles at elevated ambient levels.

Where does Bosch Rexroth DKR03.1-W100N-BE93-01-FW motor voltage tolerance ±10% safeguard critical drive inputs?

It compensates for grid fluctuations by stabilizing intermediate circuit voltages, ensuring motor torque regulation remains consistent under transient power disturbances or slight overvoltage drops.

What motor wiring specifications apply when using Bosch Rexroth DKR03.1-W100N-BE93-01-FW with three-phase AC 480V lines?

The unit demands shielded copper conductors rated for industrial insulation categories, reducing electromagnetic interference and maintaining safe conduction during motor acceleration phases.

How does Bosch Rexroth DKR03.1-W100N-BE93-01-FW motor slot allocation support additional functional modules?

Its five internal slots accommodate communication, feedback, or auxiliary control cards, enabling motor integration flexibility across multi-axis machine automation topologies.

What motor insulation coordination does Bosch Rexroth DKR03.1-W100N-BE93-01-FW enforce under IP20 conditions?

IP20 limits ingress to solid objects, so motor terminals require additional enclosure protection in dusty or moisture-prone environments to ensure insulation integrity.
