The Bosch Rexroth drive controller, MPN R911268461 (DKR02.1-W300N-BE09-01-FW), is engineered for operation within an ambient temperature range of 5°C to 45°C and features an IP20 protection rating per IEC 529 / EN 60529. It utilizes air cooling with a built-in blower and provides a heat dissipation capacity of 1,200W. The unit must be installed vertically in an enclosed area or cabinet compliant with DIN VDE 0160, using the M2-RAC 2.2 accessories kit. The drive controller supports both digital servo and resolver feedback and utilizes a SERCOS interface for command. It is designed with a rigid DC bus, no brake chopper, and a nominal current of approximately 300A. Maximum motor feedback cable length is 75m; motor power cables should be routed separately in domestic or light industrial zones. To avoid operational issues, maintain sufficient air inlets and outlets and prevent polluted air intake.

Frequently Asked Questions

How does the SERCOS interface improve communication in the DKR02.1-W300N-BE09-01-FW?

SERCOS delivers high-speed, deterministic communication between drives and controllers. This ensures synchronization across multiple axes with minimal latency.

Do resolver feedback options in the DKR02.1-W300N-BE09-01-FW provide any benefits in harsh environments?

Yes, resolver feedback ensures reliable position and speed detection under conditions of electrical noise or temperature extremes. It is often chosen for rugged applications where digital encoders may fail.

Why does the DKR02.1-W300N-BE09-01-FW use air cooling with a built-in blower?

The built-in blower maintains efficient thermal management without external cooling units. This enables compact installation while ensuring long-term performance stability.

Does digital servo feedback in the DKR02.1-W300N-BE09-01-FW improve accuracy compared to traditional methods?

Yes, digital servo feedback provides highly accurate positional data and rapid responsiveness. It allows precise motion control even under dynamic operating conditions.

What advantage does the 300 A nominal current rating give to the DKR02.1-W300N-BE09-01-FW?

The high current capacity enables the drive to power heavy-duty motors effectively. This makes it suitable for applications requiring significant torque output.
