The Bosch Rexroth drive controller with MPN R911288596 (DKR02.1-W200B-BA01-01-FW) is designed for industrial automation, delivering up to 55 kW of power with a peak current of 141 A and a rated current of 200 A. It operates directly on 3-phase AC power with a control voltage of 230 V ±10% and accommodates power voltages from 0 to 380 V. The controller features a basic DKR02.1-W200B unit with five slots for plug-in modules, including a SERCOS interface for real-time communication. It provides analog-command input, integrated bleeder support, and supports both digital servo and resolver feedback for precise position measurement. Its switching frequency is user-selectable between 4 kHz and 8 kHz. The unit employs a built-in fan using external air for cooling and features an IP20-rated housing. Optimal operation is specified between +5 and +45 °C and up to 1000 m altitude.

Frequently Asked Questions

How does the bleeder configuration improve stability in DKR02.1-W200B-BA01-01-FW?

The bleeder dissipates excess DC bus energy during regeneration, preventing voltage spikes. This ensures consistent system stability in applications with frequent braking cycles.

What installation considerations should be made for its built-in blower cooling system?

It requires unobstructed airflow and clearance to avoid heat accumulation. Placement in dust-heavy environments may demand additional filtration or maintenance.

Can the analog command interface be integrated with older motion systems?

Yes, it supports legacy analog control signals while remaining compatible with modern automation. This makes it suitable for retrofit scenarios without major system redesign.

How does the 200A rated current impact system design for DKR02.1-W200B-BA01-01-FW?

It supports high-power servo drives, requiring appropriate cabling and protective components. Electrical infrastructure must be sized to handle sustained current levels safely.

What role does modular connectivity play in maintenance?

Front-access terminals and modular wiring reduce downtime during replacements. Maintenance teams can quickly swap units without major rewiring.
