The R911325906 (DKR03.1-W200N-BT69-01-FW) is a Bosch drive controller engineered for digital control of Indramat motors, including 2AD, LSF, and 1MB motor series. It operates with a rated power voltage of 3x400-480 VAC, a control voltage of 230 VAC at 50-60 Hz, and supports a peak current of 141 A with a rated current of 200 A. The unit is air-cooled via a built-in blower, with heat dissipation of 1200 W facilitated by an integrated heat sink. Feedback is managed using digital servo and resolver technologies. This Type 1 controller features a SERCOS communication interface and is provided in design version 1, line series 03. The mechanical accessories kit with mounting components is included. Bleeder and brake chopper functions are not present; it is configured for a rigid DC bus. The device has an approximate weight of 49 kg.

Frequently Asked Questions

How does the rigid DC bus in the DKR03.1-W200N-BT69-01-FW affect system stability?

It minimizes voltage fluctuations by absorbing transient loads directly. This improves motion consistency in high-demand multi-axis applications.

What installation considerations come with its built-in blower cooling system?

The unit requires adequate airflow clearance in the cabinet. Dust filtration should be maintained to ensure reliable thermal performance.

Can this controller operate with both digital servo and resolver feedback simultaneously?

Yes, it supports multiple feedback types for flexible motor compatibility. This allows precise tuning across diverse machine configurations.

How does firmware versioning impact motion algorithms in this drive controller?

Each firmware release governs available diagnostic and control features. Consistency in versioning ensures predictable integration across installations.

What industries benefit most from air-cooled controllers like this model?

They suit environments with stable ambient conditions such as packaging and electronics assembly. Heavy-duty, dust-prone plants may require additional enclosure sealing.
