The R911290965 (DKR02.1-W300B-BT67-01-FW) is an industrial drive controller engineered for precision motor control in servo applications. It operates with a closed-loop motor feedback system supporting digital servo and resolver feedback and provides internal self-diagnostics with clear messaging for operational deviations. The controller features a SERCOS command interface and a built-in blower for air cooling. Input voltage ranges from 400 to 480 V; an autotransformer can be used if main supply voltage is insufficient. The bleeder configuration is included, current rating is approximately 300 A, and the total weight is 104 kg plus optional accessory weight up to 1.7 kg. Suitable for operation from +5 to +45°C, the unit is classified as Design Version 1 in the DKR line series.

Frequently Asked Questions

Can the DKR02.1-W300B-BT67-01-FW interface with older servo drives?

Yes, because it supports both resolver and digital servo feedback. This compatibility helps when upgrading mixed-generation automation systems.

Why is the SERCOS interface significant in this controller?

SERCOS enables synchronized real-time communication between multiple drives and controllers. This ensures precise, coordinated motion across complex automation tasks.

Does the design version and line series of the DKR02.1-W300B-BT67-01-FW matter during replacement?

Yes, because compatibility depends on matching version and series. Installing the wrong design could cause firmware or parameter mismatches.

How does resolver feedback differ from digital servo feedback in use?

Resolver feedback is rugged and works well in harsh environments. Digital servo feedback offers higher accuracy where fine positioning is critical.

Can this controller handle frequent stop-and-start cycles in production lines?

Yes, its energy discharge system and current capacity are suited for repetitive cycles. However, proper thermal management must still be ensured.
