DKR04.1-W300E-BE12-01-FW

Why does the DKR04.1-W300E-BE12-01-FW require an external bleeder with brake chopper?

The external bleeder dissipates regenerated energy during braking, preventing DC bus overvoltage. This ensures safe deceleration in applications with frequent stops or reversals.

How does resolver feedback differ from digital servo feedback in this controller?

Resolver feedback provides robust position sensing in harsh conditions, while digital servo feedback enables higher precision. The combination supports a wide range of motors and accuracy requirements.

What installation considerations are necessary for handling approx. 300A nominal current?

Cabling, connectors, and protective devices must be sized to handle high current safely. Proper busbar design and grounding are also essential to prevent overheating and electrical noise.

How does the rigid DC bus design affect overall system stability?

A rigid DC bus improves voltage stability under dynamic loads. It reduces the risk of fluctuations that can impact motion accuracy or cause system faults.

Can the DKR04.1-W300E-BE12-01-FW be used in CNC machining systems?

Yes, it is suitable due to its fast command processing and feedback handling. This allows precise motor control for cutting, milling, and multi-axis positioning.
