DKR02.1-W300B-BE41-02-FW

What does the built-in bleeder in the DKR02.1-W300B-BE41-02-FW do during operation?

It dissipates excess regenerative energy from the motor into heat, preventing overvoltage conditions. This ensures stable performance in applications with frequent braking cycles.

Why is air cooling with a blower chosen over liquid cooling in this controller?

Air cooling reduces complexity and installation cost compared to liquid-cooled systems. It is effective when mounted in properly ventilated control cabinets.

Can a 300 A current rating handle high-inertia load applications effectively?

Yes, the high current capacity enables strong torque output to accelerate and decelerate heavy loads. This is particularly useful in presses, extruders, or large conveyors.

What risks occur if the built-in blower is obstructed during operation?

Restricted airflow causes overheating, reducing efficiency and potentially triggering thermal shutdowns. Proper clearance and regular dust cleaning are required.

What is the practical effect of using this controller with digital servo feedback in CNC machinery?

It allows precise axis positioning with minimal lag, critical for milling and cutting tolerances. This improves surface finish and repeatability in production.
