DKR04.1-W300

Can the DKR04.1-W300 be used in multi-axis systems?

Yes, but its cooling and power draw may require dedicated space and airflow planning in cabinets. Multi-axis integration must account for its high current consumption.

Why is the bleeder marked as factory-assigned?

This ensures the drive’s braking resistor is matched to its internal design for energy dissipation. Field modifications are not recommended, as mismatched resistors may cause overheating.

What precautions are needed when mounting the DKR04.1-W300 vertically?

Vertical mounting can restrict airflow if spacing rules are not followed. A minimum clearance above and below the unit is required to prevent hot air recirculation.

How does the current rating influence cable selection?

The 300A rating requires appropriately sized conductors to minimize voltage drop and heating. Incorrect cable sizing can trigger overcurrent trips or degrade insulation.

What role does factory-assigned motor feedback play?

It ensures compatibility with specific encoder or resolver systems pre-configured for the drive. This avoids tuning issues but may limit interchangeability with third-party motor
