DKR02.1-W200N-BE43-02-FW

How does the rigid DC bus in the DKR02.1-W200N-BE43-02-FW affect system integration?

It requires external braking solutions if energy feedback occurs, since no internal bleeder or chopper is present. This design simplifies power electronics but shifts energy handling to external components.

Why is resolver feedback supported alongside digital servo feedback?

Resolvers provide robust position feedback in harsh environments where encoders may fail. The dual compatibility increases flexibility for retrofits and mixed system designs.

What does the rated current of 200 A imply for motor selection?

It determines the maximum continuous load the drive can supply to a motor. Motors with similar current demands can be matched to achieve stable torque output.

Does the DKR02.1-W200N-BE43-02-FW require external braking resistors?

Yes, if regenerative energy is expected during deceleration cycles. Without them, excess energy cannot be dissipated safely.

How does the absence of a brake chopper influence regenerative operation?

Regenerated energy must be directed back to the supply grid or handled externally. This makes it important to evaluate the application’s duty cycle for braking events.
