DKR02.1-W300B-BA03-01-FW

What cooling setup is required when installing the DKR02.1-W300B-BA03-01-FW?

It uses an integrated blower, so no external cooling circuit is needed. However, sufficient airflow clearance must be ensured in the cabinet to avoid overheating.

Can this unit handle both resolver and digital feedback devices simultaneously?

It can be configured to support either type, depending on the motor feedback requirements. The choice impacts positioning accuracy and compatibility with specific motors.

What is the role of the bleeder circuit in this controller?

The bleeder dissipates regenerated energy from braking into heat, protecting the DC bus from overvoltage. This makes it suitable for applications with frequent starts and stops.

Does the DKR02.1-W300B-BA03-01-FW require external braking resistors?

No external resistors are needed since the internal bleeder manages regenerative power. For extremely high dynamic loads, external options may still be considered.

What considerations should be made when mounting this controller in an enclosure?

Proper spacing for air circulation is critical since it relies on forced internal air cooling. Dust filtration should also be considered to protect the blower and electronics.
