The R911270963 (DKR03.1-W200Z-BE45-01-FW) is a Rexroth Indramat DKR03.1 series drive controller engineered for monitoring and controlling AC main spindle, frameless spindle, and linear motors. The device integrates a SERCOS interface for command input and supports both digital servo and resolver feedback for precise motor control. It operates with a control voltage of AC 230 V (±10%) and a rated power voltage of 3xAC 400 to 480 V (±10%), with a rated current of 200 A. The unit includes an integrated mains contactor, emergency stop function, and firmware module. Cooling is provided by a built-in blower. Its operational parameters include an ambient temperature range of +5°C to +45°C, installation altitude up to 1000 m, and an approximate weight of 49 kg. Optionally, a brake resistor and auxiliary plug-in modules can be added.

Frequently Asked Questions

What does the SERCOS interface on the DKR03.1-W200Z-BE45-01-FW enable?

It allows high-speed, standardized communication between the controller and automation systems. This ensures precise synchronization of drives in multi-axis applications.

Why is resolver feedback supported alongside digital servo feedback?

Resolver feedback provides reliable position data in harsh conditions. Digital servo feedback offers higher resolution where fine accuracy is required.

How does the line series 03 influence compatibility with other drives?

It defines firmware and interface standards for that generation. Matching series ensures seamless integration across multi-drive systems.

Can the DKR03.1-W200Z-BE45-01-FW be used in spindle drive applications?

Yes, its current rating and feedback options suit high-speed spindles. Proper tuning of control parameters is required for stability at maximum RPM.

What happens if airflow to the built-in blower is restricted?

Insufficient cooling can lead to thermal shutdown or shortened component life. Regular cleaning of filters and ducts prevents this risk.
