Product Description:

Bosch Rexroth is a famous manufacturer of automation products and motion control equipment. The DDC01.1-K050B-RS55-00-FW is a digital intelligent servo drive. The servo drive is built to deliver a high dynamic response and precise servo motor control.

The DDC01.1-K050B-RS55-00-FW servo drive operates using microprocessor based architecture supporting real time drive regulation and monitoring. The servo drive includes resolver feedback that offers accurate motor position and velocity detection. Its built-in air cooling system enables consistent thermal management during continuous operations. The DDC01.1 servo drive delivers a peak current of 50 A and a continuous current of 25 A which makes it suitable for both high torque and precision demanding applications. The pulse frequency is rated at 8 kHz which ensures smooth motor rotation and low vibration. The drive can operate at input frequencies from 50 Hz to 60 Hz for flexible power compatibility. A built-in bleeder resistor dissipates excess energy when the motor enters braking mode. It handles a continuous bleeder power of 0.25 kW which enhances system stability during rapid stops. Power loss at maximum load is capped at 500 W for excluding the bleeder loss. The DDC01.1-K050B-RS55-00-FW servo drive is housed in an IP65-rated enclosure for protection against dust and water. It can function in rated ambient temperatures between +5°C and +45°C. The servo drive operation is also supported up to +55°C with reduced performance due to thermal derating.

The DDC01.1-K050B-RS55-00-FW servo drive drive can be integrated into factory automation systems, CNC equipment, and robotic machinery. The servo drive is equipped with a SERCOS interface for high speed digital communication. The servo drive allows seamless integration into multi axis control systems and complex motion setups.

Frequently Asked Questions about DDC01.1-K050B-RS55-00-FW:

Q: What role does the 8 kHz pulse frequency play in motor performance?

A: The 8 kHz switching frequency ensures low torque ripple and smoother motor rotation, reducing mechanical stress.

Q: Why is resolver feedback used in DDC01.1-K050B-RS55-00-FW?

A: Resolver feedback provides accurate position and velocity data under harsh industrial conditions, unlike optical encoders.

Q: How does the IP65 protection impact system installation?

A: It allows direct installation in dusty or damp environments without needing extra enclosure protection.

Q: Does the DDC01.1-K050B-RS55-00-FW support regenerative braking?

A: Yes, and the 0.25 kW bleeder ensures that excess kinetic energy is safely converted and dissipated.

Q: Why is thermal derating necessary at higher temperatures?

A: As temperature rises above +45°C, component efficiency drops; derating ensures reliability without overloading circuits.
