Product Description:

The KDA 3.2-100-3-L0I-W1 spindle drive from Bosch Rexroth is a reliable solution designed for industrial applications and is known for producing high-quality motion control components for precise and efficient operations. It is engineered to deliver a rated current of 100 A which ensures stable operation in demanding environments.

The KDA 3.2-100-3-L0I-W1 spindle drive has a DC Bus voltage rated at 300 V which supports consistent power delivery to the connected motor systems. By using a heatsink blower to force cooling, safe operating temperatures are maintained throughout continuous operation. The heatsink is powered by a 220 V AC supply source with a frequency range of 50 to 60 Hz to comply with conventional power regulations. The KDA Spindle Drives support speed command value through the SERCOS-Interface which allows precise control in automated processes. An auxiliary interface is provided with an incremental encoder output for improved monitoring and feedback. This model supports mechanical installation through the accessories kit M1-KD which makes mounting straightforward and secure. Without sacrificing performance, it may be installed up to 1000 meters above sea level. Its compatibility with industrial automation systems and adherence to technical standards make it a suitable choice for manufacturing and machining operations requiring accurate and stable spindle control. The humidity class is rated F which confirms reliability in moderately humid conditions.

The KDA 3.2-100-3-L0I-W1 spindle drive has a transportation temperature range is -30 to +85 °C which enables safe shipment and storage in varying conditions. The operating ambient temperature is appropriate for a variety of working conditions and ranges from +5 to +55 °C. The KDA 3.2-100-3-L0I-W1 spindle drive provides reliable service because of its accurate control interface and efficient thermal management.

Frequently Asked Questions about KDA 3.2-100-3-L0I-W1:

Q: Why does the KDA 3.2-100-3-L0I-W1 spindle drive use a 300 V DC Bus voltage?

A: The 300 V DC Bus ensures efficient and consistent power delivery to motors. It reduces energy loss and supports high-speed spindle operation.

Q: How does the SERCOS interface improve performance in KDA 3.2-100-3-L0I-W1 spindle drive?

A: The SERCOS interface enables real-time communication for high-speed feedback. This allows precise synchronization with motion control systems.

Q: What role does the auxiliary encoder output play in this spindle drive?

A: The auxiliary encoder output offers real-time position and speed feedback. This helps in monitoring and adjusting spindle behavior dynamically.

Q: Why is the KDA 3.2-100-3-L0I-W1 spindle drive designed for use up to 1000 m elevation?

A: The drive is optimized to maintain cooling and electrical characteristics up to 1000 m. This avoids derating or overheating in elevated installations.

Q: How does forced cooling by heatsink blower improve system longevity?

A: The forced-air cooling system prevents thermal overload by continuously dissipating heat. This ensures longer operational life and reduces failure risk.
