Product Description:
The KDA 3.2-100-3-L0D-U1 Main Spindle Drive comes with a robust electrical framework that ensures reliable performance in high load scenarios. Its enclosure ingress protection rating of IP 20 shows it is suitable for controlled environments where external sealing is not needed. It can effectively manage substantial load power as it is rated for current up to 100 amperes.
The KDA 3.2-100-3-L0D-U1 main spindle drive uses an air cooled cooling method which guarantees effective management of temperature and does not complex liquid cooling systems. Its build design contributed to easier maintenance and a more compact system. It functions in an environmental temperature between 0 to 45 degrees C that makes it suitable for automation environments where reliable performance is required. Its system control is improved by the digital 16 bit parallel speed command value that allows for precise and responsive changes in speed. It accepts an input voltage of 3 x 220-230, 380-460 V AC which makes it flexible for operating across varied power supply standards. Its design supports superior dynamic performance and operational versatility because of its advanced features like high stiffness, high positioning capabilities and an extensive range of speed. It has no auxiliary encoder input and its analog interface control type further improves compatibility with common control systems.
This KDA 3.2-100-3-L0D-U1 main spindle drive 22 kilowatts rated power helps provide the required capacity to manage robust industrial operations. It comes with safety features like integrated diagnostics and protection circuits that help monitor performance continuously. Its heatsink blower needs 115 volts AC supply source which helps improve its lifespan through an effective thermal management. This module's DC bus voltage of 300 V offers a robust electrical framework for consistent delivery of energy.
Frequently Asked Questions about KDA 3.2-100-3-L0D-U1:
Q: What type of maintenance is simplified by the air-cooled design of the KDA 3.2-100-3-L0D-U1?
A: Air-cooling eliminates the need for liquid cooling circuits, reducing potential leaks and pump failures. It mainly requires periodic cleaning of airflow paths and inspection of the blower.
Q: How does the 16-bit parallel speed command improve spindle performance?
A: It enables high-resolution speed control, allowing smoother spindle acceleration and deceleration. This reduces overshoot and enhances accuracy in high-precision machining operations.
Q: What installation considerations apply for using the drive in environments near 45°C?
A: Adequate ventilation or forced air circulation is required to prevent overheating. Clearance around the unit should be maintained to allow proper airflow.
Q: How does the KDA 3.2-100-3-L0D-U1 handle compatibility with multiple supply voltages?
A: Its wide input voltage range allows flexible installation in regions with either 220/230 V or 380/460 V grids. This minimizes the need for external transformers.
Q: Does the absence of an auxiliary encoder input limit control options?
A: Yes, it restricts certain closed-loop feedback methods that rely on external encoders. However, it simplifies wiring and suits applications where spindle encoder feedback is sufficient.
