Product Description:
The KDA 3.2-100-3-APS-U1 AC main spindle drive is ideal for applications that require precise control over spindle speed and placement. This drive is designed to be integrated into industrial automation systems. The spindle drive operates on an analog ±10V speed command input.
A DC bus voltage of 300 V is utilized by the KDA 3.2-100-3-APS-U1 AC main spindle drive. The digital microcomputer control allows for integrated position and speed regulation. The drive can handle spindle placement, C-axis control, and drive operations. The drive can transmit location, speed, and torque values using real-time SERCOS communication. Forced airflow through a specialized heatsink blower is used as the cooling approach. With derated operation, the temperature can reach up to 55 degrees Celsius, while the working temperature range is between 5 and 45 degrees Celsius for optimal performance. Installations that are longer than one thousand meters are required to comply with a derating requirement. The drive meets humidity classification F (DIN 40 040), which requires no condensation, and the drive has a maximum relative humidity of 70%. In accordance with the International Standard (DIN) 40 050, this spindle drive does not offer water resistance; nevertheless, it does offer protection against solid objects that are larger than 50 millimeters.
A rated current of 100A is something that the KDA AC spindle drive is able to withstand. Accurate spindle placement and reliable feedback transmission are both made possible by the organization's architecture. On the main spindle drive, there is a protective class that prevents debris from entering during operation. The KDA 3.2-100-3-APS-U1 AC main spindle drive is built to provide reliable performance according to the specified parameters and may be easily integrated into automation systems that meet specific operational and environmental standards.
Frequently Asked Questions about KDA 3.2-100-3-APS-U1:
Q: Why does KDA 3.2-100-3-APS-U1 use forced heatsink cooling?
A: The cooling ensures stable thermal management under high load. It prevents performance loss at elevated temperatures and maintains operational efficiency during continuous rated current delivery.
Q: How does KDA 3.2-100-3-APS-U1 benefit from a 300 V DC bus?
A: The 300 V bus voltage enables efficient power delivery to the spindle motor. It supports rapid torque response and stable speed regulation across operational ranges.
Q: Why does KDA 3.2-100-3-APS-U1 have a humidity classification of F?
A: The humidity classification F ensures durability in high moisture conditions. It allows operation with up to 70% average monthly relative humidity without performance degradation.
Q: Does KDA 3.2-100-3-APS-U1 support position and speed integration?
A: Yes, it integrates both controls in one system. This design reduces external hardware needs and enables synchronized motion control for spindle and C-axis operations.
Q: How does KDA 3.2-100-3-APS-U1 handle altitude derating?
A: The drive maintains full performance up to 1000 m altitude. Above this, derating protects components and ensures safe operation under reduced air density conditions.
