Product Description:
Bosch Rexroth makes the KDA 3.1-100-3-LQ0-U1, which is an AC main spindle drive used to precisely control spindle motors in industrial automation applications. For demanding drive tasks, it is made to work reliably and effectively. The product can handle a DC bus voltage of 300V and has a maximum current of 100A. Its interface is built on SERCOS, which makes control and communication easy.
The maximum temperature that the KDA 3.1-100-3-LQ0-U1 main spindle drive can handle is +55°C, and the temperature range for normal use is +5°C to +45°C. A heatsink blower, driven by a 115V AC supply at 50-60Hz, cools it down. The spindle drive has an extra encoder input that works with 1V sinusoidal encoders. The drive has an IP 10 security rating, which indicates that it is protected against objects with a diameter of more than 50 millimeters without any problems. Additionally, the spindle drive is designed to be able to conform to control boxes or housings that are totally hermetically sealed. The device can function in environments with an average humidity level of less than 70 percent; nonetheless, it is imperative that precautions be taken to prevent moisture. A temperature-dependent decrease diagram shows how the drive values will be lowered if the temperature outside goes above 45°C.
The highest point at which the KDA 3.1-100-3-LQ0-U1 main spindle drive can be installed is 1,000 meters above sea level. It also includes a source of AC power for the heatsink fan. Because it is made to work well in mild climates, the drive considers both high and low ambient temperatures. For the drive to work for a long time, it needs to be installed and maintained correctly.
Frequently Asked Questions about KDA 3.1-100-3-LQ0-U1:
Q: Does the KDA 3.1-100-3-LQ0-U1 have protection against water?
A: No, the KDA 3.1-100-3-LQ0-U1 has an IP 10 protection rating, meaning it is not protected against water ingress.
Q: How does the KDA 3.1-100-3-LQ0-U1 handle high ambient temperatures?
A: The KDA 3.1-100-3-LQ0-U1 operates effectively in ambient temperatures up to +45°C and can handle peak temperatures of +55°C by reducing its values according to a temperature-dependent reduction diagram.
Q: What is the benefit of the auxiliary encoder input in KDA 3.1-100-3-LQ0-U1?
A: The auxiliary encoder input allows compatibility with 1V sinusoidal encoders, providing precise feedback for accurate motor control and better performance in industrial machinery.
Q: Do I need to consider humidity when operating the KDA 3.1-100-3-LQ0-U1?
A: Yes, it is important to maintain a relative humidity below 70% to avoid condensation, which could affect the unit’s performance and longevity.
Q: How does the KDA 3.1-100-3-LQ0-U1 stay cool during operation?
A: The KDA 3.1-100-3-LQ0-U1 uses forced cooling via a heatsink blower, powered by an external 115V AC supply, ensuring effective heat dissipation during heavy workloads.
