Product Description:

Bosch Rexroth Indramat made the KDA 3.1-100-3-DYI-U1 spindle drive. The spindle drive is part of the Series 3 design range and is made for accurate control of spindles in industrial automation. Bosch has designed it with specifications that support reliable operation within the specified environmental and technical restrictions.

The KDA 3.1-100-3-DYI-U1 spindle drive can handle a DC bus voltage of 300 V and a maximum current of 100 A. The value of the speed order is analog and can be between +/-10V. The level of protection is IP 10 according to DIN 40 050, which implies that nothing larger than 50 mm can pass through. Temperatures that fall within the range of +5°C to +45°C are referred to as ambient. The spindle drive is able to continue operating normally even when subjected to temperatures as high as +55 degrees Celsius. In order to operate, the heat sink fan necessitates a 50-60Hz frequency and an AC supply of 115V to chill the unit by force. The highest position where the system can function correctly is 1,000 meters above sea level. This spindle drive has an aux encoder input with auxiliary and synchronous inputs to ensure the drive is properly placed. It also includes an auxiliary interface with an incremental encoder output for improved contact and signal dependability.

The spindle drive is made with a standard build format that is described by a design classification of 1. For stable performance, the KDA 3.1-100-3-DYI-U1 spindle drive is designed with environmental and functional requirements that allow it to be easily integrated into automation systems. The main spindle drive is made with a strong design that makes it work with modern drive technologies.

Frequently Asked Questions about KDA 3.1-100-3-DYI-U1:

Q: How does KDA 3.1-100-3-DYI-U1 maintain cooling efficiency?

A: The unit uses a forced heatsink blower that operates on 115V AC. This ensures continuous airflow and prevents overheating during sustained rated current conditions.

Q: Why do KDA 3.1-100-3-DYI-U1 units specify +55°C peak ambient temperature?

A: The +55°C peak ambient tolerance provides safety margins. It prevents malfunction under sudden temperature spikes and ensures continuous performance during variable operating environments.

Q: How does KDA 3.1-100-3-DYI-U1 benefit from the IP 10 category?

A: The IP 10 protection category prevents the entry of large solid objects. It safeguards drive integrity and maintains functionality without risk of internal obstruction.

Q: Do KDA 3.1-100-3-DYI-U1 units operate reliably at 1,000 m elevation?

A: Yes, the unit operates reliably up to 1,000 meters. This elevation limit ensures stable cooling efficiency and proper power management within standard atmospheric conditions.

Q: Why does KDA 3.1-100-3-DYI-U1 specify an average 70% humidity?

A: The 70% average humidity limit reduces the risk of internal condensation. It ensures insulation reliability and protects sensitive circuits from moisture-related performance failures.
