Product Description:

Bosch Rexroth Indramat makes the KDA 3.1-150-3-DPS-W1 spindle drive, which is designed for high-performance spindle control in industrial settings. This unit is part of the KDA Spindle Drives series and can generate a maximum current of 150 A. It has a forced-air cooling system that keeps the unit running smoothly even when it is being used continuously or heavily. It has a SERCOS transmission connection that makes communication and integration easier in current automation systems, therefore it may be used in sophisticated production settings.

The KDA 3.1-150-3-DPS-W1 is housed in an IP20-rated enclosure, which makes it safe to use in regulated situations. It also has a built-in recharge circuit to help with dependable power management. The drive can work at temperatures between +5° and +45°C, but it can only work at its best up to +55°C. However, it will lose power beyond that, as explained in the technical documentation. The manufacturer's instructions say that installation is best done at heights up to 1,000 meters above sea level, however performance drops at greater heights are explicitly explained. The device is built to handle humid situations according to Humidity Classification F (DIN 40 040).

This means it may be used in workshops with different climates as long as the average relative humidity doesn't go beyond 70% and condensation doesn't happen. The drive's enclosure is certified IP10 per DIN 40 050, which means it can protect against items bigger than 50 mm but not against water getting in or intentional contact. To be completely safe, the drive must be installed in a separate control enclosure or sealed housing. The KDA 3.1-150-3-DPS-W1 is designed to let heat escape via its housing air vents and a heatsink on the back.
