Product Description:
The KDA 3.2-100-3-A0D-U1 spindle drive is produced by Bosch Rexroth Indramat for the KDA Spindle Drives series. As a drive controller, it converts a fixed DC bus into variable three-phase output to run high-speed spindle motors used in machining centers, grinding cells, and other metalworking equipment. The unit integrates into Indramat multi-axis systems where coordinated spindle speed is required for precise cutting and tooling operations.
The drive operates from a DC link voltage of 300 VDC and can deliver up to 100 A of continuous output current, making it suitable for medium-to-large spindle applications. Thermal management uses a mounted heat-sink blower that pushes air across the power module, and airflow is supported by a dedicated 115 V/50-60 Hz auxiliary supply. Because the internal ducts rely on forced cooling, the unit can dissipate heat effectively during prolonged high-speed cuts. Speed reference data arrives as an analog voltage, while the machine CNC can also send a digital position command value through the additional interface when contouring accuracy is required. A second encoder input is not provided, so external phase-locked feedback devices must connect directly to the master controller. This variant is series number 3 and version 2 within the KDA family.
The drive maintains full ratings at ambient temperatures from 5 to 45 degrees Celsius, allowing it to share enclosures with other heat-generating axes without derating. Installation is permitted up to 1000 m above sea level, which covers most industrial sites without special cooling adjustments. The heat-sink blower draws filtered shop air, so particulate control in machining cells should suit this cooling method. These operating limits support stable current delivery and consistent command response during extended production use.
