Product Description:
The KDA 3.2-050-3-AQ0-W1 is a spindle drive produced by Bosch Rexroth Indramat for the KDA Spindle Drives series. As a drive module, it supplies regulated three-phase power to high-speed machine tool spindles, translating velocity commands from a CNC or PLC into precise motor currents that help maintain torque under load. In typical use, the module supports stable spindle operation during cutting, drilling, and milling processes where demand can change quickly. The series 3 and version 2 codes identify the product generation within the KDA platform, which supports compatibility with companion supply units and feedback cards used in industrial machining centers and automated production cells.
The drive is energized from a DC bus rated at 300 VDC, allowing it to share a common supply with other Indramat axes. Under continuous operation, it can deliver 50 A of output current, providing sufficient current capacity for medium-frame induction or synchronous spindles. An auxiliary single-phase feed of 220 V/50-60 Hz powers the integral heatsink blower so thermal load is removed without taxing the main bus. Reliable function is maintained within an ambient range of 5 °C to 45 °C, which helps keep component temperatures stable on the factory floor. Installation altitude is limited to 1000 m above sea level because reduced air density lowers blower cooling performance.
Cooling hardware consists of a mounted heatsink blower that forces air through the fin stack, and this method is classified as forced cooling. Because the speed loop accepts an analog speed command, the unit can integrate directly with legacy control boards that output ±10 V references. The drive uses a standard terminal-strip interface, so diagnostic signals remain on fixed wiring connections rather than an added communication expansion port. This arrangement keeps control connections straightforward inside enclosed machine cabinets.
