KDA 2.1-050-3-DP0-U1

Product Description:

The KDA 2.1-050-3-DP0-U1 spindle drive is built for tough, nonstop work and comes from Bosch Rexroth Indramat’s KDA Spindle Drives family. Current rating goes up to 50A, letting the unit push plenty of power to heavy-duty machine tool spindles and also stand solid under unpredictable shop conditions. With a design for 3-phase, 220-230V AC input, the setup stays stable even if the mains see a bit of voltage swing now and then. The hardware is organized for 3 axes—that means easy enough handling for setups needing multiple movements or coordinated work positioning.

When cooling matters for longevity, the drive gets it done by running with internal air cooling, built right in, to take care of heat before it stacks up. Mounting goes panel-side, so installation into enclosures or machine cabinets lines up smooth—no odd bracket patterns or outside attachments. The digital control type sits at the core, keeping position and speed sharp, with quick changes and clean accuracy on each spindle cycle. Each detail around interface lands on SERCOS, making automation tie-in easy for shops using modern data controls, so no extra adapters or dealing with out-of-date serial gear. Protection supports this feel too, tossing dust or stray swarf aside with an IP20 enclosure rating built on standard shop housing.

Weight checks in at 32 kg, so the drive works with heavy pieces but doesn’t strain most cabinets or frames. Dimensions reach 390mm by 450mm by 365mm, which fits with most panels or drive banks in an industrial cell. Electrical modules take DP0 (Profibus-DP) for communication, so integration into shop networks doesn’t start a headache. The mix of air cooling, digital interface, and spill-resistant case covers all sides, and all parts are from the kind of tough builds Bosch Rexroth Indramat stays known for.
