KDA 2.1-050-3-D00-U1

Product Description:

The KDA 2.1-050-3-D00-U1 from Bosch Rexroth Indramat sits in the KDA Spindle Drives group and gets picked often for working on systems that expect a lot of movement and serious current output. This drive eats up a three-phase tube of 220/230/240 V AC input, and spits out a continuous current of 50 A with a spike allowance of 100 A when things get heavy. Mounting is set up for panels, making it easier to access if checks or swaps need to happen. The whole package weighs about 14 kg, built pretty compact with 390 mm height, 110 mm width, and 360 mm depth, so tight cabinets aren’t a problem.

Here's where the air blows through — external air cooling handles temperatures, which matters for setups running around the clock. Overload trouble doesn’t stick around either, with the built-in integrated electronic overload protection keeping the part safer against sudden surges or long strain. Frequency handles either 50 or 60 Hz for power, letting it plug in practically anywhere. The whole unit is shielded up to protection category IP 10, which works fine if the panel stays dry and doesn’t have big splashes to fight with.

Connection and control are straight to the point, supplied with the SERCOS interface so it links well to wider industrial systems and talks to automation without a hitch. There's only one axis to control, which makes it better for spindle jobs where direct and constant torque matter more than running lots of separate tasks. For harsh temperature areas, the range goes from 0°C up to +45°C, keeping performance stable in warmer and cooler climates. The KDA model shines best in drive panels for CNC and industrial machine builds—right where steady current, heating control, overload protection, and low-fuss mounting save time and trouble all year long.
