KDA 3.1-150-3-AP0-W1

Product Description:

The KDA 3.1-150-3-AP0-W1 comes from Bosch Rexroth Indramat and drops right into the KDA Spindle Drives lineup for machine builders. This drive shows off a rated output current of 150 Amps and handles up to three axes side by side. Size isn’t wasted here—the whole thing is made as a plug-in module, so it slides neatly into assemblies without much fuss about footprint. Cooling uses air with help from an integrated fan, letting everything run smooth even during busy shifts. Power supply runs on 3-phase 380–480 VAC, which covers places that want consistent, beefy input without hiccups.

Working with Indramat AC servo motors fits its style, and feedback runs through either resolver or encoder—so motion control lines keep accurate, no drifting off-point in the middle of cycles. The current-controlled|| mode takes care of adjusting torque control quickly when jobs shift motor loads. For connections, analog and digital are both supported, so different types of system setups sync just fine. The < here sits at IP20, mainly to keep fingers and dust away from the busy internals. The unit weighs approx. 22 kg, and moving it into a cabinet of other servo drives doesn’t throw off the whole layout thanks to the plug-in configuration.

Factories dealing with tough multi-axis jobs often end up with rows of these for spindle or axis motion, especially since each one holds the output steady at 150A. Installation takes less time by design, not just because it plugs in, but the air-cooled fan keeps uptime high, lowering mid-shift interruptions. In heavier automation where three servo axes need to move at the same time, this model steps up. As the industrial day stretches on, there’s no sudden loss of speed—the built-in fan takes the heat, and the 3-phase supply keeps output balanced shift after shift.
