KDA 3.2-100-3-DY0-U1

The Bosch Rexroth Indramat KDA 3.2-100-3-DY0-U1 from the KDA Spindle Drives series delivers robust spindle performance with a rated current of 100 A and a DC bus voltage of 300 V. This Design 2 unit, part of Series 3, integrates a high-precision speed command interface using a Digital 16-bit parallel signal and supports an Auxiliary/Synchronous Encoder Input as standard. Built on the proven KDA platform, the drive is tailored for demanding stiffness and dynamic positioning applications in high-speed machining environments.

Featuring a forced cooling scheme via an integrated heatsink blower, the drive ensures continuous operation under peak loads. The blower operates on an AC supply for heatsink blower of 115 VAC to maintain optimal thermal performance. With no additional auxiliary interface required, installation is simplified and chassis space is conserved. Advanced internal control algorithms exploit the drive’s digital parallel architecture to deliver seamless torque responses across a broad speed range.

Engineered for precision spindle control, the KDA 3.2-100-3-DY0-U1 excels in applications where rigidity, accurate positioning, and continuous power delivery are critical. Its compact footprint and forced-cooling topology make it an ideal choice for both retrofits and new machine tool designs seeking reliable performance.
