KDA 3.2-100-3-A0D-U1

The Bosch Rexroth Indramat KDA 3.2-100-3-A0D-U1 controller is part of the KDA Spindle Drives series, designed and manufactured by Bosch Rexroth Indramat. It features a current rated of 100 A and a continuous current of 70 A, delivering robust and reliable power handling for demanding spindle applications. With a rated voltage of 300 V and a DC bus voltage matching its continuous power output, this drive controller is engineered to manage precision motion control in metalworking and machining centers. Its primary function is to regulate and optimize the speed and torque of high-speed spindles, ensuring consistent performance under variable load conditions.

The technical core of the KDA 3.2-100-3-A0D-U1 includes an Analog +/- 10V Speed Command Value interface that allows fine adjustment of spindle speed via standard voltage signals. Forced cooling is provided by an integrated heatsink blower, with a rated connection voltage for attached blower of AC 50–60 Hz, maintaining thermal stability even under peak output. The drive design “2” chassis supports a modular approach, combining the main power section with auxiliary components such as encoder interfaces. Its streamlined layout and robust heatsink assembly ensure efficient heat dissipation, critical for continuous spindle operation at high rotational speeds.

Additional features include an Aux. Encoder Input specified as «WithoutAux. Interface1», enabling compatibility with external feedback systems where required. The compact design of the KDA 3.2-100-3-A0D-U1 drive controller enhances its durability, while forced-air cooling extends component life in industrial environments subject to dust and temperature fluctuations. Conforming to standard drive-controller safety and performance guidelines, it excels in high-stiffness positioning applications and broad speed ranges. In industrial machining, the benefits of using this spindle drive include improved cycle times, precise torque control, and enhanced process stability, reinforcing its role as a critical component in advanced manufacturing setups.
