KDA 3.3-150-3-L00-U1

The KDA 3.3-150-3-L00-U1, Bosch Rexroth Indramat, KDA Spindle Drives controller delivers high-performance spindle regulation in a compact package. Designed specifically for demanding CNC and machine-tool applications, it provides precise current and voltage management across a wide operating window. Bosch Rexroth Indramat’s proven technology ensures consistent motion control, minimal electrical noise, and rapid response to dynamic load changes. The drive’s robust construction and modular architecture streamline integration and simplify maintenance across various automated manufacturing installations.

Featuring a continuous current rating of 90 A and a current rated peak capacity of 150 A, the drive maintains stable torque output under heavy machining loads. It operates at a nominal rated voltage of 300 V and employs forced cooling via an integrated blower rated for AC 50–60 Hz to dissipate heat efficiently. Identified as Product KDA with Series 3 and Design 3 classification, the controller supports a speed command value through the high-speed SERCOS interface while omitting an auxiliary encoder input for simplified wiring. Its compact control unit also features flexible parameterization, allowing precise tuning of acceleration ramps, motor flux regulation, and safety interlocks without additional hardware.

Seamless compatibility with standard SERCOS networks and automated parameter cloning accelerate commissioning and reduce cabinet footprint. The robust blower-cooled design and overcurrent protection thresholds ensure long-term reliability even under continuous duty cycles. This spindle drive excels in high-precision machining centers, dynamic pick-and-place systems, and complex multiaxis gantry applications where performance stability and integration agility are paramount.
