The Bosch Rexroth Indramat KDA 3.2-150-3-L00-U1 from the KDA Spindle Drives series merges the rugged reliability of the Product KDA platform with the proven architecture of Series 3 and Design 2. This drive controller supports a Current Rated of 150 A alongside a Continuous Current rating of 90 A, ensuring substantial torque reserves for high-dynamic machining applications. Rated for a DC Bus Voltage of 300 V, it accommodates demanding spindle loads while maintaining precise speed regulation. Native integration of a SERCOS interface speed command value underscores its compatibility with modern CNC and automation networks.
Cooling and durability are engineered into every element: forced cooling is achieved via a dedicated heatsink blower fed by an AC 50–60 V blower connection voltage, guaranteeing consistent thermal management under extended high-load conditions. The absence of an auxiliary interface on the Aux. Encoder Input simplifies the design for systems leveraging external encoder modules. High-voltage isolation and transient suppression protect the controller electronics, while sturdy mechanical mounting features ensure minimal resonance and high stiffness when installed on milling and turning spindles.
Installation and commissioning are streamlined through clear terminal designations, compact dimensions, and an intuitive SERCOS protocol that supports real-time speed and position control. With its combination of a 300 V DC link, 150 A peak current capability, and proven Bosch Rexroth Indramat heritage, the KDA 3.2-150-3-L00-U1 drive controller represents an optimal solution for advanced machine tool spindle drives requiring high power density, precise speed regulation, and reliable long-term operation.
