KDA 2.1-50-300-A00-W1/115V

KDA 2.1-50-300-A00-W1/115V, Bosch Rexroth Indramat, KDA Spindle Drives delivers a robust main spindle drive solution designed for high-precision machining environments. The unit features standardized electrical connections and must be grounded directly to the associated supply module per manufacturer’s schematic. Its integrated heatsink blower ensures continuous operation under demanding conditions, while the absence of an auxiliary encoder input simplifies installation and reduces wiring complexity. Built around the proven KDA platform, this drive marries decades of spindle control expertise with modern cooling technology.

Engineered for seamless integration, the drive accepts a 300 V DC bus voltage across two DC bus terminals and draws up to 50 A current rating via a dedicated KDV compatible power supply. Forced cooling style from the onboard heatsink blower maintains optimal thermal performance, even in extended cycles. Constructed to Design Code 1 and Series Code 2 standards, the module embodies the Family KDA heritage of reliability and serviceability. Vertical mounting orientation is mandatory to ensure proper airflow through the heat exchanger, and the aluminum heatsink pushes securely into cutouts above the blower, fastened by precision-fitting bolts. A built-in Programming Module: Yes slot on the top right hosts configuration data and retains all parameters and operating software for quick field replacement.

Designed for durable operation, the spindle drive’s high stiffness mechanical interface and M1-KD accessory kit deliver secure mounting within the control cabinet and, when paired with a shock-absorbing base, withstand transport-induced vibration. The flat gasket on the module top ensures a reliable seal against dust and contaminants, while the plug-in three-pin terminal and 16-pin bus strip simplify signal routing. Engineers benefit from plug-and-play parameter cloning and elimination of tedious resets during replacements. Ideal for machine-tool builders and retrofit projects, the KDA 2.1-50-300-A00-W1/115V drive offers unparalleled integration, maintenance efficiency, and long-term operational reliability.
