Product Description:
Model number KDA 2.1-050-3-APS-U1 emerges from Indramat’s KDA Spindle Drives product series, presenting a rated current of 50 A which sustains high‑torque spindle loads. A three‑axis capability grants simultaneous control over multiple spindles which broadens machining flexibility. The presence of an air‑cooled mechanism expels unnecessary heat without fluid circuits just to streamline maintenance workflows.
This three‑phase and 230/400 V AC input voltage is suitable for common industrial grids which minimizes power‑conversion hardware. Dual‑frequency operation is rated at 50/60 Hertz enables deployment in diverse regions to reduce setup complexity. APS power supply integration houses drive electronics together which shrinks cabinet footprint. An IP20 protection class prevents intrusion of solid objects bigger than 12 mm which safeguards internal electrical components. The product delivers an analog ±10 V speed command input, enabling direct control references and streamlining response adjustments. With this 115 VAC AC-powered blower cools the heatsink, ensuring efficient thermal regulation and stable operation. An auxiliary input for encoder designed for a spindle or secondary motor and tracks real time position data enhancing feedback accuracy and boosting synchronization across the axis. A serial RS‑232 C auxiliary interface enables straightforward diagnostics which accelerates commissioning.
An approximate weight of 24 kg for Indramat’s KDA 2.1-050-3-APS-U1 balances robust construction with manageable handling, easing installation efforts. Control‑cabinet mounting secures the device within enclosed systems to further reduce vibration exposure. Employing bus voltage value of 300 V DC ensures a steady connector supply, effectively minimizing current ripple amid frequent load variations. The digital control architecture for this variant delivers precise command processing which enhances velocity and position regulation. A standard bus connection interface links the drive to higher‑level controllers which simplifies network integration. Cabinet‑mount dimensions of 390 × 450 × 230 mm fit into standard racks which maximizes panel density.
