KDA 3.1-100-3-AYD-U1
KDA Spindle Drives
The KDA 3.1-100-3-AYD-U1, Bosch Rexroth Indramat, KDA Spindle Drives model is a robust digital spindle amplifier designed for precision industrial automation. It delivers a continuous current of 100 A to compatible MAC servo motors, ensuring stable torque under dynamic load. The drive accepts a three-phase 380-480 V AC power input at 50/60 Hz and integrates seamlessly into standard control cabinets with its panel-mount form factor. Air-cooled operation maintains internal temperatures without the need for auxiliary liquid cooling systems.
Designed for demanding spindle applications, this unit features a Digital servo amplifier control type and a proprietary Bosch Rexroth Indramat communication interface for high-speed data exchange. It supports a DC Bus Voltage of 300 V and an analog Speed Command Value of ±10 V, while providing an Aux. Encoder Input with auxiliary and synchronous signals. The drive’s three-axis capability, protection class IP10, and panel-mount architecture simplify multi-spindle installations and cabinet layouts. Rated for an ambient operating temperature of 0 to 45°C, it weighs approximately 35 kg, balancing rigidity and compactness for mid-range racks.
Engineers benefit from fast digital feedback loops and a modular mounting system that streamlines maintenance and hot-swap replacements. The combination of robust air cooling, precise current control, and a dedicated communication interface enhances reliability in continuous-duty environments. Ideal for high-speed spindles, machining centers, and dynamic automation cells, the KDA 3.1-100-3-AYD-U1 drive delivers consistent performance and simplified integration under varied factory conditions.
