Product Description:
The KDA 3.1-150-3-AQI-W1 spindle drive is manufactured by Bosch Rexroth Indramat within the KDA Spindle Drives series. The unit converts a regulated DC link into three-phase power for high-speed machine tool spindles and processes external speed commands from CNC platforms. Integrated Series 3 control electronics supervise current, voltage, and temperature so the drive can maintain precise acceleration and braking profiles for cutting, drilling, and grinding equipment. This makes it suitable for spindle applications that require steady speed control during machining and rapid response when load conditions change. Its compact rack format suits control cabinets where the spindle drive operates alongside other motion modules.
Electrically, the drive can deliver a continuous output of 150 A, providing ample spindle torque across the full speed range. It is energized by a shared bus at 300 VDC, so the power distribution must match that input level. Acceptable ambient conditions span 5 to 45 °C, and operation is permitted up to 1000 m above sea level without derating. Speed regulation is achieved through an analog reference, typically ±10 V, which the internal control board filters and scales before modulating the inverter. Stable handling of the command signal helps the spindle reach target speed smoothly and respond predictably to programmed changes in setpoint.
Thermal energy is removed by a heat sink blower powered from a dedicated 220 V/50-60 Hz supply. The active cooling hardware comprises a mounted heat sink blower that operates in forced cooling mode, keeping internal temperatures controlled during long production shifts. For position and speed feedback, the drive offers an incremental encoder output that can be wired directly to higher-level motion controllers. This arrangement provides real-time spindle feedback during ramp-up, steady running, and deceleration without requiring a separate feedback conversion stage in the cabinet.
