Product Description:
The KDA 3.2-100-3-AQ0-W1 is a spindle drive manufactured by Bosch Rexroth Indramat for the KDA Spindle Drives series. In machine-tool automation, it converts regulated DC-bus energy into variable three-phase power so that high-speed motors can maintain precise speed control during cutting, boring, or grinding cycles. The unit belongs to series 3 and operates as a standalone axis module that relies on an internal heatsink blower rather than cabinet ventilation. This layout suits machines that use a dedicated spindle channel and need stable speed response as cutting load changes.
The heatsink blower is powered from an auxiliary source rated at 220 V/50–60 Hz, letting the cooling circuit stay active even when the DC link is de-energized. Main power reaches the drive on a shared bus that supplies 300 VDC, which matches the characteristic voltage used by compatible Indramat supply modules in multi-axis racks. Thermal removal is handled by a mounted heatsink blower working in forced cooling mode, so airflow remains stable under changing spindle loads. The power stage can deliver a continuous phase current of 100 A, allowing the drive to run medium-frame asynchronous or synchronous spindles without derating. Because the speed reference is processed as an analog signal, the command loop can integrate with legacy CNC controls through differential voltage channels. This arrangement helps the drive maintain thermal stability during long machining cycles.
Ambient operation is permitted from 5 to 45 °C, and installation is allowed up to 1000 m above sea level. The speed command uses an analog interface, which supports systems that do not use fieldbus communication. It can therefore fit control architectures that use conventional analog speed commands and only need the base drive functions. The unit has no additional interface option, so it relies on its standard control connections. The control board is Series version 2, indicating an updated signal-conditioning revision compared with earlier releases.
