Product Description:
The Bosch Rexroth Indramat KDA 3.2-050-3-DY0-W1 belongs to the KDA Spindle Drives series and is used as a spindle drive for high-speed spindles in CNC machining centers. Positioned between the controller and the motor, it converts DC-link energy into controlled three-phase output while processing feedback to maintain commanded speed and torque. This operating role supports cutting, drilling, and grinding processes that depend on stable spindle behavior for dimensional consistency, repeatable tool response, and reliable surface finish quality.
The power section operates from a DC bus of 300 VDC, and the inverter can supply a continuous phase current of 50 A to the connected spindle motor during sustained operation. A dedicated heatsink blower is powered by 220 V/50–60 Hz, so cooling can remain active even when the DC bus is discharged. Internal temperature control relies on forced-air cooling, which helps keep the power semiconductors within safe limits during extended high-load cycles. Speed information is accepted through a 16-bit parallel digital command channel, allowing the CNC to send setpoints directly without digital-to-analog conversion delays and with full resolution across the usable speed range.
The permitted ambient operating range is 5 to 45 °C, which supports use in normal shop-floor conditions when airflow around the unit is maintained. Installations are allowed up to 1000 m above sea level without additional derating. For applications that require coordinated feedback functions, the drive includes a second encoder input and synchronous input, which can be used for spindle orientation or master-slave operation with precise phase alignment. This arrangement allows the control system to coordinate spindle position and timing functions without adding a separate feedback module.
