Product Description:
The KDA 3.2-050-3-A00-U1 is a Bosch Rexroth Indramat module in the KDA Spindle Drives series. It converts a constant DC link into a controllable three-phase output that governs high-speed spindle motors used in CNC machining and grinding equipment. By integrating power electronics with an onboard cooling assembly, the drive stabilizes torque during rapid acceleration and deceleration, helping production cells maintain consistent surface finishes and cycle times. This type of control is suited to spindle applications that require quick speed changes without unstable motor response.
The power stage is energized by a DC bus rated at 300 VDC, while its continuous output ceiling of 50 A gives connected spindles a wide operating range before current limiting occurs. Thermal energy leaves the drive through a mounted heat sink blower that receives its own supply of 115 V at 50/60 Hz, so airflow is available even when the main converter is idle. Command information reaches the control board as an analog speed reference, enabling smooth speed ramps set by the machine controller. The separate blower supply keeps cooling independent of the main power stage. This model is in design series 3 and version 2, and its forced-cooling layout helps keep semiconductor temperature under control during extended high-load operation.
The permissible workspace temperature spans 5 to 45 °C, and mounting height must remain under 1000 m above sea level so the blower can deliver its intended airflow. Feedback wiring is straightforward because the unit has no additional input for a second encoder. Expansion slots are absent because there is no additional interface option, so all motion commands and diagnostic signals pass through the standard terminal set. This arrangement leaves the external connections focused on the core control and monitoring functions used by the drive.
