Product Description:
The KDA 2.1-150-3-AQI-W1 Spindle Drive is designed with a rated current of 150 A, providing stable electrical performance in spindle applications. Bosch Rexroth Indramat manufactures this spindle drive.
The KDA 2.1-150-3-AQI-W1 drive works with a DC bus voltage of 300 V, providing a consistent energy supply during production cycles and dynamic loads. Its installation involves vertical mounting, with grounding bolts located at the top, to provide safe operation, grounding, and mechanical support during use. The weight of its mechanical mounting accessory is 1.7 kg, enabling easy handling and mounting with retained structural stiffness for accurate system integration. This spindle drive follows electrical protection class IP10 per DIN 40050 with protection against accidental contact with solid objects in controlled environments. It accommodates a peak ambient operating temperature of +55 °C and enables reliable operation in industrial environments where higher thermal conditions exist. This spindle drive employs forced cooling using a heatsink blower, with efficient thermal control and guarantees reliable operation in extended or intensive spindle use. This heatsink blower demands an AC power supply of 220V at 50–60 Hz, which is compatible with most industrial electrical setups.
This drive uses analog ±10V speed command values to enable precise control and spindle speed regulation with high accuracy in different automation processes with consistent motion precision. This drive includes an auxiliary encoder input for 1V sinusoidal encoders to facilitate highly accurate spindle feedback and smooth control during high-performance operation. It has an incremental encoder output as an auxiliary interface to offer precise feedback monitoring and eliminates integration barriers with external controller systems. The KDA 2.1-150-3-AQI-W1 drive uses an X2 37-pin connector interface for connection, facilitating dependable communication and standardized integration with numerical control systems.
