Product Description:
The model KDA 2.1-150-300-A00-W1 is a main spindle drive designed for high reliability in machine tool applications. It delivers accurate synchronization between drive, motor and machine through microcomputer based digital control. The compact design and efficient cooling ensure consistent performance under demanding industrial environments.
This KDA 2.1-150-300-A00-W1 Main Spindle Drive from Rexroth Indramat operates with a DC bus voltage of 300 V and supports a rated current of 150 A with a continuous current capacity of 90 A. The forced cooling with a heatsink blower maintains stable thermal conditions during heavy duty operation. The drive supports a permissible maximum ambient temperature of 55 °C under reduced data conditions and installation is feasible up to 1000 m above sea level without derating. The unit is built with a protection category of IP10. This rating offers only basic safety against accidental contact. Its digital microcomputer control ensures precise drive monitoring, diagnostic capability and fault detection. The spindle drive includes practical features that enhance operational convenience. The parameters and operating software are stored in the programming module that eliminates the need for reconfiguration when replacing units. The drive synchronizes instantly with the motor and machine once the programming module is inserted. The duplication of the programming module is simple that allows quick adaptation for similar machines or backup purposes using a duplicating adaptor or serial interface with a PC.
The KDA 2.1-150-300-A00-W1 main spindle drive provides a speed control range starting from 0.0005 rpm up to the motor’s maximum speed. This allows extremely fine control for machine tool tasks. It offers high resolution C-axis operation with precision of ≤ 1/360,000 revolution that ensures accurate positioning for machining applications.
