Product Description:
The KDA 2.1-100-3-DPI-U1 Spindle Drive is designed by Bosch to provide stable output in industrial automation. It provides accurate drive control for spindle systems across multiple applications.
The KDA 2.1-100-3-DPI-U1 drive belongs to the 2 series. This classification places it within a defined range of drives that are designed for accurate spindle regulation. The design is marked as type 1. The rated current is 100 A. This allows the drive to handle high dynamic load conditions without affecting its stability. The continuous current is 70 A. This current confirms the ability of the spindle drive to provide prolonged operation under steady mechanical demand. The speed command value is provided in a digital 16-bit parallel format. The high resolution guarantees correct speed references and supports precise positioning of the spindle. An auxiliary encoder input is included for spindle or secondary motor feedback. An incremental encoder output is also available. This allows external monitoring systems to align with motor shaft movement. The mounting system uses a mechanical kit designated M1-KD. This standardized assembly makes installation easy within equipment racks. The weight of the mechanical mounting kit is 1.7 kg.
The KDA 2.1-100-3-DPI-U1 drive has a DC bus voltage of 300 V. This voltage support allows effective transfer of energy within multi-axis installations. The drive is forced-cooled by using a heatsink blower. Active airflow control prevents thermal overload and stabilizes continuous operation. The AC supply source for the blower is 115 V. This input ensures reliable working of the fan independent of motor load. Low accessory mass reduces additional stress on structural supports. The blower unit itself has a weight of 4.2 kg.
