Product Description:
The Bosch Rexroth range of high-performance three-phase drives includes the compact KDA 2.1-100-3-AQI-W1 model. This unit offers exceptional regulation of speed and torque in spindle applications. It delivers enhanced stiffness ensuring responsive performance under varying load conditions. This drive is designed to operate as part of a modular drive system, contributing to improved axis control and consistent spindle behavior, even during rapid changes in direction or speed. Its robust control capabilities make it a dependable option in motion control applications that require fine-grained control for optimal productivity.
For reliability in prolonged use, the KDA 2.1-100-3-AQI-W1 incorporates a forced cooling system that is powered by an integrated heatsink blower. As the unit drives heavy spindle loads, the blower directs concentrated airflow across heat-dense components, quickly removing excess heat from the system. This prevents thermal derating and allows the drive to deliver consistent performance under varying loads and speed conditions. This drive is suited for signal inputs in the ±10V range, facilitating seamless integration into both new and existing machine architectures. The drive can supply a substantial and stable output to spindle motors with its high current capacity of 100 A. This high power handling capability helps prevent performance drops under peak load. This makes the drive suitable for medium- to high-power spindle applications.
This drive comes with an auxiliary interface for incremental encoder output. This interface allows the controller to monitor and adjust motor behavior dynamically, enhancing synchronization and accuracy in spindle positioning. The auxiliary incremental encoder output also enables improved diagnostics and system tuning, contributing to greater process reliability and tighter control. The drive has environmental protection to safeguard against damage from debris and other contaminants per IP20 guidelines.
