Product Description:

The KDA 3.2-050-3-LQS-W1 is a multi-purpose spindle motor with user-adjustable parameters. It provides enhanced motion control over a broad speed range, supporting high-performance motors in diverse applications. Its user-adjustable parameters enable adaptable drive behavior allowing the drive to be integrated into systems with varied operational demands. This ensures process-specific control and dynamic responsiveness based on real-time application needs. The drive ensures consistent spindle motor performance by relying on integrated digital servo control to deliver tight motion profiles. This control type processes high-resolution input signals in real time and then modifies motor commands accordingly, for more precise and repeatable motion.

Designed for dynamic motion applications, the DA 3.2-050-3-LQS-W1 can provide steady power under typical operating conditions and handle brief spikes in demand. In continuous load scenarios, like extended machining or production cycles, the nominal 50 A rating provides steady and effective drive performance. Under peak loads, the drive can temporarily supply up to 63 A to effectively handle elevated power demands during dynamic load transitions. This drive supports flexible input within a 380 to 480 V AC range. This allows it to integrate easily into varied system setups and operate effectively even when power supply is consistent or prone to minor fluctuations.

The KDA 3.2-050-3-LQS-W1 has a total weight of 14 kg, providing a build of moderate weight that allows for easier handling during installation. The drive is equipped with multiple connectivity options, enabling versatile system integration into both modern and legacy systems. It comes with a SERCOS fiber optic interface for high-speed data exchange between components and digital I/O channels allow for signal handling. The drive operates reliably even in challenging environments due to sturdy construction but installation in enclosed panels is recommended to prevent exposure to contaminants.
