Product Description:

The KDA 2.1-100-3-AQD-U1 is an AC spindle drive built for delivering precise RPM control. It features advanced algorithms to maintain speed and torque stability, ensuring consistent performance in dynamic motion control processes. This drive is engineered to maintain rotational precision even under fluctuating loads, ensuring consistent motor performance. The drive uses ambient air flow to ensure efficient heat management during operation. This allows safe internal temperatures even during prolonged or high-load usage. This cooling method makes the spindle drive well-suited for standard industrial environments, ensuring long-term reliability without added system overhead.

The KDA 2.1-100-3-AQD-U1 operates on a three-phase AC input of 230/400V, enabling it to operate efficiently within typical industrial power supply ranges. The three-phase input facilitates smooth power delivery with reduced electrical noise, supporting consistent spindle performance while minimizing the risk of voltage imbalance. This drive has a 100 A current rating which enables it to deliver sufficient energy for both intense operations that involve rapid acceleration and heavy mechanical loads. This level of current handling also contributes to system reliability by ensuring that the motor receives consistent electrical input, reducing the likelihood of thermal stress or drive shutdowns in high-duty cycles.

The KDA 2.1-100-3-AQD-U1 spindle drive is designed for panel mounting, allowing it to be securely installed within electrical control cabinets. This mounting method streamlines cable management and reduces electromagnetic interference from surrounding equipment. It also simplifies system maintenance and upgrades by centralizing drive components in a dedicated location. This drive supports communication via SERCOS (Serial Real-time Communication System), enabling precise synchronization between the drive and the central control unit. This ensures that motion commands are executed with minimal latency and exact timing.
