DANGER

HAZARD OF ELECTRIC SHOCK OR ARC FLASH

During auto-tuning, the motor operates at rated current.

Do not service the motor during auto-tuning.

Failure to follow these instructions will result in death or serious injury.

DANGER

UNINTENDED EQUIPMENT OPERATION

The Nominal Motor Parameters UnS, FrS, nCr, nSP, nPr and COS must be correctly configured before starting auto-tuning.

If one or more of these parameters is modified after auto-tuning has been performed, tUn will return to nO￿and the procedure must be repeated.

Failure to follow these instructions will result in death or serious injury.

ATV312 specifications

Schneider Electric's ATV312 is a versatile series of variable speed drives (VSD) designed to optimize the performance of a wide array of motor applications. Known for its robust construction and advanced technology, the ATV312 is particularly suited for use in various sectors including HVAC, water treatment, and industrial automation.

One of the key features of the ATV312 is its ability to control a three-phase asynchronous motor's speed and torque precisely. The drive supports both open and closed-loop control modes, making it adaptable to different operational requirements. With power ratings ranging from 0.75 kW to 15 kW, it provides a broad spectrum of applications.

The drive incorporates a state-of-the-art digital signal processing (DSP) technology that enables real-time performance monitoring and control. This technology allows for enhanced dynamic response, reducing energy consumption while maximizing the efficiency of the connected motors. It features built-in energy-saving functions that automatically adjust the operating parameters based on load conditions, helping to significantly lower energy costs.

The ATV312 is equipped with an intuitive human-machine interface (HMI) that simplifies programming and operation. The drive offers multiple communication options such as Modbus, CANopen, and Ethernet, allowing for seamless integration into existing control systems and easy monitoring. Additionally, the ATV312 supports multiple control modes including scalar control and vector control, providing flexibility to meet diverse application needs.

Safety is a priority with Schneider Electric, and the ATV312 doesn't fall short. It features an integrated safe torque off (STO) function, enhancing operational safety by allowing for immediate deactivation of motor torque. This drive also complies with global standards such as CE, UL, and RoHS, ensuring reliability and safety.

Another notable characteristic of the ATV312 is its compact design, which facilitates easy installation in tight spaces. Furthermore, it operates in a wide temperature range, allowing it to function effectively in various environmental conditions. When it comes to maintenance, the ATV312 is designed for long life, with built-in diagnostics that help in timely identification of potential issues, thereby minimizing downtime.

Overall, Schneider Electric's ATV312 embodies advanced drive technologies, robust features, and user-friendly characteristics, making it an ideal choice for operators seeking to enhance the efficiency and reliability of their motor-driven applications.
