Schneider Electric ATV58HU18N4

The Schneider Electric ATV58HU18N4 is a variable speed drive, also known as a variable frequency drive or VFD, designed for motor control applications. This drive is part of the Altivar 58 series and offers a range of features and operating modes that allow for precise control of motor speed and performance optimization.

Operation

The ATV58HU18N4 has two primary operating modes: Open Loop mode (SVC) and Closed Loop mode with Flux Vector Control (FVC). In Open Loop mode, there is no speed feedback from an encoder. However, speed correction can still be achieved using tacho generator feedback through an option card. In Closed Loop mode with FVC, speed feedback is provided by an incremental encoder, enabling high-performance speed and torque accuracy even at very low speeds.

Switching between these operating modes is possible through configuration parameters or assignable logic inputs. It's worth noting that the mode change takes effect only after the motor has come to a complete stop, with the speed controller locked.

Configuration and Performance

To set up the drive in Closed Loop mode with FVC, a procedure is outlined. This includes configuring motor parameters, performing an auto-tuning process to adapt the speed controller to the motor, and setting up the encoder for testing and validation.

The drive also offers performance optimization features. Manual optimization of FVC parameters involves adjusting the no-load current and nominal slip. This can be done by configuring certain parameters in the drive's menus.

Access

The drive's menus, accessed through a selector switch, provide various options for configuration and control. Different levels of access are available, depending on the operation mode and the requirements of the application. These menus allow for adjustments related to macro-configuration, motor-speed controller performance, control methods, I/O assignments, fault protection, and more.

For control inputs, the drive supports various logic input application functions, including single-action buttons, open-loop to closed-loop switching, and analog input functions. These functions allow for the customization of control inputs to suit specific application requirements.

PID (Proportional-Integral-Derivative) regulation is also available in the drive. This mode is useful for processes that require precise control based on reference and feedback signals from sensors.

Features

The drive also features a Motor Flux function (FLU), which ensures the maintenance of nominal flux in the motor during periods of inactivity, contributing to optimal starting dynamics.

Overall, the Schneider Electric ATV58HU18N4 provides a comprehensive set of features for motor control and performance optimization. Its operating modes, configuration options, and various application functions make it a versatile choice for a wide range of industrial applications that require precise speed control, efficient operation, and reliable performance.
