In this setting, motor begins to accelerate after dwell operation is executed for dwell time at the dwell frequency.

It is mainly used to release mechanical brake in elevators after operating at dwell frequency.

Dwell frequency : This function is used to output torque in an intended direction. It is useful in hoisting applications to get enough torque before releasing a mechanical brake. Rated Slip frequency is calculated by the formula shown below.

SV-iC5 Series specifications

LG Electronics has innovated further in the realm of HVAC solutions with its latest SV-iC5 Series. Designed to enhance energy efficiency and operational performance, the SV-iC5 Series is particularly notable for its advanced cooling and heating capabilities, making it suitable for both residential and commercial applications.

One of the standout features of the SV-iC5 Series is its use of Inverter Technology. This technology allows the system to adjust its cooling and heating output in response to real-time demands, significantly reducing energy consumption. With a higher SEER (Seasonal Energy Efficiency Ratio) rating, the SV-iC5 models are not only cost-effective but also environmentally friendly.

The SV-iC5 Series is equipped with an intelligent cooling system, which utilizes advanced sensors to monitor indoor conditions continuously. This smart adaptation ensures optimal comfort levels while maintaining efficiency. The system operates quietly, thanks to the use of advanced sound-dampening materials and design, making it an unobtrusive addition to any living or working space.

Another key technology integrated into the SV-iC5 series is the Dual Sensing Control. This feature works by simultaneously measuring both humidity and temperature to deliver precise climate control, allowing users to achieve their desired comfort levels with minimal energy use.

Additionally, the series incorporates the latest in Heat Recovery technology, enabling simultaneous cooling and heating in different zones. This versatility is particularly beneficial for larger buildings or multifamily residences, providing tailored comfort while optimizing energy use across different areas.

The SV-iC5 Series is designed with user convenience in mind. Its intuitive remote control and smartphone compatibility through the LG SmartThinQ app enable users to manage their HVAC systems with ease, whether at home or on the go.

Moreover, maintenance is simplified thanks to easy-access filters and components, ensuring that users can keep their systems running smoothly without extensive effort.

In summary, LG Electronics' SV-iC5 Series represents a significant leap forward in HVAC technology, combining energy efficiency, advanced control systems, and user-friendly features to meet the demands of modern living and working environments. With its commitment to quality and performance, LG continues to set the standard in smart HVAC solutions.
