INVT GD350A Empowers Textile Manufacturers to Achieve High-Precision and Energy-Efficient DTY Texturing

With the growing demand for energy saving and environmental protection in the textile industry, texturing machines are rapidly evolving toward higher efficiency and intelligence. As the core equipment for producing draw-textured yarn (DTY), texturing machines involve multiple coordinated processes such as stretching, heating, and false twisting, placing high demands on the stability and energy efficiency of the drive system.

A leading textile machinery manufacturer has replaced traditional asynchronous motors with permanent magnet synchronous motors on their texturing machines and urgently requires high-performance inverters to achieve a process upgrade.

To meet the specific process requirements of the texturing machine, the customer outlined four core priorities:
1. High-precision control: Achieve constant speed closed-loop control to ensure precise fiber curling and elasticity.
2. Environmental adaptability: Withstand high temperatures and corrosive gases generated by synthetic fiber materials.
3.  Function expansion: Support Modbus communication for seamless integration with intelligent production systems.
4.  Energy efficiency improvement: Reduce overall equipment energy consumption to meet green manufacturing standards.
