As the textile industry undergoes transformation, upgrading, and accelerated intelligent retrofitting, sizing machines face increasing demands for low energy consumption, high efficiency, and quality. INVT's sizing machine control system helps customers save energy and improve efficiency.
High equipment energy consumption leads to significant electricity cost pressure and fails to meet green production requirements.
Large yarn tension fluctuations and poor winding results affect weaving efficiency and fabric quality.
Slow response of individual control units limits production line speed and output capacity.
Limited electrical cabinet space and complex multi‑axis wiring make maintenance difficult.
The VS‑Q HMI, TM series PLC, and GD600 multi‑drive inverters are used, networked via EtherCAT‑to‑CANopen bus. Each unit motor operates with closed‑loop control; PID tension control is applied to the yarn in the dry section, and winding maintains constant tension. The GD600 shared DC bus saves cabinet space and enables energy‑saving regenerative feedback.

Multi‑drive shared DC bus + dry‑section PID tension control helps sizing machines save energy and improve quality.
Technical Claims
1. High‑Speed Bus: EtherCAT‑to‑CANopen provides a simple system structure with fast response.
2. Shared DC Bus: The GD600 multi‑drive allows energy from regenerative axes to be used by motoring axes, achieving over 20% energy savings.
3. Dry‑Section PID: PID tension control for yarn in the dry section ensures stable tension across different speeds.
Roving Frame
The roving sub-industry is accelerating transformation and upgrading. INVT launches the full electric control system for roving frames, helping customers improve product quality and production efficiency.
Spinning Frame
Ring spinning frames are undergoing a profound transformation from "manufacturing" to "intelligent manufacturing." INVT has launched an all-electric control system for ring spinning frames, enabling rapid process adjustment and real-time monitoring functions, reducing manual intervention, and enhancing production flexibility.
Rotor Spinning Machine
Integrates INVT's complete control solution, achieving the breakthrough of INVT's full solution's first application in the rotor spinning industry. The AX70 medium-sized PLC is used to enhance control performance, stabilize control algorithms, and improve the user experience.
Loom Main Motor Direct Drive
The international economic environment in the textile industry is becoming increasingly challenging, placing higher demands on production costs for domestic weaving enterprises. INVT's loom main motor direct drive solution can significantly reduce energy consumption in loom production, aligning with "carbon neutrality" goals.
Jacquard Head Direct Drive
To meet the market demand for jacquard fabrics, INVT provides the DA200 series high-performance AC servo direct drive system for electronic jacquard heads. This solution addresses issues associated with traditional line-shaft transmission mechanisms, such as low speed, poor efficiency, high noise, and high maintenance, and has been well-received by customers.
Beaming Machine
A beaming machine consists of a creel and a headstock. It requires a tension control device to automatically maintain constant and uniform let-off tension for warp yarns from each beam, while the winding mechanism of the headstock winds the warp yarns at a constant speed. INVT provides an HMI + AX70 + GD600 control solution based on the on-site process requirements of the beaming machine.
Texturing Machine
To meet market demands for increased speed and efficiency in texturing machines, INVT provides a complete control system for high-speed texturing machines. This solution simplifies the mechanical transmission structure and utilizes high-performance vector technology to achieve stable high-speed motor control, helping customers reduce costs and increase efficiency.
Oval Printing Machine
The control system is built using an AX70 controller with multiple remote expansion modules. The EtherCAT bus controls all servo systems. The two main spindles are synchronized using electronic gearing, and each station has an independent remote I/O module. Customized cloud services are supported, enabling remote functions such as machine locking, program download, and control commands.
Spreading Machine
The apparel industry is labor-intensive. As labor costs rise and consumer demands for garment comfort increase, INVT's spreading machine control system enhances the level of automation and spreading quality, helping customers reduce costs and improve efficiency.
Synthetic Fiber Post‑Spinning Line
Imported inverter brands have long held a dominant position in the chemical fiber industry. INVT's GD880 engineered drive inverter solution enables customers to break free from this import dependency and reduce costs.
Automatic Towel Cross‑Sewing Machine
INVT's control system for automatic towel cross‑sewing machines enhances equipment stability and increases product competitiveness for customers.
High‑Temperature Airflow Overflow Dyeing Machine
High‑temperature airflow overflow dyeing machines operate in hot, humid environments where electrical equipment is prone to damage, affecting operational stability. INVT's high‑protection inverter solution addresses this issue, improving equipment stability and reducing maintenance costs.
