INVT GD350A: Efficient Drive Solution for Plastic Extrusion Equipment

1. All wheel drive, ensuring stable operation of plastic extrusion
The plastic extruder requires the drive system to have the characteristics of low-speed high torque and smooth operation. The INVT GD350A frequency converter with a frequency of 0.25Hz can output 150% of the rated torque, which can achieve smooth start-up and low-speed extrusion of the extruder; Its excellent speed stability (± 0.3%) can ensure uniform extrusion pressure of plastic melt and improve product quality. Simultaneously supporting magnetic flux braking, quick parking can be achieved without the need for additional brake units.

2. Flexible expansion to achieve precise control of extrusion process
The plastic extrusion process requires precise control of parameters such as temperature, pressure, and speed. The INVT GD350A is an expandable analog I/O card that can be connected to temperature and pressure sensors to achieve multi parameter closed-loop control; Through the PLC expansion card, a dedicated control program for extruders can be written to achieve collaborative control of feeding, extrusion, traction and other processes, improving the level of production automation.

3. Easy to use design, shorten equipment debugging cycle
The plastic extrusion equipment has multiple debugging parameters and complex processes. INVT GD350A comes standard with a one click self-learning function for motor parameters, which can quickly complete the parameter tuning of asynchronous and synchronous motors; Support grouping channel parameter settings, classify and manage basic parameters, motor parameters, and control parameters, making it convenient for debugging personnel to search and modify. Simultaneously supporting bilingual switching between Chinese and English to meet the usage needs of different users.

4. Energy saving and reliable, reducing production costs for enterprises
INVT GD350A adopts a new energy-saving algorithm, which can significantly reduce the operating current during the light load insulation stage of the plastic extruder, and the energy-saving effect is significant. The product is equipped with a built-in DC reactor, which can improve power factor and reduce power grid losses; At the same time, it has complete overcurrent, overvoltage, and overheating protection functions, and can operate stably in the high-temperature and dusty environment of the plastic workshop, extending the service life of the equipment.
