INVT GD350: The Ideal Drive Choice for Winding Tension Control
1. All-in-One Drive for Precise Tension Control in Winding Processes
Winding equipment imposes extremely high requirements on motor torque and speed control accuracy. The INVT GD350 has excellent torque and speed control performance, with a torque control accuracy of 5% and a torque response time <10ms, enabling precise control of tension during the winding process. It supports multiple tension control modes and roll diameter calculation methods, and features dedicated functions such as tension taper, length counting, inertia identification, and friction compensation. It perfectly adapts to various typical unwinding and winding processes including speed unwinding, torque winding, and speed winding, ensuring uniform web tension and neat winding.
2. Rich Functions with Integrated Winding-Specific Control Logic
The GD350 series has built-in rich winding industry-specific functions, enabling complex winding control without additional controllers. Its multi-function PID can be flexibly configured to meet the regulation needs of different processes. It features material break detection and pre-drive functions, which can effectively avoid problems such as material breakage and loose rolls. It supports multi-speed operation and simple PLC programming, enabling automated control of the winding process. Meanwhile, rich analog and digital interfaces facilitate connection to peripheral devices such as tension sensors and encoders.
3. Stable and Reliable Operation for Continuous Winding Production
A shutdown of a winding production line will cause a large amount of raw material waste, and the high reliability of the INVT GD350 provides a strong guarantee for continuous production line operation. The product has an instantaneous power failure ride-through function, which can continue operating using regenerative energy without shutting down when the grid voltage drops momentarily. It provides multiple braking methods including dynamic braking, DC braking, flux braking, and short-circuit braking, allowing selection of the appropriate braking scheme according to different load characteristics for fast and smooth stopping. A comprehensive fault protection mechanism can detect and handle abnormal situations in a timely manner to avoid equipment damage.
4. User-Friendly Operation for Quick Winding System Commissioning
The GD350 series optimizes the parameter setting process for winding applications, providing a dedicated tension control parameter group. Users can quickly complete system commissioning by adjusting only a few parameters according to the actual process. It supports Bluetooth wireless commissioning, allowing technicians to monitor and adjust VFD parameters from any position on the production line. The standard LCD operator panel can customize monitoring parameters to display key process data such as tension, speed, and roll diameter in real time, facilitating operators to grasp the production status at any time.
