INVT VFD series products: Leading a new chapter in industrial drive

The INVT VFD series products are a new generation of variable frequency drives carefully developed by INVT based on more than ten years of accumulated experience in the crane industry and advanced control technology. These products integrate a wealth of special control functions for the lifting industry and safe torque off (STO) functions, and can be widely used in various cranes in different fields such as ports, factories, construction sites and mining, showing excellent control performance, comprehensive safety protection functions and flexible expansion capabilities.

The power range of the INVT VFD series products is wide, covering 1.5~500kW of AC 380V (-15%)~440V (+10%) and 22~630kW of AC 520V (-15%)~690V (+10%). This enables them to meet industrial applications of different sizes and needs.

In terms of performance, the INVT VFD series has several notable features. First, they have strong low-frequency torque output capability, capable of providing 0Hz/200% (rated torque) torque in feedback vector control (FVC) mode, and 0.5Hz/150% (rated torque) torque in space voltage vector control mode. This enables the crane to operate smoothly and efficiently under various load conditions.

Second, the INVT VFD series has excellent load adaptability. Through optimized control algorithms, they can adaptively adjust the output torque according to load conditions, ensuring that the crane can provide excellent comfort when it is unloaded or loaded.

In addition, the INVT VFD series also has a variety of special functions for crane applications. For example, they support slewing eddy current-free control of tower cranes, can quickly stop reverse braking, achieve fast forward and reverse switching and low-speed fine-tuning positioning. At the same time, they can also adjust the magnetic flux according to the characteristics of conical rotor motors, achieve fast brake release and shutdown control, simplify the commissioning steps and ensure equipment safety.

In terms of safety, the INVT VFD series also performs well. They integrate a torque verification function to ensure safe and slip-free operation after the torque is established. At the same time, they also support the application of start direction selection and brake selection in forward and reverse switching to meet various start-up needs. In addition, the INVT VFD series also has functions such as upper and lower limit protection and upper and lower deceleration limit protection, which can limit the crane to operate within a specified range, ensure safety and optimize the shutdown method to improve equipment efficiency.

It is worth mentioning that the INVT VFD series also has anti-sway protection. They use a sensorless anti-sway control algorithm, which can be easily debugged and flexibly adapted to the anti-sway control needs of various cranes. In addition, they also have a loose rope protection function to avoid high-speed lifting, acceleration failures and safety accidents in a loose rope state.

In terms of energy saving and environmental protection, the INVT VFD series also performs well. They can minimize energy consumption by precisely controlling the speed and power of the motor. Compared with traditional motor drives, the INVT VFD series can automatically adjust the speed and power of the motor under different workloads, thereby achieving a higher energy efficiency ratio. At the same time, they also have less noise and vibration, and have less impact on the environment.

In general, the INVT VFD series products have become an important force in the field of industrial drives with their excellent performance, wide application fields and outstanding energy-saving and environmental protection characteristics. Whether in the crane industry or other industrial fields, the INVT VFD series products can provide users with efficient, reliable and safe drive solutions. With the continuous advancement of technology and the continuous expansion of application fields, the INVT VFD series products will surely play a more important role in the future industrial development.
