INVT GD330-450G/500P-4 frequency converter

INVT GD330 frequency converter is the safe and reliable choice for the lifting industry

1. High torque starting ability to easily cope with heavy load conditions
The lifting equipment needs to be started and operated under heavy loads, which places high demands on the starting torque capability of the frequency converter. The INVT GD330 series frequency converter can provide a starting capacity of 150% of the rated torque, ensuring that lifting equipment can start smoothly even under full load conditions. At the same time, GD330 has excellent low-speed torque characteristics, which can output stable torque at low speeds and achieve precise position control. GD330 can provide reliable driving support in the lifting, slewing, large and small mechanisms of cranes.

2. Zero speed hovering function ensures safe operation
The safety of lifting operations is crucial, and zero speed hovering function is one of the core functions of lifting frequency converters. The INVT GD330 series frequency converter has strong zero speed torque holding capability, which can output sufficient torque when the motor stops rotating, preventing heavy objects from slipping. At the same time, GD330 adopts reliable brake timing control to ensure that the opening and closing of the brake are perfectly coordinated with the operation status of the motor, avoiding the occurrence of hook slipping. These functions greatly improve the safety of lifting operations and protect the safety of personnel and equipment.

3. Anti shake control technology improves work efficiency
During the operation of a crane, the swinging of heavy objects can affect operational efficiency and safety. The INVT GD330 series frequency converter integrates advanced anti roll control technology, which can effectively suppress the swinging of heavy objects by optimizing acceleration and deceleration curves and torque control. Anti sway control technology can significantly shorten the operating cycle of cranes, improve operational efficiency, reduce collision accidents caused by heavy object swinging, and enhance operational safety.

4. Comprehensive security protection ensures reliable operation of equipment
The safe operation of lifting equipment is related to the safety of personnel and property. The INVT GD330 series frequency converter is equipped with comprehensive safety protection functions. The product has various conventional protection functions such as overcurrent, overvoltage, undervoltage, overheating, overload, short circuit, etc. It also specifically adds functions such as over torque protection, overspeed protection, and limit protection for lifting applications. Meanwhile, GD330 supports STO (Safe Torque Cut off) function, which can quickly cut off motor torque in emergency situations to ensure equipment safety.
