INVT GD350: High-Performance VFD Dedicated to Hoisting Machinery

1. All-in-One Drive Meets Complex Working Conditions of Hoisting Machinery

Hoisting machinery has complex operating conditions and imposes extremely high requirements on VFD torque control and overload capacity. The INVT GD350 has excellent torque control performance, delivering 200% rated torque at 0Hz, ensuring smooth starting of cranes under heavy load conditions. With a torque response time <10ms, it can quickly respond to load changes and prevent load slipping. It supports multiple braking methods for fast and smooth stopping, ensuring safe and reliable hoisting operations.

2. Rich Functions with Integrated Hoisting-Specific Control Logic

The GD350 series has built-in rich hoisting industry-specific functions, enabling complete crane control without additional controllers. It supports dedicated functions such as multi-speed operation, torque limiting, anti-slipping, and light-load high-speed, perfectly adapting to various types of hoisting equipment including bridge cranes, gantry cranes, and tower cranes. Meanwhile, rich expansion interfaces facilitate connection to safety devices such as load limiters and limit switches, further enhancing the safety of hoisting operations.

3. Safe and Reliable Design for Personnel and Equipment Protection

Safety is the top priority in hoisting operations, and the INVT GD350 comes standard with a SIL 2 certified Safe Torque Off (STO) function, which can quickly cut off motor torque in emergency situations to prevent accidents. The product has comprehensive fault protection functions, including overcurrent, overvoltage, undervoltage, overtemperature, phase loss, and overload protection (more than 30 types in total), which can detect and handle abnormal situations in a timely manner. Additionally, the product has passed strict vibration and shock tests, adapting to the harsh operating environment of hoisting machinery.

4. Convenient Operation to Simplify Hoisting Equipment Commissioning and Maintenance

The GD350 series optimizes the parameter setting process for hoisting applications, providing a dedicated hoisting parameter group. Users can quickly complete system commissioning by adjusting only a few parameters according to actual working conditions. It supports Bluetooth wireless commissioning, allowing technicians to complete parameter setting and status monitoring without climbing the crane. The standard LCD operator panel can display key data such as lifting weight, operating speed, and lifting height in real time, facilitating operators to grasp the operation status at any time.
