integratedflexibleindustry

GD350-19 series VFD is a new generation of VFD that INVT develops for cranes by using advanced control technologies based on more than ten-year accumulative crane-industry experience. The VFD has integrated rich lifting industry delicated control functions and STO fucntions, and can be widely applied to various cranes in different fields such as ports, factories, construction sites, and mining, with excellent control performance, comprehensive safety protection functions, and flexible expansion capability. 1. Great torque at low frequency: 0Hz/200% (of rated torque) in feedback vector control (FVC) mode; 0.5Hz/150% (of rated torque) in space voltage vector control mode 2. Excellent load adaptability: With optimized control algorithms for crane applications, the output torque can be adaptive according to the load condition so as to help achieve excellent comfortability regardless of with load or without load. 3. Tower crane slewing without vortex: Helps to implement vortex removal control, with the support for quick stop in reverse braking, quick FWD/REV switchover, and low-speed jogging positioning. 4. Conical rotor motor control: Helps adjust the magnetic flux according to the characteristics of conical rotor motor to realize fast brake release and closing control, simplify the commissioning steps, and ensure equipment safety. 5. Special-purpose braking logic: Integrates with torque verification to achieve safe run without slip after torque establishment; supports starting direction selection and brake selection in FWD/REV switchover to meet various starting requirements flexibly.
