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. Professional protection for safer operation • Travel limit protection: Integrated upper/lower limit and deceleration limit functions to restrict crane operation within a designated range, ensuring safety while optimizing stop modes and improving equipment efficiency. • Slack rope protection: Prevents accidents caused by rope slack during high-speed hoisting, malfunctions in acceleration, or rope failure. • Smooth hoisting: Automatically reduces speed when the hook lifts a load during high-speed operation, ensuring smooth hoisting and minimizing impact on the crane. • Zero servo: Locks the motor at zero speed, maintaining hold even under external force. In brake failure cases, ensures safe suspension or controlled descent. • Anti-snag protection: Emergency stop if unexpected contact occurs during hoisting. • STO (SIL2): Cuts off torque output to prevent accidental startup, allows system monitoring for quick recovery. • Braking short-circuit protection: Protects against braking resistor short circuits with ultra-high torque.
