Description
INVT GD350-19 Series VFD – Special Drive for Crane Applications.
GD350-19 is a new generation Variable Frequency Drive developed by INVT specifically for crane industry applications. It is built using advanced control technologies and years of industrial experience.
Key Features:
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.
2. Safe and reliable, no creeping
• Dedicated brake logic: Integrated torque verification ensures brake is released only after sufficient torque is built.
• High torque at low frequency: PG vector: 0Hz/200%, space vector: 0.5Hz/150% rated torque.
3. Ease of use
• Excellent load adaptability: Hoisting-specific algorithm adapts torque to varying loads.
• Crane-specific macros: One-click parameter setup for hoisting applications.
• One-click open/closed-loop switching: Fast recovery from encoder failure without runtime impact.
• Multiple control modes: Supports joystick, motorized potentiometer, remote, and communication control modes.
4. Tower crane rotation control
• Anti-eddy current control: Eliminates eddy current during rotation, enabling quick reverse braking and low-speed positioning.
• Smooth rotation control: Built-in algorithm ensures stable operation and improved efficiency.
5. Cost reduction and efficiency improvement
• 3-group motor switching: Reduces cost with time-based control. Macro parameters auto-switch even in master-slave scenarios.
6. Supports special motors
• Conical rotor motor: Flux regulation ensures fast brake control and easy debugging.
• Double-winding motor: Reliable dual-winding control.
• Outer-rotor motor: Supports non-integer gear ratios with built-in stable control algorithms.
7. High-efficiency operation
• Anti-sway function: Sensorless control suppresses swing for improved precision and efficiency.
• Light-load speed-up: Optimized speed control shortens crane cycles.
• Positioning stop: Closed-loop positioning for trolley, travel, and hoisting systems.
• Master-slave control: Ensures power balance and speed synchronization, supports flexible configurations.
Applications:
• Overhead cranes
• Hoisting equipment
• Material handling systems
• Industrial lifting machinery
