Vector frequency converter 55 kW, 3F~3F/380V (SPLC-CV20-55G4)

General features of the 55 kW vector frequency converter for cranes and hoists

• Connecting the frequency converter to the power grid 3ph 380 V, and output — motor at 3 phase 380 V
• Speed regulation accuracy: ±0.5% (SVC), ±0.02% (FVC)
• Built-in braking unit in all models
• Low frequency vector algorithms

Specialised functions of the 55 kW vector frequency converter for cranes and hoists SPLC-CV20-55G4

• Professional torque control;
• Travel limit control function;
• Adaptive speed increase for light load;
• Intelligent anti-sway function. The built-in function avoids shaking and swaying of the load during movement;
• Synchronous control function. When two hoists operate simultaneously, the synchronous control aligns the load of each frequency converter, removes position deviation and ensures high-precision control;
• Macro function;
• Rope length detection function. The frequency converter can display the height of the hook to reduce the lifting-lowering speed to avoid collision with the hoisting drum;
• Load holding function. After stopping, the load can be kept in position by zero-speed control;
• Overload detection function. Displays an alert and stops the lifting device if the load exceeds the preset upper limit;
• Maintenance reminder. The number of braking commands is counted by the frequency converter, allowing planning of brake maintenance - checking the system and replacing parts;
• Torque overrun detection function;
• Self-tuning of motor parameters;
• Brake failure detection.
