General Features of 250 kW Vector Converter for Cranes and Lifts

• Connection of the inverter to the power supply network 3Ph 380 V, and output — motor at 3-phase 380 V
• Speed regulation accuracy: ±0.5% (SVC), ±0.02% (FVC)
• Integrated braking block in all models
• Low-frequency vector algorithms

Specialised Functions of 250 kW Vector Converter for Cranes and Lifts SPLC-CV20-250G4

• Professional torque control;
• Limit control function;
• Adaptive speed increase for light loads;
• Intelligent anti-sway function. Built-in feature to avoid shaking and swaying of loads during movement;
• Synchronous control function. When two lifts operate simultaneously, synchronous control can level the load on each inverter, eliminate position deviations and ensure high-precision control;
• Macro function;
• Cable length detection function. The inverter can display the hook height to reduce lifting-lowering speed to avoid collision with the lifting drum;
• Load holding function. After stopping, the load can be held in the current position through zero-speed control;
• Overload detection function. Displays alarm and stops lifting device if load exceeds defined upper limit;
• Maintenance reminder. The inverter counts the number of braking commands, allowing planning of brake system maintenance - checking and replacing parts;
• Over-torque detection function;
• Self-tuning of motor parameters;
• Brake failure detection.
