Specialised Functions of the 45 kW Vector Converter for Cranes and Hoists SPLC-CV20-45G4

• Professional torque control;
• Limit travel control function;
• Adaptive light load speed increase function;
• Intelligent Swing Prevention Function. Built-in function prevents cargo shaking and swinging during movement;
• Synchronous Control Function. When two hoists operate simultaneously, synchronous control can balance the load of each converter, eliminate position deviations, and ensure precise control;
• Macro function;
• Rope Length Detection Function. The converter can display the hook height, allowing for reduced lift descent speed to avoid collision with the lifting drum;
• Load Holding Function. After stopping, the load can be held in position by control at zero speed;
• Overload Detection Function. Displays a warning and stops the lifting device if load exceeds the set upper limit;
• Maintenance Reminder. The brake command count is recorded by the converter, allowing planning for brake system maintenance and parts replacement;
• Excessive torque detection function;
• Automatic motor parameter tuning;
• Brake fault detection.
