Vector frequency converter 22 kW, 3F~3F/380V (SPLC-CV20-22G4)

General features of the 22 kW vector inverter for cranes and hoists

• Connect inverter to power supply 3ph 380 V, output to 3-phase 380 V
• Speed regulation accuracy: ±0.5% (SVC), ±0.02% (FVC)
• Built-in brake unit in all models
• Low-frequency vector algorithms

Specialised functions of the 22 kW vector inverter for cranes and hoists SPLC-CV20-22G4

• Professional torque control;
• Boundary range control function;
• Adaptive speed increase for light load;
• Intelligent anti-sway function. Built-in function prevents load swinging during transportation;
• Synchronous control function. When two hoists work simultaneously, synchronous control can align the load of each inverter, eliminate position deviations and ensure high-precision control;
• Macro function;
• Rope length determination function. Inverter can display hook height to reduce lifting-lowering speed to avoid collision with lifting drum;
• Load holding function. After stopping, the load can be held in the current position using zero-speed control;
• Overload detection function. Alarms and stops the hoisting device if the load exceeds the set upper limit;
• Maintenance reminder. Braking command count is maintained by the inverter, allowing brake maintenance planning - system check and part replacement;
• Over torque detection function;
• Motor parameter self-tuning;
• Brake malfunction detection.
