VC3200 special inverter for injection molding machine is a kind of inverter used for injection molding machine. It can adjust the pressure and flow of the injection molding machine to achieve energy saving purposes, and has protection functions. It adopts sensorless vector control, automatic identification of motor parameters, and operates quietly.
The VC3200 series frequency transformer provides variable‑speed control for the oil‑pump motor of injection molding machines, enabling energy‑saving operation and continuous production even if the inverter fails. It features sensor‑less vector control, automatic motor parameter identification, low harmonic current output, and comprehensive protection functions.
The document covers model specifications, physical dimensions, main‑circuit and control‑circuit wiring, pressure and flow input terminals, function‑code parameters, and safety‑critical installation and debugging procedures. This manual is written in Chinese.
| Input power supply | 3Φ 380V 50/60Hz |
|---|---|
| Output power rating | 55 kW |
| Maximum output current | 110 A |
| Rated output current for 55 kW model | 110 A |
| Rated output current for 30 kW model | 60 A |
It allows the injection machine to keep running even if the frequency transformer fails.
The start circuit must be connected after the oil‑pump motor completes the Y‑Δ conversion; otherwise the inverter may be damaged.
It provides over‑voltage, under‑voltage, over‑current, current limiting, overload, over‑temperature, electronic overload relay, over‑voltage stall, data protection and automatic fault reset.
