Frequently Asked Questions
Q1: My factory uses 480VAC three-phase power - which series should I pick?
Choose the A4 series (380-460VAC) as 480V falls within its voltage range. The A2 series is only for 200-240VAC and would be damaged at higher voltages.
Q2: The inverter stops working when my conveyor has heavy loads - why?
This could be due to undersized power selection or incorrect overload time settings. Verify your model matches the motor power requirements and adjust overload parameters if needed.
Q3: Can I install two 3G3JZ inverters side by side?
Yes, but maintain at least 5cm spacing between units, especially for forced air-cooled models to ensure proper ventilation and prevent overheating.
Q4: My inverter makes a loud humming noise - is that normal?
Low hum is normal motor magnetic noise. For high-pitched whine, adjust the carrier frequency parameter (typically P012) to 5-8kHz to reduce noise levels.
Q5: I connected to Modbus but it won't communicate - what's wrong?
Verify baud rate and parity settings match (default 9600bps, 8N1), check RS485 wiring (A to A, B to B), and add 120Ω terminal resistors for long cable runs.
Q6: Can I use the AB series for a 3-phase motor?
No, the AB series outputs single-phase power only. Three-phase motors require balanced three-phase voltage to operate properly.
Q7: The inverter shows "E.OV" (overvoltage) when stopping - how to fix?
Increase deceleration time (parameter P008) or install an external brake resistor to handle motor regeneration during quick stops.
Q8: My workshop is at 1500m altitude - do I need a special model?
No special model required, but derate output current by 5% at 1500m altitude due to reduced cooling efficiency in thinner air.
Q9: Can I use this inverter for a water pump running 24/7?
Yes, the 3G3JZ is rated for continuous duty. Ensure proper sizing and enable pump mode (parameter P020) to prevent water hammer.
Q10: The display is in Japanese - how do I change to English?
Hold MODE key for 3 seconds, navigate to language settings (usually around P050), and select English. Consult the user manual for detailed instructions.
