Frequently Asked Questions
Q1: Can I replace the old Yaskawa control board with a new one bought overseas directly?
Yes, just match the inverter series (GA700/CH700/E1000), plug it in directly—no debugging required, works immediately.
Q2: The IO board is plugged in but not working, what's wrong?
Usually wrong model selection (e.g., E1000 IO board can't fit GA700) or loose wiring. Recheck the model and reinsert terminals securely.
Q3: Will the boards break easily in high-temperature Middle East or humid Southeast Asia?
No, they're industrial-grade with dust-proof and moisture-proof design, suitable for harsh industrial environments.
Q4: Do these boards have CE/UL certifications for European and American markets?
Yes, all boards sold overseas have CE and UL certifications—pass customs clearance and factory inspections easily.
Q5: Is it cheaper to replace only the control/IO board instead of the whole inverter?
Definitely. It's the most common method overseas—saves significant money and time, no need to replace the entire inverter.
Q6: Different voltages in different countries—will that affect the boards?
No. Control and IO boards are control parts, not directly connected to high voltage. They're universal worldwide.
Q7: Can I add any IO expansion card to my Yaskawa inverter?
No. It must match the inverter series (e.g., SI-ES3 fits GA700, not CH700). Check the inverter model first.
Q8: Why does the board report errors after using it for a while?
Usually poor contact or dust blocking the interface. Clean the interface and reinsert it securely—this resolves most issues.
Q9: No after-sales overseas—what if the board breaks?
Just replace it with the same model. It's easy to replace yourself, no professional technician needed.
Q10: Can CH700 control boards be used for non-crane equipment?
Not recommended. CH700 is designed for cranes—its torque control is optimized for heavy-duty lifting, not general industrial use.
