Frequently Asked Questions
Purchase & Ordering
Q: Can the order numbers for 400V and 690V models be used interchangeably?
A: No, they are not interchangeable. The order number prefixes differ by voltage. Always clearly specify voltage class and grid type when placing an order.
Installation & Wiring
Q: After wiring a 690V model, it frequently shows "Overvoltage Fault" – is this a wiring error or inverter defect?
A: This is mostly due to wiring or grid issues. Check grid voltage, verify motor wiring connections, and ensure the brake resistor matches the 690V requirements.
Commissioning & Operation
Q: When commissioning with STARTER software, the safety function (STO) fails to activate – how to fix this?
A: Confirm control unit model compatibility, complete motor parameter configuration, access safety parameter group settings, and check safety circuit wiring.
Maintenance & Troubleshooting
Q: After 3 years of operation, the inverter frequently shows "Overheating Fault" – which parts need replacement?
A: Likely aging cooling fan requiring replacement. Inspect fan for noise or jamming and clean heatsink with compressed air to remove buildup.
Regional Adaptation
Q: Southeast Asian factories have high humidity – how to protect against condensation?
A: Upgrade to IP54-rated control cabinet with moisture-proof heater, seal cable entries with waterproof glands, and clean inverter interior regularly with dry air.
