Common Questions & Solutions
Q: The GA700 triggers EMC warnings during testing. What's wrong?
A: Check if your model has the "BBA" suffix (built-in EMC filter). Ensure proper wiring separation between power and control cables (≥10cm apart) and verify adequate ground wire thickness and connection.
Q: Inverter shuts down with "OV" (overvoltage) error in areas with voltage fluctuations.
A: Adjust "Voltage Fluctuation Tolerance" to 15% in parameters. For frequent deceleration applications, use built-in brake transistor with external brake resistor to dissipate regenerative voltage.
Q: Can GA700 work with existing Profinet systems?
A: Yes, select "Profinet option" when ordering. Ensure PLC baud rate matches (100Mbps) and enable "Profinet Communication" in parameter Pn001 during commissioning.
Q: Keypad malfunctions in humid environments.
A: Replace standard keypad with optional IP54 waterproof keypad or install inverter in sealed electrical cabinet with dehumidifier.
Q: Energy savings potential for fan systems?
A: Automatic energy-saving mode adjusts motor speed according to air pressure, typically saving 25-40% energy compared to power-frequency operation.
