Cause : Parameter write error comes when parameter copy from the operation panel to the inverter was attempted during operation.
- A failure has occurred at the operation panel side EEPROM while writing the copied parameters.
- A failure has occurred in the USB memory device while writing the copied parameters or PLC function project data.
- Check that the inverter is stopped.
- After stopping the operation, perform parameter copy again.
- The operation panel (FR-DU08) may be faulty.
- Perform parameter copy or PLC project data copy again.
- The USB memory device may be faulty. Replace the USB memory device.
