This error may occur when the voltage at the input side of the inverter drops. The RES signal is turned ON. The operation panel and inverter cannot make normal communication.
- When using a separate power source for the control circuit power (R1/L11, S1/L21) from the main circuit power (R/L1, S/L2, T/L3), this error may appear at turning ON of the main circuit. It is not a fault.
- Turn OFF the RES signal.
- Check the connection between the operation panel and the inverter.
- Check the voltage on the input side of the inverter.
