Error
The RES signal is turned ON.
The operation panel and inverter cannot make normal communication (contact faults of the
connector).
This error may occur when the voltage at the input side of the inverter drops.
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.
