The time can be set. The time can only be updated while the inverter power is ON.
The real time clock function is enabled using an optional LCD operation panel (FR-LU08).

Simple clock function
When the year, month, day, time and minute are set in the parameters, the inverter counts the date
and time. The date and time can be checked by reading the parameters.
NOTES The clock's count-up data is saved in the inverter's EEPROM every 10 minutes.
Because the date and time are cleared after turning OFF the control circuit power supply, the clock
function must be reset after turning ON the power supply. Use a separate power supply, such as
an external 24 V power supply, for the control circuit of the simple clock function, and supply
power continuously to this control circuit.
In the initial setting, inverter reset is performed if supplying power to the main circuit is started
when power is supplied only to the control circuit. Then, the clock information stored in EEPROM
is restored. Reset at the start of supplying power to the main circuit can be disabled by setting Pr.
30 "Regenerative function selection". (Refer to page 5-713.)
The set clock is also used for functions such as faults history.
