Parameters
Real time clock function
Fig. 5-75:
● When the FR-LU08 is connected to the inverter, the internal clock of the inverter can be synchro-
nized with the clock of FR-LU08. (Real time clock function)
With a battery (CR1216), the FR-LU08 time count continues even if the main power of the inverter
is turned OFF. (The time count of the inverter internal clock does not continue when the inverter
power is turned OFF.)
● To adjust the clock of FR-LU08, use the FR-LU08 and set Pr. 1006 to Pr. 1008.
NOTES Time adjustment between the inverter internal clock and the FR-LU08 is performed every one
minute.
When the FR-LU08 clock is initialized after the battery is exhausted for example, the inverter inter-
nal clock is valid.
