Real Time Clock Function - Mitsubishi Electric FR-A820-00046 (0.4K) Instruction Manual

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.
NOTE
• The clock's count-up data is saved in the inverter's EEPROM every 10 minutes.
• The clock does not count up while the control circuit power supply is OFF. 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
• The set clock is also used for functions such as faults history.
 Real time clock function
• When the FR-LU08 is connected to the inverter, the internal clock of the inverter can be synchronized 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.
NOTE
• 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 internal clock is valid.
