 Monitoring and resetting cumulative power (Pr.170, Pr.891)
• When the cumulative power is monitored (Pr.52 = "25"), the output power monitor value is added up and is updated in 100
ms increments.
• The values are stored in EEPROM every 10 minutes. The values are also stored in EEPROM at power OFF or inverter
reset.
• Display increments and display ranges of the operation panel, parameter unit and communication (RS-485
communication, communication option) are as indicated below (when Pr.891 = "9999 (initial value)").
Operation panel, parameter unit
Range
0 to 999.99 kWh
1000.0 to 9999.9 kWh
10000 to 99999 kWh
*1 For the FR-F860-00680 or lower, the value is measured in 0.01 kWh increments and the upper five digits are displayed. For the FR-F860-01080
or higher, the value is measured in 0.1 kWh increments and the upper five digits are displayed.
For the FR-F860-00680 or lower, the cumulative energy up to 999.99 kWh is displayed in 0.01 increments such as "999.99", and that of 1000
kWh or more is displayed in 0.1 increments such as "1000.0".
*2 The display in 0.01 kWh increments is available only for the FR-F860-00680 or lower.
• The decimal point position on the watt-hour meter can be shifted to left. The number of digits to be shifted is equal to the
setting of Pr.891. For example, when Pr.891 = "2", the cumulative power value 1278.56 kWh is displayed as 12.78 (in 100
kWh increments) on the operation panel, or displayed as 12 on a display used for monitoring via communication.
• When Pr.891 = "0 to 4", the meter stops at the maximum number. When Pr.891 = "9999", the meter returns to 0 and the
counting starts again.
• Writing "0" in Pr.170 clears the cumulative power monitor.
NOTE
• When Pr.170 is read just after "0" has been written in Pr.170, the setting "9999" or "10" is displayed.
 Monitoring cumulative energization time (Pr.563)
• When the cumulative energization time is selected as a monitor item (Pr.52 = "20"), the counter of cumulative energization
time since the inverter shipment accumulated every hour is displayed.
• The cumulative energization time is displayed in 0.001-hour increments until the cumulative time reaches one hour, and
then the time is displayed in 1-hour increments.
• The EEPROM is updated every minute until the cumulative energization time reaches one hour, and then the EEPROM is
updated every 10 minutes. The EEPROM is also updated at power OFF.
• When the cumulative energization time counter reaches 65535, it starts from 0 again. The number of times the cumulative
energization time counter reaches 65535 can be checked with Pr.563.
NOTE
• The cumulative energization time does not increase if the power is turned OFF after less than an hour.
