 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.
• Increments and ranges of monitoring on the operation panel or parameter unit and via communication (RS-485
communication or other communication with communication option installed) are as follows (when Pr.891 = "9999 (initial
value)").
On operation panel or parameter unit
Range
0 to 999.99 kWh
1000.0 to 9999.9 kWh
10000 to 99999 kWh
*1 For the FR-A820-03160(55K) or lower and FR-A840-01800(55K) or lower, the value is measured in 0.01 kWh increments and the upper five digits
are displayed. For the FR-A820-03800(75K) or higher and FR-A840-02160(75K) or higher, the value is measured in 0.1 kWh increments and the
upper five digits are displayed.
For the FR-A820-03160(55K) or lower and FR-A840-01800(55K) 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-A820-03160(55K) or lower and FR-A840-01800(55K) 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 Cumulative power monitor digit shifted times. 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.
