Cumulative Power Monitor And Clear; Cumulative Energization Time And Actual Operation Time Monitor; Hiding The Decimal Places For The Monitors - Mitsubishi FR-A800 Instruction Manual

Cumulative power monitor and clear (Pr.170, Pr.891)
• On the cumulative power monitor (Pr.52 = "25"), the output power monitor value is added up and updated in 100 ms
increments. (The values are saved in EEPROM every hour.)
• Display increments and display ranges of the operation panel, parameter unit and communication (RS-485 communication,
communication option) are as indicated below.
Operation panel, parameter unit
Range
0 to 999.99 kWh
1000.0 to 9999.9 kWh
10000 to 99999 kWh

Power is measured in the range of 0 to 99999.99 kWh, and displayed in five digits.When the monitor value exceeds "999.99", a carry occurs,
for example "1000.0", so the value is displayed in 0.1 kWh increments.
• The monitor data digit can be shifted to the right by the number of Pr.891.
For example, if the cumulative power value is 1278.56 kWh when Pr.891 = "2", the operation panel display is 12.78
(display in 100 kWh increments) and the communication data is 12.
• If the maximum value is exceeded at Pr.891 = "0 to 4", the monitor value is clamped at the maximum value, indicating that
a digit shift is necessary. If the maximum value is exceeded at Pr.891 = "9999", the monitor value returns to 0, and the
counting starts again.
• Writing "0" in Pr.170 clears the cumulative power monitor.
NOTE
• If "0" is written to Pr.170, and Pr.170 is read again, "9999" or "10" is displayed.
Cumulative energization time and actual operation time monitor (Pr.171,
Pr.563, Pr.564)
• Cumulative energization time monitor (Pr.52= "20") accumulates energization time from shipment of the inverter every one
hour.
• On the actual operation time monitor (Pr.52 = "23"), the inverter running time is added up every hour. (Time is not added up
during a stop.)
• If the number of monitor value exceeds 65535, it is added up from 0. Pr.563 allows the user to check how many times the
cumulative energization time monitor has exceeded 65535h. Pr.564 allows the use to check how many times the actual
operation time monitor has exceeded 65535h.
• Writing "0" in Pr.171 clears the actual operation time monitor. (The cumulative energization time monitor cannot be
cleared.)
NOTE
• The cumulative energization time does not increase if the power is turned OFF after less than an hour.
• The actual operation time does not increase if the cumulative running time before power OFF is less than an hour.
• If "0" is written to Pr.171 and Pr.171 is read again, "9999" is always displayed.Setting "9999" does not clear the actual
operation time meter.
Hiding the decimal places for the monitors (Pr.268)
• As the operation panel (FR-DU08) display is 5 digits long, the decimal places may vary during analog input, etc. The
decimal places can be hidden by selecting the decimal digits with Pr.268.
Pr.268 setting
9999 (initial value) No function
For the first or second decimal places (0.1 increments or 0.01 increments) of the monitor, numbers in the first
0 decimal place and smaller are rounded to display an integral value (1 increments). The monitor value equal to or
smaller than 0.99 is displayed as 0.
When monitoring with the second decimal place (0.01 increments), the 0.01 decimal place is dropped and the
1 monitor displays the first decimal place (0.1 increments). When monitoring with the first decimal place, the display
will not change.
