Monitor display and monitor output signal
(4)
Cumulative power monitor and clear (Pr. 170)
On the cumulative power monitor (Pr. 52 = "25"), the output power monitor value is added up and is updated in 1h
increments.
The operation panel, parameter unit (FR-PU04/FR-PU07) and communication (RS-485 communication, communication
option) display increments and display ranges are as indicated below.
Operation Panel ∗1
Range
0 to 99.99kWh
100.0 to 999.9kWh
1000 to 9999kWh
∗1
Power is measured in the range 0 to 9999.99kWh, and displayed in 4 digits.
When the monitor value exceeds "99.99", a carry occurs, e.g. "100.0", so the value is displayed in 0.1kWh increments.
∗2
Power is measured in the range 0 to 99999.99kWh, and displayed in 5 digits.
When the monitor value exceeds "999.99", a carry occurs, e.g. "1000.0", so the value is displayed in 0.1kWh increments.
Writing "0" to Pr. 170 clears the cumulative power monitor.
REMARKS
If "0" is written to Pr. 170 and Pr. 170 is read again, "9999" or "10" is displayed.
(5)
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 monitored value exceeds 65535, it is added up from 0. You can check the numbers of cumulative energization time
monitor exceeded 65535h with Pr. 563 and the numbers of actual operation time monitor exceeded 65535h with Pr. 564.
Writing "0" to Pr. 171 clears the cumulative power monitor. (The cumulative time monitor can not be cleared.)
REMARKS
The actual operation time is not added up unless the inverter is operated one or more hours continuously.
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.
(6)
You can select the decimal digits of the monitor (Pr. 268)
As the operation panel display is 4 digits long, the decimal places may vary at analog input, etc. The decimal places can
be hidden by selecting the decimal digits.
In such a case, the decimal digits can be selected by 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 smaller than
0.99 is displayed as 0.
When 2 decimal places (0.01 increments) are monitored, the 0.01 decimal place is dropped and the monitor
1
displays the first decimal place (0.1 increments). The monitored digits in 1 increments are displayed as they are.
REMARKS
The number of display digits on the cumulative energization time (Pr. 52 = "20"), actual operation time (Pr. 52 = "23"), and
cumulative power (Pr. 52 = "25") does not change.
