Monitor display and monitor output signals
Cumulative energizing power monitor and clear (Pr. 170, Pr. 891)
On the cumulative energizing power monitor (Pr. 52 = 25), the output power monitor value is
added up and is updated in 1h increments. The operation panel (FR-DU07), parameter unit (FR-
PU04/FR-PU07) and communication (RS-485 communication, communication option) display
units and display ranges are as indicated below:
Range
0–99.99kWh
100–9.999kWh
1000–9999kWh
Tab. 6-95: Units and range of the cumulative energizing monitor
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.
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.
The monitor data digit can be shifted to the right by the number set in Pr. 891. For example, if
the cumulative power value is 1278.56kWh when Pr. 891 = 2, the PU/DU display is 12.78 (dis-
play in 100kWh increments) and the communication data is 12.
If the maximum value is exceeded at Pr. 891 = 0 to 4, the power is clamped at the maximum
value, indicating that a digit shift is necessary. If the maximum value is exceeded at Pr. 891 =
9999, the power returns to 0 and is recounted.
Writing "0" to Pr. 170 clears the cumulative energizing power monitor.
NOTE
If "0" is written to Pr. 170 and Pr. 170 is read again, "9999" or "10" is displayed.
Cumulative energizing time and actual operation time monitor (Pr. 171, Pr. 563, Pr. 564)
On the cumulative energization time monitor (Pr. 52 = 20), the inverter running time is added up
every 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 numbers of monitor value exceeds 65535, it is added up from 0. You can check the num-
bers of cumulative energizing 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 actual operation time monitor. (Energizing time monitor can not
be cleared.)
NOTES
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.
