Description of parameters
(3) Cumulative power monitor and clear (Pr. 46, Pr. 48)
On the cumulative power monitor (Pr. 52 = "8"), the input power is accumulated and updated in 100ms increments. (The
value is stored in EEPROM every 1h.)
Display increments and display ranges of the operation panel (FR-DU07-CNV), parameter unit (FR-PU07) and
communication (RS-485 communication) are as indicated below.
The monitor data digit can be shifted to the right by the number of Pr. 48.
For example, if the cumulative power value is 1278.56kWh when Pr. 48 = "2", the PU/DU display is 12.78 (display in
100kWh increments) and the communication data is 12.
If the maximum value is exceeded at
Pr. 48
= "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. 48
= "9999", the power returns to 0, and the counting starts again.
Writing "0" in Pr. 46 clears the cumulative power monitor.
(4) Input power (with regenerative display) (Pr. 52 = "10")
On the input power monitor (with regenerative display) (Pr. 52 = "10"), the input power to the converter is displayed with a
sign.
On the operation panel (FR-DU07-CNV), the input power is displayed as a positive value (no sign) during the power
driving and displayed with a minus sign during the regenerative driving.
When the monitored value is 100kW or more, the displayed unit is 1kW. When the power value is 1000kW or more, it is
limited at 999kW. When the power value is -1000kW or less, it is limited at -999kW.
Positive value (no sign) is displayed in the input power display on the communication option and FR-PU07 during power
driving and regenerative driving.
(5) Cumulative energization time monitor(Pr. 47)
On the cumulative energization time monitor (Pr. 52 = "9"), the energization time has been cumulated every hour since the
shipment of the converter.
If the number of monitor value exceeds 65535, it is added up from 0. You can check how many times the cumulative
energization time monitor exceeded 65535h with Pr. 47.

Power is measured in the range of 0 to 9999.99kWh, and displayed in four 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 of 0 to 99999.99kWh, and displayed in five digits.
When the monitor value exceeds "999.99", a carry occurs, e.g. "1000.0", so the value is displayed in 0.1kWh increments.
REMARKS
If "0" is written to Pr. 46, and Pr. 46 is read again, "9999" or "10" is displayed.
REMARKS
Input power (with regenerative display) (Pr. 52 ="10") cannot be assigned to a FM/AM analog output terminal.
