Monitor display for operation panel (Pr.52, Pr.774 to Pr.776)
• When Pr.52 = "0" (initial value), the monitoring of output frequency, output current, output voltage, 3-line monitor, and fault
display can be selected in sequence by pressing
• The Load meter, Motor excitation current and Motor load factor are displayed on the second monitor (output current)
position, among the monitors set in Pr.52. Other monitors are displayed in the third monitor (output voltage) position.
• Pr.774 sets the output frequency monitor, Pr.775 sets the output current monitor, and Pr.776 sets the monitor
description to be displayed at the output voltage monitor position. When Pr.774 to Pr.776 = "9999" (initial value), the Pr.52
setting value is used.
NOTE
• For the details of the operation panel, refer to the instruction manual of the operation panel (FR-LU08).
Displaying the set frequency during stop (Pr.52)
• When Pr.52 = "100", the set frequency is displayed during stop, and output frequency is displayed during running. ("Hz" is
highlighted during stop.)
Pr.52 setting Status
0 During running/stop
During stop
100
Running

Displays the frequency that is output when the start command is ON. The value considers the maximum/minimum frequency and frequency
jumps. It is different from the frequency setting displayed when Pr.52 = "5".
NOTE
• During an error, the output frequency at error occurrence appears.
• During output shutoff by the MRS signal, the values displayed are the same as during a stop.
• During offline auto tuning, the tuning state monitor takes priority.
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 stored in EEPROM every 10 minutes. The values are also stored in EEPROM at power OFF or inverter
reset.
• 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 0.01 kWh
1000.0 to 9999.9 kWh 0.1 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.
