*17 Parameter setting is not valid to set the item as the main monitor item on the LCD operation panel (FR-LU08). Use the monitor function of the
FR-LU08 for the setting.
 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 and fault display can be
selected in sequence by pressing the SET key.
• 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.
• The monitor displayed at power ON is the first monitor (the output frequency monitor, according to the initial value). Display
the monitor you want to display on the first monitor and hold down the SET key for 1 second. To return to the output
frequency monitor, display the output frequency monitor and hold down the SET key for 1 second.
Power-on monitor (first monitor)
Output frequency monitor
For example, when Pr.52 = "20" (cumulative energization time), the monitor is displayed on the operation panel as shown
below.
• Power-on monitor (first monitor)
Output frequency monitor
• 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
• On the operation panel, the Hz LED is lit while displaying the output frequency, the Hz LED blinks when displaying the set
frequency.
• When the operation panel is used, the displayed units are Hz and A only, and the others are not displayed.
 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. (The Hz
LED blinks during stop and is lit during operation.)

During running
*1 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.
 Operation panel setting dial push display (Pr.992) (only for the standard
model)
• Use Pr.992 to select the monitor that appears when the setting dial on the operation panel is pushed.
• When Pr.992 = "0 (initial value)", keep pressing the setting dial when in PU operation mode or External/PU combined
operation mode 1 (Pr.79 Operation mode selection = "3") to show the presently set frequency.
