 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. (LED
of Hz blinks during stop and is lit during operation.)
Pr.52 setting
0
100
*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)
• Use Pr.992 to select the monitor that appears when the setting dial on the operation panel (FR-DU08) 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.
• When Pr.992 = "100", the set frequency is displayed during stop, and output frequency is displayed 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.992 = "5".
 Monitoring I/O terminals on the operation panel (FR-DU08) (Pr.52, Pr.774
to Pr.776, Pr.992)
• When Pr.52 (Pr.774 to Pr.776, Pr.992) = "55 to 57", the I/O terminal state can be monitored on the operation panel (FR-
DU08).
• When a terminal is ON, the corresponding LED segment is ON. The center LED segments are always ON.

• On the I/O terminal monitor, the upper LEDs indicate the input terminal status, and the lower LEDs indicate the output
terminal status.
