

Set the monitor to be displayed on the operation panel (FR-DU07-CNV) and parameter unit (FR-PU07) in Pr. 52 DU/PU
main display data selection.



Set the monitor to be output to the terminal FM (pulse train output) in Pr. 54 FM terminal function selection



Set the monitor to be output to the terminal AM (0 to 10VDC analog voltage output) in Pr. 50 AM terminal function selection



Refer to the following table and set the monitor to be displayed. (The signals marked 

 cannot be selected for monitoring)

The monitor to be displayed on the main screen of the operation panel (FR-DU07-CNV)/parameter unit (FR-PU07) can

be selected. 

In addition, signals to be output from the terminal FM (pulse train output) and AM (analog voltage output) can be

selected.
