Monitor display and monitor output signal
(1) Monitor description list (Pr. 52)
⋅Set the monitor to be displayed on the operation panel (FR-DU07) and parameter unit (FR-PU04/FR-PU07) in Pr.
52 DU/PU main display data selection.
⋅Set the monitor to be output to the terminal CA (analog output (0 to 20mADC current output)) in Pr. 54 CA terminal
function selection.
⋅Set the monitor to be output to the terminal AM (analog output (0 to 10VDC voltage output)) in Pr. 158 AM terminal
function selection.
⋅Refer to the following table and set the monitor to be displayed. (The signals marked × cannot be selected for
monitoring)
