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/PUmain display data selection".
●
Set the monitor to be output to the terminal CA ((analog current output) in Pr. 54 "CA terminal
function selection".
●
Set the monitor to be output to the terminal AM (analog voltage output (0 to 10VDC voltage
output)) in Pr. 158 "AM terminal function selection".
