Monitor display and monitor output signals Parameter

6.15.3 CA, AM terminal function selection (Pr. 55, Pr. 56, Pr. 867, Pr. 869)
For signal output, two different output terminals are available: analog current output terminal CA
and analog voltage output terminal AM. Set the reference of the signal output from terminal CA
and AM.
The above parameters allow its setting to be changed during operation in any operation
mode even if "0" (initial value) is set in Pr. 77 "Parameter write selection".
Frequency monitoring reference (Pr. 55)
Set the frequency to be referenced when the frequency monitor (output frequency/set
frequency) is selected for the terminal CA and terminal AM display.
●
Set the frequency when the current output at terminal CA is 20mA DC. The analog current
output at terminal CA and the inverter output frequency are proportional. (The maximum
output current is 20mA DC.)
●
Set the frequency (output frequency/set frequency) when the voltage output at terminal AM
is 10V DC. The analog voltage output at terminal AM and the frequency are proportional.
(The maximum output voltage is 10V DC.)
