Ca, Am Terminal Function Selection (Pr. 55, Pr. 56, Pr. 867, Pr. 869) - Mitsubishi Electric FR-F740 EC Instruction Manual

Monitor display and monitor output signals
6.10.3

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 output terminal AM. You can select the signals output to the terminals CA, AM.

The above parameters can be set when Pr. 160 = 0.
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 and inverter output frequency at terminal CA 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 and frequency at terminal AM are proportional. (The
maximum output voltage is 10V DC.)
