Monitor display and monitor output signals
6.10.3 Reference of the terminal AM (analog voltage output) (Pr. 55, Pr. 56)
Analog voltage output from the terminal AM is available. Set the reference of the signal output
from terminal 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 frequen-
cy) is selected for the terminal AM display. Set the full scale value when outputting the frequency
monitor from terminal AM.
● 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.).
