.6.3 Monitoring reference
Set the frequency or
current which is
referenced when the
output frequency or
output current is selected
for the FM (AM) terminal.
•
The Japanese
version has the FM
terminal feature, and
the NA and EC
versions have the AM
terminal feature.

<Setting>
Refer to the above diagrams and set the frequency monitoring reference value in
Pr. 55 and the current monitoring reference value in Pr. 56.
Pr. 55 is set when Pr. 54 "FM (AM) terminal function selection" = "0" and Pr. 56 is set
when Pr. 54 = "1".
Set the Pr. 55 and Pr. 56 values so that the output pulse train output of terminal FM is
1440 pulses/s (the output voltage of terminal AM is 5V).
CAUTION
• The maximum pulse train output of terminal FM is 2400pulses/s. If Pr. 55 is not
adjusted, the output of terminal FM will be filled to capacity. Therefore, adjust Pr. 55.
• The maximum output voltage of terminal AM is 5VDC.
