Restart operation parameters
2.6.3 Monitoring reference (Pr. 55 , Pr. 56 )
<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 "AM terminal function selection" = "0" and Pr. 56 is set when
Pr. 54 = "1".
In Pr. 55 and Pr. 56, set the frequency and current at which the output voltage of
terminal AM will be 5V.
2.7 Restart operation parameters
2.7.1 Restart setting (Pr. 57 , Pr. 58 , H6 )
The parameter number in parentheses is the one for use with the parameter unit (FR-PU04).
Set the frequency
or current which
is referenced
when the output
frequency or
output current is
selected for the
terminal AM.
