Restart operation parameters
2.6.3 Monitoring reference (Pr. 55 , Pr. 56 )
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 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.
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 FM.

CAUTION
The maximum pulse train output of terminal FM is 2400 pulses/s. If Pr. 55 is not
adjusted, the output of terminal FM will be filled to capacity. Therefore, adjust
Pr. 55.
At power restoration after an instantaneous power failure, you can restart the
inverter without stopping the motor (with the motor coasting).
