<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 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.
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.

2.7 Restart operation function

2.7.1 Restart setting (Pr. 57
At power restoration after an instantaneous power failure, you can restart the
inverter without stopping the motor (with the motor coasting).
