Frequency monitoring reference (Pr. 55)
Set the full scale value when outputting the frequency monitor from terminal FM.
Set the frequency to be indicated as the full scale value on the frequency meter (1mA analog meter) connected between
terminal FM and SD. (For example, 60Hz or 120Hz.)
Set the inverter output frequency (set frequency) at which the pulse speed of the FM output is 1440 pulses/s.
The pulse speed and inverter output frequency are proportional to each other. (The maximum pulse train output is 2400
pulses/s.)
