4.2.81 FM terminal
You can monitor the inverter output frequency and output current via
the FM terminal on the control circuit terminal block. The FM terminal is
a pulse output terminal.
(1) FM siginal selection
Select the signal to be output from the FM terminal among those shown below.
If you select "03" (digital output frequency), connect a digital frequency counter to the FM terminal. To
monitor other output signals, use an analog meter.

*2 Digital current monitoring
If the output current matches the digital current monitor reference value (C030), the FM terminal will output
a signal indicating 1,440 Hz.
