Note 1: The signal output from the FM and AM terminal is an analog voltage signal. (positive (+) side output. For
signed data, an absolute value is output. To output data with positive and negative sings, you need to use two
extended terminal boards (optional).)
Note 2: To the FM terminal, connect either a full-scale 0~1mAdc ammeter or a full-scale 0~7.5Vdc (or 10Vdc)
voltmeter, if necessary. The FM terminal can also be used as a 0(4)~20mAdc output terminal. To the AM
terminal, connect a full-scale 0-1mAdc ammeter.
Connect meters as shown below.

• Function
Inverter’s operation data is sent to the FM terminal (AM terminal) as analog voltage signals. To display inverter’s
operation data, connect a meter to this terminal. The “FM terminal-connected meter adjustment HO” (AM
terminal-connected meter adjustment CO) parameter is used to calibrate the meter
.
