Note 1: The signal output from the FM and AM terminal is an analog voltage signal or an analog current signal.
(positive (+) side output. In the case of output the signed data, the signal is added offset. Offset level is able
to adjust by H and H. If monitoring the output data with positive and negative voltage, you need
to use "expansion I/O card2 option".
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 either a full-scale 0~1mAdc ammeter or a full-scale 0~7.5Vdc (or 10Vdc)
voltmeter, if necessary.
Connect meters as shown below.

ŬIt is recommendable to use an ammeter with a current rating 1.5 or more times as high as the output current
rating of the inverter.
• Function
Inverter’s operation data is sent to the FM terminal (AM terminal) as analog voltage signals or analog current
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
.
