Note 1: The signal output from the FM and AM terminal is an analog voltage signal or an analog current 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 either a full-scale 0~1mAdc ammeter or a full-scale 0~7.5Vdc (or 10Vdc)
voltmeter, if necessary.
Connect meters as shown below.

It 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
” (AM terminal-connected meter adjustment ) parameter is used to calibrate the meter.
