Meter setting and adjustment

• 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
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.

(Default setting)
When the optional frequency meter QS60T is
connected, this mode is selected.

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.
