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.)
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.

FM terminal meter
adjustment
Function
Inverter’s operation data is outputted to the FM terminal (AM terminal) as analog voltage
signals. The “FM terminal-connected meter adjustment ” (AM terminal-connected meter
adjustment ) parameter is used to calibrate the meter.
Meter : Frequency meter
(Default setting)
The reading of the
frequency meter fluctuates
during calibration.
Meter: Ammeter
(Default setting)
The reading of the
ammeter fluctuates during
calibration.
Use an ammeter capable of measuring up to a curren
t
1.5 times larger than the rated current of the inverter.
