•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.

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 ￿￿￿￿ and ￿￿￿￿. 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)					5
	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.

Meter: Ammeter (default setting)

The reading of the ammeter fluctuates during calibration.

!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.
