Meter setting and adjustment

• Function
The FM/OUT terminal can be switched between meter output (PWM output) and open
collector. When connecting a meter to the FM/OUT terminal, set the
number other than -1 (open collector output) and connect the meter between FM/OUT
(positive side) and CC (negative side).
If you want to connect a meter to the inverter, choose a full-scale 0~1mAdc ammeter or a
full-scale 0~7.5Vdc-1mA voltmeter.
The meter output of VFNC1 may have some errors because of PWM waveform.
Especially if the meter output is near 0, the errors may be increased.
