☆The following control input terminals are always operative, no matter how the EOQF parameter

(command mode selection) and the HOQF parameter (frequency setting mode selection) are

set.

　• Reset terminal (enabled only when a trip occurs.)

　• Standby terminal

　• External input trip stop terminal

☆Before changing the setting of the EOQF parameter (command mode selection) or the HOQF

parameter (frequency setting mode selection), be sure to put the inverter o ut of operation. (When

H is set to , the settings of these parameters can be changed even during operation.)

•There are two kinds of functions: function of responding to signals from the device specified with

the HOQF parameter and function of responding to signals from the terminal board only.

•When the highest-priority command is entered from an external device or a terminal board, it

takes priority over commands from the device specified with the HOQF parameter.

5.2 Meter setting and adjustment

HOUN : FM/OUT terminal functions selection

HO : Meter 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 HOUN parameter to a

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-sc ale 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.

*To switch between current input and voltage input, use the H parameter

(Analog input / logic input function selection).
