* There are two types of function: the function that conforms to commands selected by EOQF, and the function
that conforms only to commands from the terminal board. See the table of input terminal function selection in
Chapter 11.
* When priority is given to commands from a linked computer or terminal board, they have priority over the set-
ting of EOQF.

:
Potentiometer
The internal potentiometer to the inverter is used for setting frequencies. Turning
the notches clockwise raises the frequency.
:
VIA input
A frequency command is set by means of a signal from an external input device
(VIA terminal: 0-10Vdc or 4-20mAdc).
:
VIB input
An external signal (VIB terminal: 0-10Vdc) is used to specify a frequency com-
mand.
:
Operation panel
Press the key or the key on either the operation panel or the expan-
sion panel (optional) to set frequency.
:
Communication
Frequencies are set by commands from an external control unit.
:
UP/DOWN frequency
Terminals are used to specify an up/down frequency command.
:
VIA+VIB (Override)
The sum of the values entered through the VIA and VIB terminals is used as a
frequency command value.
, No matter what value the command mode selection EOQF and the frequency setting mode selection
HOQF are set to the control input terminal functions described below are always in operative state.
• Reset terminal (default setting: RES, valid only for tripping)
• Standby terminal (when programmed by programmable input terminal functions).
• External input tripping stop terminal command (when so set using the programmable input terminal func-
tion)
