The internal potentiometer to the inverter is used for setting frequencies. Turning
the notches clockwise raises the frequency.
A frequency command is set by means of a signal from an external input device
(VIA terminal: 0-10Vdc or 4-20mAdc).
An external signal (VIB terminal: 0-10Vdc) is used to specify a frequency com-
mand.
Press the key or the
sion panel (optional) to set frequency.
Frequencies are set by commands from an external control unit.
Terminals are used to specify an up/down frequency command.
The sum of the values entered through the VIA and VIB terminals is used as a
frequency command value.
