7.3.2 Setup by analog input signals (VI/II terminal)
Connect current signal (4 (0) to 20mAdc) or voltage signal (0 to 10Vdc) to the terminal II so that the inverter can be
run and stopped with external commands.

Run/stop setup
To control switching between forward run
(F) and reverse run (R), run and stop by
external commands.
Setup of frequency setting signal and
running frequency characteristic
To set up frequency setting signal to be
input to the external signal (VI/II terminal)
and characteristic of running frequency.
Frequency characteristic is set up at the
two points of VI/II reference point 1
(

)/frequency (
H
), VI/II
reference point 2 (H)/frequency
(CKH).
Connection and calibration of
frequency meter
Connect a 1mAdc full-scale DC current
meter, 7.5Vdc full-scale DC voltmeter or
rectifier type AC voltmeter. For calibration
of the meter, refer to the Section 5.16.
