Setup By Analog Input Signals (Vi/Ii Terminal - Toshiba Tosvert VF-AS1 Instruction Manual

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 (), VI/II
reference point 2 ()/frequency
().
 Connection and calibration of
frequency meter
Forward run
Connect a 1mAdc full-scale DC current
meter, 7.5Vdc full-scale DC voltmeter or
Reverse run
rectifier type AC voltmeter. For calibration
of the meter, refer to the Section 5.16.
