Setup By Analog Input Signals (Rr/S4 Terminal - Toshiba Tosvert VF-AS1 Instruction Manual

7.3.1 Setup by analog input signals (RR/S4 terminal)

If a potentiometer (1~10kΩ-1/4W) for setting up frequency is connected with the RR/S4 terminal, the inverter can
be run and stopped with external commands.
For bringing this function into practice, connect a potentiometer to the terminals of PP, RR/S4 and CC so as to
divide the reference voltage (10Vdc) at the terminal PP and to input 0 to 10Vdc of divided voltage between the
RR/S4 and CC terminals.
If analog voltage signal of 0 to 10Vdc is input between the terminals of RR/S4 and CC, frequency can be set up
without connection of a potentiometer.

 Run/stop setup
To control switching between forward run

(F) and reverse run (R), and stop by
external commands.
IM
 Setup of frequency setting signal and
running frequency characteristic
To set up frequency setting signal to be
input to the potentiometer (RR/S4
terminal) and characteristic of running
frequency.
Frequency characteristic is set up at the
two points of RR/S4 reference point 1
()/frequency (), RR/S4
reference point 2 ()/frequency
().
 Connection and calibration of
Forward run
frequency meter
Connect a 1mAdc full-scale DC current
Reverse run
meter, 7.5Vdc full-scale DC voltmeter or
rectifier type AC voltmeter. For
calibration of the meter, refer to the
Section 5.16.
