7.3.1 Setup by analog input signals (RR/S4 terminal)
If a potentiometer (1~10k-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.
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
(

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.
