Setup By Analog Input Signals (Rr/S4 Terminal - Toshiba VF-PS1 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.

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

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
