7. 3. 1 Setup by analog input signals (RR terminal)
If a variable resistor (1-10 kΩ, 1/4 W) for setting up frequency is connected with the RR 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 and
CC so as to divide the reference voltage (10 VDC) at the terminal PP and to input 0 to 10 VDC of
divided voltage between the RR and CC terminals.
If analog voltage signal of 0 to 10 VDC is input between the terminals of RR and CC, frequency
can be set up without connection of a potentiometer.

Run/stop setup
To control switching between forward
rotation (F) and reverse rotation (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 potentiometer (RR terminal)
and characteristic of running frequency.
Frequency characteristic is set up at
the two points of RR reference point #1
()/frequency(), RR
reference point #2()/frequency
().
Connection and calibration of
frequency meter
Connect a 1 mADC full-scale DC
current meter, 7.5 VDC full-scale DC
voltmeter or rectifier type AC voltmeter.
For calibration of the meter, refer to the
section 5.4.
