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.
