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.
