Setup By Analog Input Signals (Vi/Ii Terminal - Toshiba TOSVERT VF-P7 Instruction Manual

7. 3. 2 Setup by analog input signals (VI/II terminal)

Connect current signal (4 to 20 mADC) to the terminal II or voltage signal (0 to 10 VDC) to the terminal VI
so that the inverter can be run and stopped with external commands.
