Command/Reference Input From the Control Circuit Terminal Block
Operates the Inverter by connecting the external signals (frequency setting volume, switch,
etc.) to the control circuit terminal block.

*1 Allocate 16: FV/FI (Analog input switch) to a multi-function input to use as the voltage setting. If terminal
FV/FI is not allocated, the frequency reference becomes the sum of voltage input (FV) and current input
(FI). To use only one of voltage or current, therefore, short the other analog input to the SC terminal.
*2 This wiring diagram shows an example of using the built-in power supply of the Inverter. If an external
power supply is used, refer to "Connection to Programmable Controller (PLC)" on page 2-22.
Operation
Refer to "Test Run" on page 3-10.
