Functions
Switching between Analog Current and VR via the FV/FI Terminal
Either Analog Voltage or Analog Current is Used
To minimize the effect of noise, allocate the FV/FI terminal even when either analog voltage or
current is used, and select either current or voltage by turning ON/OFF the terminal. If the FV/
FI terminal cannot be allocated, be sure to short the unused analog input terminal as shown
below.
