 Selecting the functions of the VI terminal between analog input and logic input
The functions of the VI terminal can be selected between analog input and logic input by changing
parameter settings (). (Factory default setting: Analog input 0-10V)
Be sure to connect a resistor between P24 and VI terminals in case of sink logic, between VI and CC
terminals in case of source logic. (Recommended resistance: 4.7k-1/2W)
When using VI terminal as a logic input terminal, set the parameter = and connect as following
schematics.
If no resistor is inserted, logic input will be left always ON, which is very dangerous.
2
Switch between analog input and logic input before connecting the terminals to the control circuit terminals.
Otherwise the inverter or devices connected to it may be damaged.
