7.2 Applied operation with input and output signals (operation by terminal board)
7.2.1 Functions of input terminals (in case of sink logic)
Use the above parameters to send signals from an external programmable controller to various control input
terminals to operate and/or set the inverter.
The desired contact input terminal functions can be selected from about 80 types. This gives system design flexibility.

Note 1:RR/S4 terminal become enable when SW3 is switch to S4.
Note 2: When , and (Always ON function selection 1~3) are selected, selected function is
generally activated regardless of positive or negative logic.
Note 3: ~ is for use of expansion terminal board option unit.
Connection method
1) In case of positive logic (a-contact) input
Inverter
A-contact switch
CC
Input terminal
This function is activated when the input
terminal and CC (common) are short-circuited.
Use this function to specify forward/reverse
run or a preset speed operation.
2) In case of negative logic (b-contact) input
B-contact switch
CC
Input terminal
This function is activated when the input
terminal and CC (common) are open-circuit.
Use this function to specify operation standby
signal or reset signal.
