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 120 types. This gives system design flexibility.


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.

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.
