7. 2 Applied operation with input and output signals
(operation by the terminal board)
7. 2. 1 Functions of input terminals (in case of sink logic)
Signals that are supplied to control input terminals from the programmable controller, etc. are
used to operate or set up the inverter.
Since function of each contact input terminal is selectable from 136 functions, this inverter
makes it possible to design a system flexibly.

This function is activated when the input terminal
and CC (common) are short-circuit, and it is used
for forward rotation, reverse rotation, preset
speed operation, etc.
This function is activated when the input terminal
and CC (common) are open-circuit, and it is used
for standby signal, reset signal, etc.
