Toshiba VF-A7 Functions of input terminals in case of sink logic, Control terminal board

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.

CC

★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.
