Parameter
For 3-wire terminal commands, there are start, stop and forward/reverse operations. They are used to
start and stop the inverter via an automatic reset contact such as a pushbutton switch.
Operation start command can be given from [STA] terminal and stop command from [STP] terminal.
To use the 3 wire function, the setting of the Run-command input source selection, 1st-motor [AA111]
and the input terminal setting selection [CA-01]-[CA-11] needs to be changed.
Select [AA111]=01 3 wire function. In this example, the 3 wire function is assigned to the input terminal
function in the following way.
*1. Set the terminals as the terminal No. 7 [CA-07]=016, No. 8 [CA-08]=017, No. 9 [CA-09]=018.
Operation can be started/stopped by making the 016 [STA]/017 [STP] terminal function ON/OFF on the
control circuit terminal block of the inverter.
018 [F/R] terminal function switches forward and reverse rotations by the contact.
The terminal action is made in the following way.
