Three-wire type (STF, STR, STOP signal)
The three-wire connection is shown below.
Turning the STOP signal ON makes start self-holding function valid. In this case, the forward/reverse rotation signal
functions only as a start signal.
If the start signal (STF or STR) is turned ON and then OFF, the start signal is held and makes a start. When changing the
direction of rotation, turn STR (STF) ON once and then OFF.
To stop the inverter, turning OFF the STOP signal once decelerates it to a stop.
When using the STOP signal, set "25" in any of Pr.178 to Pr.182 to assign function.
