Function assignment of external terminal and control
(2) 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
Pr. 178 to Pr. 184
to assign function.
(3) Start signal selection
3-wire connection example (
Pr. 250
= "9999")
3-wire connection example (
Pr. 250
= "8888")
REMARKS
When the JOG signal is turned ON to enable Jog operation, the STOP signal becomes invalid.
If the MRS signal is turned ON to stop the output, the self-holding function is not canceled.
