 3-wire type (STF signal, STR signal, STP (STOP) signal)
• The following figure shows the 3-wire type connection.
• The self-holding function is enabled when the STP (STOP) signal is turned ON. In such case, the forward/reverse signal
is simply used as a start signal.
• Even if a start signal (STF or STR) is turned ON and then OFF, the start command remains valid and the motor operation
continues. To change the rotation direction, turn the STR (STF) signal ON once and then OFF.
• In order to decelerates the motor to a stop, turn OFF the STP (STOP) signal once.

3-wire type connection example (Pr.250 = "9999")
NOTE
• Set "25" in any of Pr.178 to Pr.182 to assign the STP (STOP) signal to another terminal.
• When the JOG operation is enabled by turning ON the JOG signal, the STOP signal will be disabled.
• Even when the output is stopped by turning ON the MRS signal, the self-holding function is not canceled.
