(T) Multi-Function Input Terminal Parameters
422
PARAMETERS
 3-wire type (STF, STR, STP (STOP) signal)
• The following figure shows the connection in 3-wire type.
• Start self-holding function is enabled when the STP (STOP) signal is turned ON. In such case, forward/reverse signal will
only operate as start signal.
• Even if start signal (STF or STR) is turned ON and then OFF, the start signal will be maintained and it will start. To change
the rotation direction, turn STR (STF) ON once and then OFF.
• The inverter will perform deceleration stop by turning the STP (STOP) signal OFF once.
NOTE
• The STP (STOP) signal is assigned to the terminal STP (STOP) by the initial setting. Set "25" in any of Pr.178 to Pr.189 to
assign the STP (STOP) signal to another terminal.
• When the JOG operation is enabled by turning ON the JOG signal, STOP signal will be disabled.
• Even when the output is stopped by turning ON the MRS signal, self-holding function is not canceled.
 Start signal selection
