6.2 Selection of input signals

6.2.1Changing standby signal function

 ：ST (standby) signal selection

・Function

This parameter is used to set the function of the standby signal (ST).

1)Normal setting (Standby if ST and CC are connected (ON), gate OFF if they are disconnected (OFF) (coast stop)

2)Always ON

3)Interlocked with F/R (Forward/reverse run if F/R and CC are connected, coast stop if they are disconnected)

	＊The inverter is shipped with
ON	terminals ST and CC shorted
OFF	with a bar. Remove the
ON	shorting bar when using
OFF	these terminals.

2) Always-ON

The inverter is always on standby regardless of the status of the terminal ST. The terminal ST can be assigned to another function. In this mode, the motor slows down from the set frequency speed to a stop in the predetermined deceleration time.

3) Interlocked with terminal F (forward)/R (reverse)

Breaking the connection of the operation frequency terminal (F/R) causes the motor to coast

to a stop. (Free-run stop)

＊The inverter is shipped with terminals ST and CC shorted with a bar. Remove the shorting bar when using these terminals.

 ：Priority selection (both F-CC, R-CC is ON)

・Function

This parameter is used to select the operation to which priority is given when F-CC and R- CC are closed simultaneously.
