Setting 0: During Run
Output closes when the drive is outputting a voltage.
Status
Open Drive is stopped.
Closed An Up/Down command is input or the drive is during deceleration or during DC injection.
Setting 1: Zero Speed
Terminal closes whenever the output speed or motor speed (CLV, CLV/PM) falls below the minimum output speed set to
E1-09 or S1-01.
Status
Open The operating speed is faster than the minimum output frequency (E1-09) and the zero speed level at stop (S1-01).
Closed The operating speed is below the minimum output frequency (E1-09) and the zero speed level at stop (S1-01).
Note: When using CLV or CLV/PM control modes, the zero speed level is defined by S1-01. In all other control modes, the zero speed
level is the minimum output speed set to E1-09.

Setting 2: Speed agree 1 (f
Closes whenever the actual output speed (CLV, CLV/PM) is within the Speed Agree Width (L4-02) of the current speed
reference regardless of the direction.
Status
Open Output speed or motor speed does not match the speed reference while the drive is running.
Closed Output speed or motor speed is within the range of speed reference ±L4-02.
Note: Detection works in both directions, forward and reverse.
