Status Description
Open Output frequency is more than or equal to the minimum output frequency set to E1-09 or b2-01
Closed Output frequency becomes less than the minimum output frequency set to E1-09 or b2-01
Note: When using CLV or CLV/PM control modes, the output terminal closes when the motor speed becomes less than or equal to the zero speed
level set for b2-01. In all other control modes, the output terminal closes when the output frequency becomes less than or equal to the
minimum output frequency set for E1-09.

Closes when the actual output frequency or motor speed (CLV, CLV/PM) is within the Speed Agree Width (L4-02) of the
current frequency reference regardless of the direction.
Status Description
Open Output frequency or motor speed is outside the range of frequency reference ±L4-04.
Closed Output frequency or motor speed is within the range of frequency reference ±L4-02.
Note: Detection works in forward and reverse.

Agree 1)
Closes when the actual output frequency or motor speed (CLV, CLV/PM) and the frequency reference are within the speed
agree width (L4-02) of the programmed speed agree level (L4-01).
Status Description
Open Output frequency or motor speed and frequency reference are not both within the range of L4-01 ±L4-02.
Closed Output frequency or motor speed and the frequency reference are both within the range of L4-01 ±L4-02.
Note: Frequency detection works in forward and reverse. The value of L4-01 is used as the detection level for both directions.
