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.

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.
