Closes whenever 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.
Note: Detection works in both directions, forward and reverse.

Closes whenever 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).
Note: Frequency detection works in both forward and reverse. The value of L4-01 is used as the detection level for both directions.

Status Description
Open Output frequency or motor speed does not match the frequency reference while the drive is running.
Closed Output frequency or motor speed is within the range of frequency reference ±L4-02.
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.
