Agree 1)
Closes when the actual output frequency or motor speed 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 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.
Note: Detection works in forward and reverse.

Agree 1)
Closes when the actual output frequency or motor speed 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.

Setting 4: Frequency Detection 1
The output opens when the output frequency or motor speed rises above the detection level set in L4-01 plus the detection
width set in L4-02. The terminal remains open until the output frequency or motor speed fall below the level set in L4-01.
