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

Refer to L4-01, L4-02: Speed Agreement Detection Level and Detection Width on page 210 for more instructions.
Setting 4: Frequency Detection 1
Output opens when the output frequency or motor speed (CLV) 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 falls below the level
set in 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 The output frequency is outside the range “L4-01 ± L4-02” or outside the range “frequency reference ±L4-02”.
Closed The output frequency is within the range “L4-01 ± L4-02” and also within the range “frequency reference ±L4-02”.
Status Description
Open Output frequency or motor speed exceeded L4-01 + L4-02.
Closed Output frequency or motor speed is below L4-01 or has not exceeded L4-01 + L4-02.
