Output terminal closes when both conditions below are met.
• The output frequency (or the motor speed when using CLV or CLV/PM) is within the range of the speed agreement
detection level (L4-01) plus or minus the speed agreement detection width (L4-02).
• The output frequency (or the motor speed when using CLV or CLV/PM) is within the range of the frequency reference
plus or minus the speed agreement detection width (L4-02).
Status
One of the following conditions is true:
• Output frequency or motor speed is not within the range of L4-01 ±L4-02
Open
• Output frequency or motor speed is not within the range of the frequency reference ±L4-02
Both of the following conditions are true:
• Output frequency or motor speed is within the range of L4-01 ±L4-02
Closed
• Output frequency or motor speed is within the range of the frequency reference ±L4-02
Note: Frequency detection works in both forward and reverse. The value of L4-01 is used as the detection level for both directions.

Setting 4: Frequency Detection 1
Output opens when the output frequency or motor speed (CLV, CLV/PM) 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.
Status
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.
Note: Frequency detection works in both forward and reverse. The value of L4-01 is used as the detection level for both directions.
