Closes whenever the actual output frequency 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 frequency reference are outside the range of L4-01 ± L4-02.
Closed Output frequency and the frequency reference are both with in the range of L4-01 ± L4-02.
Note: The detection works in both forward and reverse. The value of L4-01 will be used as the detection level for both directions.

Setting 4: Frequency Detection 1
Output is
closed as long as the output frequency is below the detection level set in L4-01 plus the hysteresis set in L4-02.
It closes when the output frequency falls below L4-01.
Status Description
Open Output frequency exceeded L4-01 + L4-02.
Closed Output frequency is below L4-01 or has not exceeded L4-01 + L4-02.
Note: The detection works in both forward and reverse. The value of L4-01 will be used as the detection level for both directions.
