Status
Open Output frequency or frequency reference are outside the range of L4-01 ± L4-02.
Closed Output frequency and the frequency reference are both within 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
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.
Frequency
Detection 1 <1>
<1> This is the time chart when L4-07, Speed Agree Detection Selection, is set to 1 (Detection always enabled). The default
setting for L4-07 is 0 (No detection during baseblock). When L4-07 is set to 0, the terminal opens during baseblock.
Refer to L4-01/02: Speed Agreement Detection Level and Detection Width on page 227
width.
Setting 5: Frequency Detection 2
Output closes whenever the output frequency is equal to or above the detection level set in L4-01. The output opens when the
output frequency falls below L4-01 minus the hysteresis set in L4-02.
Status
Open Output frequency is below L4-01 minus L4-02 or has not exceeded L4-01.
Closed Output frequency exceeded L4-01.
Note: The detection works in both forward and reverse. The value of L4-01 will be used as the detection level for both directions.
