<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.

detection width.
Setting 16: Frequency Detection 4
Output closes whenever the output frequency is equal to or above the detection level set in L4-03. The output opens when the
output frequency falls below L4-03 minus the hysteresis set in L4-04. As the detection level L4-03 is a signed value, the
detection works in the specified direction only.
Status
Open Output frequency is below L4-03 minus L4-04 or has not exceeded L4-03 yet.
Closed Output frequency exceeded L4-03.
