Refer to L4-03, L4-04: Speed Agreement Detection Level and Detection Width (+/-) on page 229 for more details.
Setting 15: Speed detection 3
Output opens when the output speed or motor speed (CLV, CLV/PM) rises above the detection level set in L4-03 plus the
detection with set in L4-04. The terminal remains open until the output speed or motor speed falls below the level set in
L4-03. As the detection level L4-03 is a signed value, the detection works in the specified direction only.

Setting 16: Speed detection 4
Output closes whenever the output speed or motor speed (CLV, CLV/PM) is above the detection level set in L4-03. The
terminal remains closed until the output speed or motor speed falls below L4-03 minus the setting of L4-04. As the
detection level L4-03 is a signed value, speed detection works in the specified direction only.
Status Description
Open Output speed or motor speed exceeded L4-03 plus L4-04.
Closed Output speed or motor speed is below L4-03 or has not exceeded L4-03 plus L4-04 yet.
<1> This is the timing 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 = 0, the terminal opens during baseblock.
Status Description
Open Output speed or motor speed is below L4-03 minus L4-04 or has not exceeded L4-03 yet.
Closed Output speed or motor speed exceeded L4-03.
