Setting 4: Speed Detection 1
Output opens when the output 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 speed falls below the level set in L4-01.
Note: Detection works in both forward and reverse. The value of L4-01 is used as the detection level for both directions.

Refer to L4-01, L4-02: Speed Agreement Detection Level and Detection Width on page 229 for more details.
Setting 5: Speed Detection 2
Output closes whenever the output speed or motor speed (CLV, CLV/PM) is above the detection level set in L4-01. The
terminal remains closed until the output speed or motor speed falls below L4-01 minus the setting of L4-02.
Note: Detection works in both forward and reverse. The value of L4-01 is used as the detection level for both directions.

Status Description
Open Output speed or motor speed exceeded L4-01 + L4-02.
Closed Output speed or motor speed is below L4-01 or has not exceeded L4-01 + L4-02.
<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 = 0, the terminal opens during baseblock.
