Refer to L4-01, L4-02: Speed Agreement Detection Level and Detection Width on page 308 for more instructions.
Setting 4: Frequency Detection 1
Output opens when the output frequency or motor 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 frequency or motor speed falls below the
level set in L4-01.
Note: Frequency detection works in both forward and reverse. The value of L4-01 is used as the detection level for both directions.
Figure 5. 70
<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.

Refer to L4-01, L4-02: Speed Agreement Detection Level and Detection Width on page 308 for more details.
Setting 5: Frequency Detection 2
Output closes whenever the output frequency or motor speed (CLV, CLV/PM) is above the detection level set in L4-01.
The terminal remains closed until the output frequency or motor speed falls below L4-01 minus the setting of L4-02.
Note: Frequency 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 frequency or motor speed exceeded L4-01 + L4-02.
Closed Output frequency or motor speed is below L4-01 or has not exceeded L4-01 + L4-02.
Status Description
Open Output frequency or motor speed is below L4-01 minus L4-02 or has not exceeded L4-01.
Closed Output frequency or motor speed exceeded L4-01.
