Refer to L4-03, L4-04: Speed Agreement Detection Level and Detection Width (+/-) on page 145
Setting 15: Frequency Detection 3
The output opens when the output frequency 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 frequency or motor speed falls below the level set
in L4-03. The detection level L4-03 is a signed value; detection works in the specified direction only.
Status
Open Output frequency or motor speed exceeded L4-03 plus L4-04.
Closed Output frequency or motor speed is below L4-03 or has not exceeded L4-03 plus L4-04.

Setting 16: Frequency Detection 4
The output closes when the output frequency or motor speed (CLV, CLV/PM) is above the detection level set in L4-03. The
terminal remains closed until the output frequency or motor speed falls below L4-03 minus the setting of L4-04.
Status
Open Output frequency or motor speed is below L4-03 minus L4-04 or has not exceeded L4-03.
Closed Output frequency or motor speed exceeded L4-03.
Note: The detection level L4-03 is a signed value; detection works in the specified direction only.
