set
agree 2)
Closes whenever the actual output frequency or motor speed (CLV, CLV/PM) and the frequency reference are within the
speed agreement detection width (L4-04) of the speed agreement detection level (L4-03). As the detection level L4-03 is
a signed value, detection works in the specified direction only.

Refer to L4-03, L4-04: Speed Agreement Detection Level and Detection Width (+/-) on page 308 for more details.
Setting 15: Frequency detection 3
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. As the detection level L4-03 is a signed value, the detection works in the specified direction only.

Status Description
Open Output frequency or motor speed and frequency reference are both outside the range of L4-03 ±L4-04
Closed Output frequency or motor speed and the frequency reference are both with in the range of L4-03 ±L4-04
Status Description
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 yet.
<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.
