<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 is set to 0, the terminal opens during baseblock.
Refer to L4-03, L4-04: Speed Agree Detection Level and Detection Width (+/-) on page 321
for more details.
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
Description
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.
