5.7 H: Terminal Functions
Status
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 within the range of L4-03 ±L4-04.
Note: The detection level L4-03 is a signed value; detection works in the specified direction only.

Setting 15: Frequency Detection 3
The output opens when the output frequency or motor speed 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 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.
