The output closes when the actual output frequency or motor speed and the frequency reference are within the speed agree

width (L4-02) of the programmed speed agree level (L4-01).

Status

Description

Open

Output frequency or motor speed and frequency reference are not both within the range of L4-01 ±L4-02.

Closed

Output frequency or motor speed and the frequency reference are both within the range of L4-01 ±L4-02.

Note:

Frequency detection works in forward and reverse. The value of L4-01 is used as the detection level for both directions.

Setting 4: Frequency Detection 1

The output opens when the output frequency or motor speed 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 fall below the level set in L4-01.

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.

Note:

Frequency detection works in forward and reverse. The value of L4-01 is used as the detection level for both directions.
