Refer to L4-01, L4-02: Speed Agreement Detection Level and Detection Width on page 227 for more instructions.
Setting 4: Frequency Detection 1
Output opens when the output frequency 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 falls below the level set in L4-01.
Note: Frequency detection works in both forward and reverse. The value of L4-01 is used as the detection level for both directions.
