1.7 H: Terminal Functions
Refer to L4-01, L4-02: Speed Agreement Detection Level and Detection Width on page 145
Setting 4: Frequency Detection 1
The output opens when the output frequency or motor speed (CLV, CLV/PM) 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
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.

Setting 5: Frequency Detection 2
The output closes when the output frequency or motor speed (CLV, CLV/PM) is above the detection level set in L4-01. The
terminal remains closed until the output frequency or motor speed fall below L4-01 minus the setting of L4-02.
Status
Open Output frequency or motor speed is below L4-01 minus L4-02 or has not exceeded L4-01.
Closed Output frequency or motor speed exceeded L4-01.
Note: Frequency detection works in forward and reverse. The value of L4-01 is used as the detection level for both directions.

Setting 6: Drive Ready
The output closes when the drive is ready to operate the motor. The terminal will not close under the conditions listed below,
and any Run commands will be disregarded.
• When the power is shut off
• During a fault
• When the internal power supply of the drive has malfunctioned
• When a parameter setting error makes it impossible to run
