Setting 4: Frequency Detection 1
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 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.

Refer to L4-01, L4-02: Speed Agreement Detection Level and Detection Width on page 262 for more details.
Setting 5: Frequency Detection 2
Output closes whenever 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 falls below L4-01 minus the setting of L4-02.
Note: Frequency detection works in both forward and reverse. The value of L4-01 is used as the detection level for both directions.

Setting 6: Drive ready
Output closes whenever 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 drive’s internal power supply has malfunctioned
• When a parameter setting error makes it impossible to run
• Although stopped, an overvoltage or undervoltage situation occurs
• While editing a parameter in the Programming Mode (when b1-08 = 0)
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.
Status Description
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.
