Setting 5: Frequency Detection 2
Output closes when the output frequency or motor speed (CLV) 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 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 210 for more details.
Setting 6: Drive Ready
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
• Although stopped, an overvoltage or undervoltage situation occurs
• While editing a parameter in the Programming Mode (when b1-08 = 0)
Setting 7: DC Bus Undervoltage
Output closes when the DC bus voltage or control circuit power supply drops below the trip level set in L2-05. A fault in
the DC bus circuit will also cause the terminal to set for “DC bus undervoltage” to close.
Setting 8: During Baseblock (N.O.)
Output closes to indicate that the drive is in a baseblock state. While in baseblock, output transistors do not switch and no
main circuit voltage is output.
Setting 9: Frequency Reference Source
A contact output programmed for this function shows the frequency reference source that is currently selected.
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.
Status Description
Open DC bus voltage is above the level set in L2-05.
Closed DC bus voltage has fallen below the trip level set in L2-05.
Status Description
Open Drive is not in a baseblock state.
Closed Baseblock is being executed.
Status Description
Open Frequency reference is provided from External reference 1 (b1-01) or External reference 2 (b1-15).
Closed Frequency reference is being sourced from the digital operator.
