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.
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
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.
Status
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.
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.
Status
Open Drive is not in a baseblock state.
Closed Baseblock is being executed.
Setting 9: Frequency Reference Source
A contact output programmed for this function shows the frequency reference source that is currently selected.
Status
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.
