Refer to L4-01, L4-02: Speed Agreement Detection Level and Detection Width on page 140 for more details.
Setting 5: Speed Detection 2
Output closes whenever the output speed or motor speed is above the detection level set in L4-01. The terminal remains
closed until the output speed or motor speed falls below L4-01 minus the setting of L4-02.
Note: 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 Up/Down 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)
• When parameter L8-88 = 0 and at least one Safe Disable input is open
Setting 7: DC bus undervoltage
Output closes whenever 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 Description
Open Output speed or motor speed is below L4-01 minus L4-02 or has not exceeded L4-01.
Closed Output speed or motor speed exceeded L4-01.
Status Description
Open DC bus voltage is above the level set to L2-05
Closed DC bus voltage has fallen below the trip level set to L2-05.
