Refer to L4-01, L4-02: Speed Agreement Detection Level and Detection Width on page 227 for more details.
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)
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.
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 digital output programmed for this function shows the frequency reference source that is currently selected.
Setting A: Run Command Source
A digital output programmed for this function shows the Run command source that is currently selected.
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.
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.
Status Description
Open Run command is provided from External reference 1 (b1-02) or 2 (b1-16).
Closed Run command is being sourced from the digital operator.
