Setting 6: Drive Ready
The 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: During Power Supply Voltage Fault
Output closes when the power supply voltage or the control circuit voltage falls below the drive operating voltage or when
the power supply frequency is incorrect.
Status
Description
Open
Normal
Closed
One of the following faults will occur:
AUv (Power Supply Undervoltage)
Uv (Undervoltage)
Fdv (Power Supply Frequency Fault)
Setting 8: During Baseblock (N.O.)
The 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
Description
Open
Drive is not in a baseblock state.
Closed
Baseblock is being executed.
Setting 9: Frequency Reference Source
Displays the currently selected frequency reference source.
Status
Description
Open
